Those who have ever dealt with construction or renovation know first-hand what a good vacuum cleaner is for. In the fight against sawdust and metal shavings, concrete dust and various small fragments, an industrial construction vacuum cleaner will be indispensable. However, before purchasing it, it would be nice to understand what such a unit is intended for and what nuances you need to pay attention to when choosing it.

Why do you need an industrial construction vacuum cleaner?

The industrial dust collector is designed for quick and safe collection of construction waste. With its help, the room can be cleaned of sand, residues of dry mixtures, glass fragments, metal and wood shavings, powder abrasives, small elements and even liquid dirt, water and oil. Some units are capable of removing even small crushed stones and pieces of knocked down plaster. If you need to collect water before work, then a construction vacuum cleaner can handle this too.

Industrial units differ from household models:

• high performance;
• long period of operation;
• noiselessness;
• compactness.

Their shockproof the body is made of durable steel and painted with protective paint. Construction vacuum cleaners are equipped with:

1. Engine with increased wear resistance.
2. Multi-stage air filtration system.
3. Capacious trash tank.
4. Rubberized wheels for easy movement on any surface.

Industrial devices are capable of absorbing fine dust and sucking up liquid. They are not cheap, so you can’t go wrong when choosing a unit for collecting construction waste.

Criteria for choosing an industrial construction vacuum cleaner

Before purchasing such a unit First of all, you should determine the volume and nature of contamination, which he will have to cope with.

Choosing a dust collector for its intended purpose

The technical characteristics of the equipment indicate the classes to which a particular vacuum cleaner model belongs.

Therefore, to successfully implement the task, you should choose more omnivorous models of industrial vacuum cleaners.

Choosing a vacuum cleaner based on engine power

If dust collectors for domestic use have a power of about 300 watts, then the power of construction units most often exceeds 1.5 kW. Among the models of industrial construction vacuum cleaners are:

1. Starmix GS 2078 PZ with a 2400 W motor.
2. Metabo SHR 2050 M, equipped with a “Soft Start” system.
3. Makita 449 with two motors, each with a power of 1200 watts. The model has double productivity, a vacuum of 27 kPa and an air flow of 390 m3/hour.

The air performance and degree of vacuum of a vacuum cleaner are one of the main criteria when choosing it. Therefore, when comparing models, it is imperative to pay attention to these readings.

Vacuum cleaners with powerful motors are able to suck up debris better and work for a long time without turning off. Units capable of absorbing liquids must be equipped with well-insulated motors and special air cooling, capable of preventing liquid from entering live elements.

When choosing an industrial vacuum cleaner, it is recommended to pay attention to such a parameter as engine speed. After all, the higher the turbine rotation speed, the better filtration the unit can provide. Some models are available with a high turbine speed of 30,000 rpm.

One of the signs of the reliability and manufacturability of an industrial vacuum cleaner is its low noise level during operation.

When choosing a vacuum cleaner with a high-quality motor, you should keep in mind that graphite brushes usually do not last very long. Therefore, in order to avoid windings and short circuits, it is recommended to replace them on time. Most often this is done after 1-1.5 thousand hours of operation.

Types of filtration of industrial vacuum cleaners

When choosing a unit for cleaning construction waste, you need to pay attention to the principle by which filtration occurs.

The main principles of filtration of construction vacuum cleaners:

Any filter must be cleaned from time to time, since when they become dirty, the performance of the unit decreases significantly. Manufacturers can offer various methods for cleaning filters:

• manual cleaning with a special comb, in which the device does not need to be dismantled;
• cleaning using a pneumatic shock, during which air passes through the filter in the opposite direction and the filter is cleaned.

Many models of industrial vacuum cleaners can be equipped with several filtration methods at once. Their kit may include bags, containers and filters. Nylon filters are intended for disposable dust collectors, polyurethane filters for removing liquids, and pleated filters for containers.

How to choose the layout of a construction vacuum cleaner

Most industrial dust collectors have a basic package that includes:

• frame;
• long hose;
• container;
• various nozzles;
• transition elbow;
• pipe;
• filters;
• dust collectors;
• tool adapter.

It is better to choose a unit designed for collecting large amounts of construction waste with a container volume of 50-60 liters. At the same time, modern models have compact dimensions and low weight.

If you are not expected to work with a large amount of garbage, then you can choose easily transportable models with a small container. With a suction equivalent of 5.4 kg, the container volume of such a unit can be only 9.6 liters.

When choosing an industrial vacuum cleaner, you should pay attention to the location of its pleated filter. In cylindrical models it takes up a lot of useful space. That's why It’s better to choose units with a filter, placed outside the vacuum cleaner tank. The use of flat cassettes makes it possible to free up space inside the tank.

