Homemade cyclone filter for a vacuum cleaner: a guide to action. Do-it-yourself cyclone filter or how to remove construction waste with a household vacuum cleaner Do-it-yourself cyclone for a vacuum cleaner dimensions

Cyclonic designs of household vacuum cleaners are considered one of the most successful technology options in terms of operating efficiency. The cyclone system is a relatively simple separation mechanism that makes it possible to effectively filter suspended particles present in the air stream.

Based on the theoretical principles of constructing such a system, it is quite possible to create a cyclone for a vacuum cleaner, acting as an additional tool - for example, a construction separator. Interested in the question, but don’t know how to make a simple cyclone yourself? We will help you realize your plans.

The article outlines detailed information about the design of a cyclone separator, and also provides step-by-step instruction on its assembly and connection to the vacuum cleaner. A description of all stages of the work process is accompanied by visual photographs.

Conclusions and useful video on the topic

About how to build another one with your own hands - more simple design cyclone, the video below clearly shows and explains.

The author uses this homemade system in everyday practice and is extremely satisfied. A cyclone separator, made from an ordinary bucket, helps to work in clean conditions in the production of household goods. construction work:

Self-assembly of a cyclone for a vacuum cleaner is acceptable and quite possible. Moreover, there are projects of similar “homemade” systems that can actually be made, if not in 2 minutes, then in a couple of hours. Such a cyclone is really worth spending some time on its manufacture. Costs are fully reimbursed.

When machining various materials, large amounts of chips can be generated. With its removal manually many difficulties arise. To significantly simplify the procedure under consideration, special devices called chip ejectors began to be used. They can be found in specialized stores; the cost varies over a fairly wide range, which is associated with functionality, performance and popularity of the brand. If desired, such equipment can be made with your own hands, for which it is enough to know the types and principles of operation.

Principle of operation

You can do a cyclone-type chip ejector with your own hands only after determining the basic principles of operation. The features include the following points:

1. A corrugated hose of small cross-section is connected to the main body, which concentrates and enhances traction. The tip may have different attachments, it all depends on the specific task at hand.
2. At the top of the structure there is a motor, which is directly connected to the impeller. During rotation, the air is discharged, thereby creating the required thrust.
3. During suction, the chips settle in a special container, and the air is discharged through a special pipe on which a coarse filter is installed.
4. A fine filter is also installed at the outlet pipe, which traps small particles and dust.

In general, we can say that the operating principle of cyclone-type chip ejectors is quite simple, due to which the design is characterized by reliability.

Types of chip ejectors

Almost all models of cyclone chip ejectors are similar. In this case, the main mechanisms, for example, the engine or the cyclone system, may differ slightly, which determines the main classification. All cyclone type chip extractors can be divided into several categories:

1. For household use.
2. Universal.
3. For professional use.

When choosing a model for a home workshop, you should pay attention to the first two groups of equipment. This recommendation is due to the fact that their cost should be relatively low, while the performance will be sufficient.

If you frequently carry out work in the workshop, there is a large amount of shavings, and if you are providing professional cleaning services for workshops and other premises, you should consider when choosing cyclone-type chip ejectors from the professional group. This is due to the fact that it is characterized by higher performance and reliability, and can withstand long-term use.

Cyclone type chip suction device

Most models resemble a regular vacuum cleaner, which, due to its strong traction, sucks up large and small chips. However, even a powerful and high-quality vacuum cleaner cannot be used to clean the workshop. Main structural elements can be called:

1. A flange-type electric motor is installed, the power of which is only 3.5 kW.
2. To discharge the air, a fan with a durable and mechanically resistant impeller is installed. It must be large enough to produce the required thrust.
3. The cyclone is designed to purify the air that will be exhausted outside. Its device is designed to filter large elements.
4. A multi-stage filter significantly increases the efficiency of the procedure. This is due to the fact that at the primary stage, large elements are separated, after which small ones are separated. Through multi-stage cleaning, you can significantly extend the life of the filter and increase its efficiency.
5. The lower cyclone is intended for direct collection of chips.
6. A collection bag made of durable material is designed to temporarily store chips and other debris that have been separated from the passing air flow.

High-quality models have a sealed body, which is lined with sound-absorbing panels. To control a cyclone-type chip extractor, an electrical or mechanical unit is placed; there must be a special hole for connecting a corrugated hose with a nozzle.

It is not difficult to make a cyclone-type chip extractor with your own hands, since it is in many ways reminiscent of a conventional vacuum cleaner with big amount filter elements and high power. The structure of the woodworking cyclone is characterized by high reliability, if you follow the operating instructions, the device will last a long time.

Design features

In most cases, when making a cyclone chip pump yourself, a low- and medium-capacity motor is installed, which can be powered from a standard 220V network.

More powerful units are supplied three-phase motors, with food in living conditions Quite a lot of difficulties arise.

Among design features It should be noted that the impeller is installed to ensure spiral turbulence of the air flow. In this case, heavy particles are dumped into a special container, after which centrifugal force again lifts the air to remove it.

Preparatory work

When making a structure with your own hands, you can save a lot, but some mechanisms still cannot be assembled yourself. An example would be the most suitable motor and impeller. The preparatory stage includes the following actions:

1. Formation of an action plan for assembling homemade equipment.
2. Searching for a suitable electric motor, checking its condition.
3. Selection of other mechanisms that cannot be made by hand.

In a carpentry workshop, much of what is required to create cyclone-type chip ejectors can be made with your own hands.

Tools

Depending on the chosen scheme, a variety of tools may be required. The easiest way is to make the outer casing from wood. It is to this that other elements will be connected. The recommended set of tools is as follows:

1. Indicator and multimeter.
2. Chisel and other tools for working with wood.
3. Screwdriver and various screwdrivers, hammer.

The simplicity of the design determines that it can be manufactured with the most common tools.

Materials and fasteners

The device being created must be light and airtight, and also withstand the pressure exerted by air swirling. To make it you will need:

1. The body can be assembled from plywood, the thickness of which is about 4 mm. Due to this, the structure will be durable and lightweight.
2. To make other parts, you will also need pieces of wood of various thicknesses.
3. Polycarbonate.
4. The filter can be taken from a VAZ injection type. Such a filter is cheap and will last quite a long time.
5. The engine can be removed from an old powerful vacuum cleaner, the impeller will be mounted on the output shaft.
6. To connect the main elements you will need screws, self-tapping screws, bolts with nuts, and sealant.

After finding everything you need, you can start doing the work.

Making a cyclone filter

As previously noted, making a filter is quite difficult; it is best to purchase a cheap one already ready-made option execution. However, it will also require a sealed seat.

The seat is also made of wood. In this case, the main thing is to correctly select the appropriate diameter of the outlet hole, since too small will lead to a decrease in bandwidth. There is no need to attach the filter, just create a block for it that will fit perfectly in size.

Creating a retaining ring and a shaped insert

To fix the polycarbonate during the manufacture of the case, wooden rings are required. They must have an internal diameter that provides the required volume of the storage tank. Between the two fixing rings there will be vertical strips holding the polycarbonate sheets.

You can make such rings in a home workshop if you have the appropriate skills and equipment. At the same time, do not forget that they must have high strength.

Installing the Retaining Ring

Assembling the case can begin by placing the locking wheels and polycarbonate sheets. Among the features of this stage the following points can be noted:

1. The sheets are fixed on both sides with strips.
2. The connection is made using self-tapping screws.
3. To improve sealing, slots are created in the lower and upper rings for sheets, after installation of which the seams are sealed with sealant.

After assembling the housing, you can begin installing other structural elements.