To protect the power plant from overloads, the vacuum cleaner must be equipped with a special system. Some models turn off when they overheat and the tank is full while collecting water. Frame can be equipped with LED indication, which indicates that the dust container is completely full or the filter or hose is clogged.

When choosing a construction industrial vacuum cleaner, it is recommended to pay attention to its wheels, since when moving the unit should not leave furrows on the new floor covering. For this purpose, “piano” wheels were invented. Heavy weight units must be equipped with special frame trolleys with rubberized wheels. Since you often have to roll a decent amount of garbage, such carts must be functional and reliable. Some units may have a foot brake, which is very convenient when working with them.

An additional water drainage pipe will greatly simplify the maintenance of the dust collector. On some models, there are special slots on the body where various attachments are stored. In addition, the vacuum cleaner must be equipped with a reliable and long power cord.

Taking into account the conditions under which industrial vacuum cleaners are used, manufacturers use durable materials to make their housings. It can be brass, aluminum, stainless steel or steel. The use of fragile plastic is excluded.

The most popular and best models of construction units are those produced by companies engaged in the production of professional equipment for cleaning companies, dry cleaners and car washes.

Of course, each manufacturer praises its own product. Sometimes it can be quite difficult to make a choice in favor of any one model. Therefore, first of all, it is necessary to decide on the type of pollution with which to work. After this, you should pay attention to the performance of the unit, its filtration system and the duration of non-stop operation. Necessarily It is recommended to ask about the basic equipment and whether it is necessary to purchase any additional elements. All this will allow you to determine the price-quality ratio of the selected industrial construction vacuum cleaner. In addition, it is worth asking how accessible service is for the selected unit in your region.

What is the difference between a construction vacuum cleaner and a household or specialized industrial vacuum cleaner? What tasks can be set for him? How to choose the right model? What nuances should you pay attention to first? These questions are asked by everyone who decides to acquire such a device. We hope that this article will help you make the right choice.

The progenitor of all vacuum cleaners was patented in 1860. It was powered by hand bellows, and its dust collector had, by today's standards, a very innovative design - it was a container filled with water. At the turn of the century, models with a gasoline engine appeared, and a little later (1907) an electric unit. The new miracle of technology, despite its imperfections, was liked by everyone; the potential for development was visible to the naked eye. The industrialists rubbed their hands. In 1912, the Swedes launched mass production of “snorting machines”; by the 20s, the vacuum cleaner became similar to modern models - something like the good old Soviet “Rocket”.

Now we cannot imagine our life without vacuum cleaners, which are used everywhere. They successfully fight almost any type of pollution, not always dust. There are dozens of types of vacuum cleaners, thousands of models, both with a narrow specialization and a more universal focus. Household, industrial, explosion-proof, low-voltage, pneumatic, gasoline, stationary, backpack, hip, battery, robotic, washing, steaming, automobile, garden - the list is long.

We are more interested in construction and industrial vacuum cleaners, which help craftsmen while working with hand tools, on machines, and simply for cleaning the area. The fact is that making the right choice of an expensive device is quite difficult - manufacturers are constantly coming up with something new, forcing us to delve into all the intricacies. It's okay, we'll manage.

What can a construction vacuum cleaner do? To each according to their needs...

Builders, European-quality repairers, have learned from their own experience that the object must be handed over after general cleaning, otherwise do not expect “mercy” from the customer. Some of them prefer to keep the workplace clean “in the process.” This habit has a very positive effect on both the health of the masters and their productivity. In addition, most types of construction and finishing operations should be carried out only after careful preparation of the base - it must be spotlessly clean. This is where industrial vacuum cleaners come to the rescue, whose direct responsibility is to quickly and safely remove construction waste.

Household appliances decommissioned from domestic service in difficult conditions perish instantly, and after a short period of use they bring little benefit. By the way, there are known successful (!) cases of handicraft production of a construction vacuum cleaner based on a motor from Raketa using a car (“Moskvichev”) air filter.

Wooden and metal shavings, glass fragments, remains of dry mixtures, sand, powdered abrasives, oils, water, liquid dirt, small bolts/nuts/screws - there is more than enough of this stuff on a construction site, a construction vacuum cleaner can handle all of it. Some “strong men” are able to remove even pieces of knocked down plaster or not very large crushed stone. There are vacuum cleaners that can be used to collect water; for example, you need to dry the bottom of a pool bowl that has been flooded with rain. Electric tools, in turn, generate a huge amount of harmful fine dust, which is best removed immediately. A special contribution to this matter is made by all kinds of grinding machines, wall chasers, hammer drills, grinders... To neutralize these harmful substances, you will need devices with fine multi-stage air purification.