Installing the side pipe

In order to eliminate the possibility of rupture of the structure due to clogging of the filter element, a side pipe with a safety valve is installed. To do this, a hole is created in the polycarbonate sheet, which is closed on both sides by the body of the safety pipe.

A rubber gasket should be placed between the wooden planks and the wall; the degree of sealing can be increased by using sealant. The element is secured to the body using bolts and nuts.

Top entry installation

Suction of chips and air occurs from the top of the structure. To accommodate the upper input, a small housing is created in which the pipe from the old vacuum cleaner is placed.

When using a special pipe, reliable fixation of the suction hose is ensured, which, moreover, can be quickly removed if necessary. That is why you should not make it yourself.

Installing a shaped insert

A shaped insert is also required to connect the inlet pipe. It must be positioned so that air containing particles can flow in without difficulty.

As a rule, the figure is located opposite the fan, due to which the air flow swirls. It is best to seal the seams with sealant, which will increase the degree of insulation of the structure.

Cyclone filter assembly

After creating a housing to house the filter, it needs to be installed in its place. It is worth considering that there will also be electronic elements inside that provide power to the electric motor.

Another pipe is removed from the outer part of the cyclone filter housing. It will be needed to divert the air flow.

Principles for choosing a chip ejector and the main manufacturers

Quite a large number of different companies are engaged in the production of cyclone-type chip ejectors. The principle of operation of the device is no different, only the power and reliability of the design increases.

Cyclone-type chip ejectors from foreign brands are more popular; domestic ones are cheaper, but last much less.

When working in a workshop or at home with a grinding tool, when processing parts and preparing surfaces, the need arises to remove fine dust. And, of course, it is advisable to reduce its concentration even during work by organizing local constant air purification at the workplace.

At enterprises, this problem is solved by installing filter units with a cyclone, which collects and sediments dust with the required efficiency.

In our case it is enough make a vacuum cleaner with a cyclone, thereby saving on the purchase of a construction vacuum cleaner, where such a function is provided by the manufacturer.

The principle of operation of a homemade construction vacuum cleaner with a cyclone filter

There are several options for making a cyclone for household needs. To decide on the most effective scheme operation of the equipment, you should know the operating principle of this filter.

Cyclone in classic version It is a cylinder and a cone, in the upper part of which there is an inlet for polluted air and an outlet for purified air.

The inlet is made so that the air enters the filter tangentially, forming a rotating flow directed towards the equipment cone (down).

Inertial forces act on pollutant particles and carry them out of the flow to the walls of the apparatus, where dust settles.

Under the influence of gravity and secondary flow, the mass deposited on the walls moves towards the cone and is removed into the receiving hopper. The purified air rises up along the central axis and is discharged through a pipe located strictly in the center of the upper platform of the cyclone.

A prerequisite for effective air purification is the accurate design of the apparatus and the tightness of the cyclone, including in relation to the receiving hopper.

Otherwise, the principle of operation is disrupted and chaotic air movement occurs, preventing dust from settling normally.

In addition, it is necessary to select a motor that sucks in contaminated air, which will ensure optimal operating parameters of the equipment.

Homemade filter for a construction vacuum cleaner, the variants of which are offered on the Internet cannot be called a full-fledged cyclone.

The most simple circuit Such equipment is a plastic barrel with an embedded inlet pipe tangentially, a built-in filter from a car inside the “cyclone” body, through which purified air is removed and to which a household vacuum cleaner is connected.

The disadvantages of the equipment are the absence of a formed flow swirling along the walls of the barrel and a laminar return flow.

In essence, we get an additional capacity for settling large particles (sawdust, shavings), and fine dust will clog the filter at the outlet, and will require constant cleaning.

To improve the design, we suggest supplementing the plastic barrel with a homemade cyclone made from traffic cone. It is best to install a stationary version of equipment for removing dust from the workplace if work is carried out over several hours.

In this case, we need a radial household fan. And with a one-time connection of the cyclone, it is enough to use a regular vacuum cleaner with adjustable suction power.