So, if you decide to get an industrial vacuum cleaner, you should first decide on the nature of the pollution, and based on this, start choosing based on other parameters. The greater the degree of omnivorousness of the unit, the less likely it is that the vacuum cleaner will not cope with the task.

Construction vacuum cleaner motor

The heart of a vacuum cleaner is the motor. The performance of the unit as a whole directly depends on its power. If for household models 300 watts is enough, then industrial vacuum cleaners safely exceed the 1.5 kW mark (Starmix GS 2078 PZ - 2400 W). The more powerful the engine, the better the device sucks up debris, the longer it can work without turning off. It is not surprising that some vacuum cleaners are equipped with a “soft start” system (Metabo SHR 2050 M). Makitovites proposed an interesting unit with two engines, each of which has a power of 1200 watts. Accordingly, the Makita 449 model amazes with its doubled productivity (air flow - 390 m 3 / hour, vacuum - 27 kPa) and omnivorousness.

Indicators of the efficiency of a vacuum cleaner are the degree of vacuum (indicated in bars or pascals) and air output (liters per minute or cubic meters per hour). With all other characteristics being equal, the two models being compared are definitely worth a look.

The motor of an industrial vacuum cleaner is usually designed for a voltage of 220 volts, but there are “serious” three-phase devices (Sibilia DS 1505) and 28-volt battery-powered “babies”.

An important parameter of the engine is its speed. The high rotation speed of the turbine allows for better filtration; in some models it reaches 30,000 rpm.

For vacuum cleaners designed to remove liquids, well-insulated motors with special air cooling are used, thanks to which moisture does not enter live elements.

Note that a high-quality motor of a construction vacuum cleaner lasts much longer than its graphite brushes. Therefore, in order to avoid short-circuiting the windings, they must be replaced in time. As a rule, the life of brushes is limited to 1-1.5 thousand hours.

The low noise level of a working industrial vacuum cleaner is certainly a sign of the manufacturability and reliability of its power plant.

Choosing a vacuum cleaner based on the filtration principle

All vacuum cleaners work according to the same scheme: the engine creates a vacuum, air along with debris is sucked into the tank, cleaned through various filters and discharged outside. There are three basic principles of filtration, and they all have their pros and cons.

The first version of vacuum cleaners are those in which debris and dust are collected by filtration into a special bag. This dust collector can be made of cloth or paper. The first ones are permanent, they only need to be destroyed from time to time. They are suitable for collecting large particles and provide only coarse filtration, while very fine dust passes through or even clogs them. Replacement bags are discarded when filled and are made from paper or non-woven composites. They are excellent for filtering fine dust about 0.3 microns in size and help remove even allergens and odors. But particles with sharp edges (glass, metal shavings) quickly destroy such dust collectors.

The second option is cyclone technology. Here, filtration objects are collected under the influence of centrifugal force into a built-in filter container. Such vacuum cleaners are good for collecting liquid or moistened debris.

The third group is vacuum cleaners with an aqua filter. In this case, the air, sprayed, passes through a container of foamed water and leaves large dust there. Small ones are sent to a special separator, where they are captured. This technology is quite effective, as it allows the use of a multi-stage filtration system with a minimum of purchased consumables. However, for a vacuum cleaner with an aqua filter to operate, it may require a large amount of clean water, which is not always possible to provide under construction site conditions.

It should be said that there are no industrial vacuum cleaners without a filter at all. It is always necessary to carry out “biological” air purification. The fine filter periodically becomes clogged, as a result of which productivity drops significantly and a forced stop is necessary. Manufacturers offer various ways to solve this problem. The simplest thing is to manually clean the filter element with a special comb; it does not need to be dismantled (RGS ONE22). Advanced models, using a targeted pneumatic shock, are able to give their filterer a “shock” (Karcher NT 35/1). The operator presses a button and a powerful air flow passes through the filter in the opposite direction. As a result, the suction power remains stable, the continuous operation time increases, maintenance becomes cheaper, and the service life of the vacuum cleaner is extended. And you don't have to take anything apart!

Many models of construction vacuum cleaners combine various filtration methods. They can simultaneously be equipped with a container, bags, and various filters (nylon for disposable dust collectors, corrugated for a container, polyurethane for removing liquids). The user can only choose the right kit for certain conditions. Using filters and dust collectors correctly is the only way to avoid going broke on expensive consumables.