Sometimes an additional rheostat is installed to reduce the rotation speed of the vacuum cleaner engine, thereby selecting the parameters necessary for the normal functioning of the filter.

In the following sections of the article we will present you with two options for a cyclone for domestic use.

Selection of equipment - what is needed for work

For the first design option for a permanent installation, you will need the following components:

• Plastic barrel;
• Gray plastic sewer pipe with a diameter of 50 mm;
• Traffic cone;
• Corrugated hoses, reinforced with steel wire or metallized hoses;
• Adhesive for plastic;
• Radial household fan with the ability to change the engine speed and performance equal to six times the exchange of air in the room;
• Plywood 10-12 mm thick.

The second version of the product is the most successful, since in this case the product approaches the functionality of a real cyclone.

To make a filter you will need to purchase:

• Ready-made plastic cyclone made in China;
• A barrel, bucket or other container for making a dust bin;
• Corrugated hoses.

A plastic cyclone is inexpensive, approximately 1500-2500 rubles, and is designed to collect medium and heavy dust. Works great with shavings and sawdust.

Step-by-step instructions for the cyclone assembly process

Our first option is stationary design for workshops with large amounts of dust of various origins.

1. First we make the cyclone itself. We make a hole in the plastic cone for passage sewer pipe on a tangent.
2. To better connect the pipe to the cone body, matte the mating surfaces with emery cloth. We glue the seams using a mounting gun.
3. In the upper part of the cone we install a vertical pipe, the lower end of which should be below the inlet. In this way we can achieve vortex air movement. The pipe is fixed in a plywood sheet in the shape of a circle with a diameter equal to the size of the base of the cone.
4. The prepared cyclone is secured to the barrel lid using a round plywood sheet.
5. To prevent the plastic barrel from becoming deformed under the influence of vacuum when the inlet pipe becomes clogged with debris, we install a spacer inside the container - a frame made of plywood sheet. The external dimensions of the frame follow the internal diameter of the barrel. To strengthen the structure, we attach the construction cone to the lid of the container using metal pins.
6. Next, we connect the cyclone to the corrugated hoses at the inlet and outlet. We install a radial household fan outdoors under a canopy.

The second version of the construction vacuum cleaner is based on a Chinese plastic cyclone, which is also attached to any of the selected containers. The result is a reliable and efficient design.
The cyclone is attached to the container using a metal clamping flange.

VIDEO INSTRUCTION

When starting the vacuum cleaner and further operation, do not forget to clean the inlet pipe and stop the internal spacers on the containers to prevent deformation of the receiving hopper.

If finer air purification is required, the design is supplemented with a car filter in the housing at the outlet of the product.

During renovation and construction work, a lot of debris appears. Sawdust, shavings, scraps of materials mixed with dust must be removed regularly. Regular sweeping with a mop is excluded due to the specifics of the work, if dust and small particles can stick to the surface, for example, after priming or painting.

An ordinary vacuum cleaner will not cope with such debris or will quickly break down. Household electrical devices designed for medium short-term load.

For such cases, specialized equipment is produced. A construction vacuum cleaner can work for quite a long time without stopping, has significant power, and uses completely different filter systems than household vacuum cleaners.

When should you use a construction vacuum cleaner?

Those who are constantly faced with construction, repair and carpentry work know about the need for timely cleaning of the workplace at the end of the stage. Cleaning can be done multiple times in one day, so it’s reasonable to want to make the process easier for yourself.

Pieces of foam and polyethylene film , scraps of gypsum board, chipped plaster, dust from cutting aerated concrete - all this debris settles not only on horizontal surfaces, but is also electrified and attached to vertical walls.

Cleaning with a mop and dustpan is not always appropriate due to large areas, and washing will only turn dry dirt into wet slurry, especially in unfinished rooms.

Due to the small size of the dust container, a regular household appliance will quickly become clogged and will have to be continuously cleaned. If large particles get in, there is a high risk of breaking the equipment.

It is in such conditions that the best solution would be to use a construction vacuum cleaner.

Pros and cons of a construction vacuum cleaner

High power allows professional equipment to work without interruption for quite a long time, and a long hose provides access to remote areas without the need to carry the vacuum cleaner or interrupt work.

But it also has disadvantages:

• High price. If periodic or one-time work is required, purchasing a new expensive tool is not practical.
• Large size and weight.

Some craftsmen have come up with a way out in the form additional option to existing technology. At a relatively low cost you can collect cyclone filter for a vacuum cleaner with your own hands. This design will increase the capabilities of an existing conventional household vacuum cleaner.

Making a cyclone with your own hands

There is a huge selection of instructions on the Internet. self-production cyclone filter, including attached drawings and photographs. But they are united by a standard set of components.

So, what do we need:

Assembly instructions.

The main indicator that a cyclone for a vacuum cleaner is assembled correctly with your own hands will be debris collecting at the bottom or settling on the walls of the container, while the suction will be fast and high-quality. Do not forget to check the tightness of the structure.

The history of the cyclone filter

The creator of cyclone filter technology is James Dyson. It was he who first made a filter with operation based on the action of centrifugal force. Why did this device become so popular and in demand that the inventor filed a patent for it?

The filter consists of two chambers. Under the influence of centrifugal force inside the unit, the debris begins to swirl into the funnel. Large trash at the same time, it settles in the first chamber, the outer one, and dust and light debris collects on the inside. This way, clean air comes out through the top hole.

The main advantages of the cyclone filter:

• no need for dust collection bags and their constant replacement;
• compact filter sizes;
• quiet operation;
• An easy-to-remove lid allows you to regularly check the level of contamination and promptly dispose of garbage;
• speed and efficiency of work.

A vacuum cleaner with a cyclone filter can be used both at home and for professional purposes.

When processing wooden blanks, everyone has probably encountered the fact that everything around is covered with a large amount of shavings, sawdust and wood dust. To at least partially get rid of them, various dust collectors, chip suckers, filters and other devices are used. Many power tools and machines have their own dust collectors, while others have special outlets for connecting a vacuum cleaner.

In home workshops it would be better to use special ones. vacuum cleaner than a household one. Firstly, the engine is special. The vacuum cleaner is designed for more than long-term operation, and secondly, as a rule, it is equipped with a hose with a length of 3 m, which significantly simplifies its use with power tools. And yet, the downside of every vacuum cleaner is a small container for garbage.

How to make a cyclone filter with your own hands

Having set out to somehow simplify the work of cleaning a vacuum cleaner and reduce the cost of bags, I began to collect information on this issue. Found a description on the Internet different types simple devices in the form of intermediate dust collectors for a vacuum cleaner. Firstly, these are dust collectors in the form of a mini-cyclone. They perform their function well in collecting dust in a separate container, preventing it from getting into the vacuum cleaner, which increases the service life of the bags tens of times. The process of cleaning the dust collector from debris is also simplified. Ready-made devices are sold through online stores, but their cost is quite high with a very simple design.

Design. I decided to make a mini-cyclone dust collector myself. The author and developer of this design is considered to be Bill Pentz from California. Having developed a serious allergy to fine wood dust, he subsequently devoted a lot of time and effort to fighting both the disease itself and its causes.

The dust collector is a device, the main element of which is an inverted truncated cone, inserted with its lower part into a dust collection container. A tube for connecting to a vacuum cleaner is inserted into the upper part of the dust collector, and on the side, tangentially, there is a tube for connecting the hose from the tool.

When a vacuum cleaner draws in air inside the device, turbulence is formed, and debris, moving along with the air, is thrown back by centrifugal forces to the inner walls of the filter, where they continue to move. But as the cone narrows, the particles collide more often, slow down and, under the influence of gravity, fall into the lower container. And the partially purified air changes direction and exits through a vertically installed pipe and enters the vacuum cleaner.