Construction vacuum cleaner layout

We have sorted out the suction part, now I would like to discuss with you the issues of design, ergonomics and configuration of industrial vacuum cleaners. We are not interested in stationary models - we only look at what can be dragged onto the site. The layout of most vacuum cleaners is more or less similar. Body, wheels, handles, hose, cord, controls - that's it in a nutshell. Now, in order.

An industrial vacuum cleaner is designed to collect a large amount of debris, so the volume of the container of such a device can reach 50-60 liters (Sparky VC 1650 MS). It is clear that the case in this case will not be small. If in a workshop the volume of a waste bin is larger, the better, but for a builder-finisher the size matters. As a rule, we strive for light weight and compactness, naturally, within reason. And is a 50-liter bag really necessary if it is not recommended to fill it more than halfway with heavy garbage (otherwise you simply won’t be able to pull it out). That is why small models that can be easily transported appear. Those who like to work without getting tangled in network cables consider portable cordless vacuum cleaners, for example, the Milwaukee V 28 VC (container volume 9.6 liters, weight 5.4 kg), to be the apotheosis of technical thought.

Interestingly, the manufacturer does not always use the large housing size wisely; the cylindrical pleated filter often takes up too much useful space. It is a good rule of thumb to remove the filters from the tank to the “head” of the vacuum cleaner, or to use flat cassettes, which makes it possible to free up space inside the tank.

Taking into account difficult conditions, many manufacturers make the bodies of their devices from durable materials - steel, aluminum, stainless steel, brass, various alloys (Hitachi WDE 3600). Springy “bumpers” may be located on the protruding parts. Plastic is considered too fragile for making tank walls, although many companies prove the opposite.

Be that as it may, the vacuum cleaner needs to be moved, preferably without leaving grooves on the new parquet. To do this, the developers came up with swivel “piano” wheels, which are also found on household models, only stronger. For heavier units (over 10-12 kg), special frame trolleys with rubberized wheels of different sizes are being developed (Sparky VC 1650 MS). Don’t forget, you also have to roll a decent weight of garbage, so the unit is subject to extremely serious requirements in terms of reliability and functionality. By the way, it is very welcome to have a convenient foot brake, at least for one wheel (Flex S 47).

For mobility, you need functional handles for carrying and transportation; in this regard, there are a lot of options: top, side, retractable - it is advisable to test their functionality before purchasing.

Most construction vacuum cleaners are designed in such a way that they can be connected to tools that generate large quantities of dust. Mechanically, such integration is ensured by all kinds of adapters (adapters) that are suitable in diameter to the outlet pipes of the equipment. Also, on the body of an industrial vacuum cleaner there is usually a power socket that can withstand a load of over 2 kilowatts, from which the tool is actually powered. In particularly technologically advanced vacuum cleaners, communication between two units can be carried out automatically (Makita 446L). By turning on the "Start" button, for example on a sander, we simultaneously activate the vacuum cleaner. After the tool stops working, the “cleaner” collects garbage for a few more seconds and also turns off.

The construction vacuum cleaner has systems that protect the power plant from overloads (AEG RSE 1400). The unit can automatically turn off when it overheats or when the reservoir is full during wet cleaning (DeWalt D27900). There is sometimes an LED indicator on the housing that indicates whether the hose or filter is clogged or whether the dust container is completely full. Naturally, it is always possible to select the suction strength (Kress 1200 NTX EA), and the regulator can also be located on the suction pipe.

Many manufacturers configure their units with additional water drainage pipes, which greatly simplifies maintenance. On the body there are sometimes nests for storing equipment, and even elements for stationary fastening of a large crevice nozzle (helps when cleaning large flat areas). An undoubted advantage is the presence of a long and reliable power cord, because it often powers power tools that work in tandem with a vacuum cleaner.

When choosing an industrial vacuum cleaner, you should definitely pay attention to the completeness of its configuration. Of course, a lot can be purchased separately, but all consumables and additional accessories are not cheap. Typically, the basic package includes a long hose (up to 7.5 meters), an adapter elbow, several nozzles, a pipe, an adapter for a tool, a container, a set of filters and dust collectors (Bosch GAS 25).

Let's sum it up

So, we have several cars in mind. The first thing we pay attention to is the type of pollution we will fight. Next, you need to decide on the performance of the vacuum cleaner and its continuous operation time. The next point will be to select a unit based on the filtration system. Then, regarding the device you like, we find out (in a complex) the cost and availability of spare parts and consumables. We are interested in the possibility of authorized service and warranty service. If all the pieces of the puzzle fall into place, the brand name is familiar, and the price tag suits you, you can safely head to the checkout.