There are two mandatory requirements for this design. This is, firstly, its tightness, otherwise there will be a sharp loss of suction power and quality of air purification. And, secondly, the rigidity of the container and the cyclone body itself - otherwise it tends to flatten.

There are tables on the Internet with drawings of cyclones for different particle sizes. You can make the cyclone body yourself from galvanized steel or plastic, or you can select a ready-made container of a similar shape. For example, I have seen cyclones made on the basis of a traffic cone (necessarily hard), a plastic flower vase, a tin horn, a large tube of toner from a copy machine, etc. It all depends on what size cyclone is needed. The larger the debris particles, the larger the diameter of the tubes for the connected hoses and the more massive the cyclone itself becomes.

Bill Pentz points out some of the features of his design. So, the smaller the diameter of the cyclone, the greater the load on the vacuum cleaner. And if the garbage container is low and flat, then there is a possibility of debris being sucked out of the container and falling into the vacuum cleaner. When using a container of any shape, it should not be filled to the top with debris.

Choice of material. I decided to use it as blanks plastic pipes For external sewerage and fittings for them. Of course, it will not be possible to create a full-fledged cone from them, but I was not the first to try to use them for this purpose. The advantage of this choice is the rigidity of the parts and the tightness of their connections due to the seals. Another plus is that there are various rubber pipe inserts that allow you to easily and tightly connect the vacuum cleaner hose. In addition, if necessary, the structure can be easily disassembled.

For mine, to collect large sawdust and shavings, I made a cyclone from a ∅160 mm pipe. I used ∅50 mm pipes as connectors for the hoses. I would like to draw your attention to the fact that the eccentric adapter from a pipe ∅110 mm to ∅160 mm must be funnel-shaped. I've seen flat ones, but they won't work - nothing will work with them, and the debris will get stuck.

Do-it-yourself cyclone work progress

Operating procedure. In the plug for the ∅160 mm pipe and in the body pipe, I made holes for outlets for hoses. Next, using a heat gun, I glued a piece of ∅50 mm pipe into the plug. It should be located in the middle of the cyclone body and be a couple of centimeters below the side tube, so it is better to first glue a longer pipe into the plug and then cut it in place during assembly.

I found complaints online that the hot melt adhesive does not stick to PVC pipe, and advice to weld parts using a soldering iron and pieces of the pipe itself. I tried, but didn't do it. Firstly, the glue stuck perfectly to me, and secondly, the smell of melted plastic discouraged anyone from welding anything this way, although the connection would probably be stronger and more accurate.

The difficulty of working with hot-melt adhesive is that it does not spread, and if you lack the skills, the seam will not be very smooth. I had such a sad experience - to straighten the seam I decided to heat it with a hairdryer. I got a smooth surface of the adhesive bead, but at the same time the plastic tube itself was deformed and had to be thrown away.

At the next stage, I glued a spiral to the inner surface of the body, which should guide air flow down to the dust collector. This solution was recommended by Bill Pentz himself - according to him, this almost doubles the efficiency of the cyclone. The spiral with a height of about 20% of the gap should fit tightly to the body and make one turn with a pitch equal to the diameter of the inlet hole for the side pipe.

As a material for it, I used a plastic rod, which I heated with a hairdryer and bent into a spiral shape. (photo 1), and then glued it into the body (photo 2) using a heat gun. Then I glued the side tube (photo 3), the inner end of which is directed slightly downwards.

Once the glue cooled and hardened, I measured and cut the vertical outlet tube so that it was 2-3 cm below the cut of the side tube, and finally assembled the entire structure.

I made a container for garbage from a hard plastic barrel, to the bottom of which I attached wheels - this turned out to be very convenient for cleaning it (photo 4). I cut a viewing window on the side of the barrel and covered it with acrylic glass on hot glue. I reinforced the connection from above with a plastic ring and bolts. Through such a porthole it is convenient to monitor the filling of the container.

I didn’t have a lid for the barrel, so I made it from a piece of countertop that had been waiting in the wings for a long time after installing a sink in the kitchen (photo 5). On the underside of the tabletop, I used a router to select a groove for the edges of the barrel and glued a window seal into it to seal the joint. (photo 6). According to the rules, the hole in the lid should be made in the center, but then I would have problems with placing the cyclone in the workshop, so I made the hole offset. The lid is attached to the barrel using latches from a long-broken vacuum cleaner. I also used a hose from it to connect the cyclone. I would like to draw your attention to the fact that it is better to take hoses from vacuum cleaners. If you take, say, a corrugated pipe for electrical wiring, when you turn on the vacuum cleaner, a whistling and terrible noise appears.

DIY cyclone for vacuum cleaner

Wiring. After checking the performance of the cyclone, I decided to make a stationary distribution of hoses throughout the workshop, since a three-meter hose is certainly not enough, and a vacuum cleaner with a cyclone is bulky and clumsy, and it is inconvenient to move them around the workshop every time.

Thanks to the fact that standard pipes were used, it was possible to install such wiring in an hour. I pushed the vacuum cleaner and cyclone into the farthest corner, and laid pipes ∅50 mm around the workshop (photo 9).

In the workshop I use a specialized BOSCH green series vacuum cleaner. After four months When using it in conjunction with a cyclone, I can say that on the whole they cope with their task. But I would like to slightly increase the suction power (when working with a jigsaw you have to move the hose almost close to the cutting zone) and reduce the noise level. Since little shavings get into the vacuum cleaner itself, there is an idea to make a more powerful impeller and move it outside the workshop to the street.

I can also say that the suction power of the vacuum cleaner dropped a little when using it with a cyclone, but this is not very noticeable at work. There were doubts that static electricity could accumulate on the elements, since the entire structure is plastic, but practically this does not happen, although previously the hose had to be grounded when collecting fine dust.

Of course, when using professional pipelines with large outlet openings, this diameter is not enough. It is better to take ∅110 mm or more, but then both the vacuum cleaner and the cyclone must be more powerful. However, for my homework this is quite enough.

The vacuum cleaner hose was firmly secured to a small branch of the pipe ∅50 mm and inserted into in the right place wiring. The remaining wiring outputs are closed with plugs firmly placed on short bends. Moving the hose is a matter of seconds.

During operation I encountered one small problem. If a small pebble (my concrete floors have not been repaired for a long time) or another small but heavy object gets into the hose, it moves through the pipes to the vertical section in front of the cyclone and remains there. When such particles accumulate, other debris clings to them, and a clog can form. Therefore, in front of the vertical section of the wiring, I embedded a camera made of a ∅110 mm pipe with an inspection window. Now all the heavy debris collects there, and by unscrewing the lid it is easy to get out. This is very convenient when a fastener or small part accidentally gets into the vacuum cleaner. It’s simple here - I unscrew the lid, turn on the vacuum cleaner and mix everything that remains in the revision with my hand. Small particles They immediately fly into the cyclone container, but the large ones remain and are easily removed. Their quantity is usually insignificant, but recently I found a missing screwdriver bit in such garbage.

Also, the inspection hole can be used to temporarily connect a hose ∅100 mm. Just unscrew the lid and you get a finished hole ∅100 mm. Naturally, in this case it is necessary to mute all other wiring inputs. To simplify connection, you can use a flexible adapter (photo 10).

I use all of these devices regularly. I'm pleased with the result - there is noticeably less dust in the workshop, making cleaning easier. During this time, I collected several bags of sawdust, and very little debris accumulates in the vacuum cleaner. I want to check the cyclone for collecting small garden debris and dust when cleaning a concrete floor.

I think this design is very useful and affordable to make at home.
