Industrial (technical) vacuum cleaners in industry, their equipment and functions

Do you really need an industrial vacuum cleaner? Is it worth the money?

Many people do not understand the difference between industrial and home vacuum cleaners, especially since they are very similar in appearance. The development of modern technologies has led to the fact that the design of traditional dust collection devices has become closer to more professional models. However, this is perhaps the only similarity between these types of vacuum cleaners. The “stuffing” of industrial devices is completely different.

We’ll talk about the technical stuff later, but now we’ll look at the advantages of industrial vacuum cleaners. Why is buying or renting such a device more profitable than a regular home one?

Firstly, industrial vacuum cleaners are named so for a reason. These are professional tools for removing dust and dirt from any surface, even if these very surfaces are nothing but “bare” concrete. Such equipment allows you to effectively get rid of not only dust, but also metal and wood shavings, loose paint, varnish, to remove fungi, mold and other substances and impurities that arise in homes, warehouses, production shops, workshops, factories and during various types of construction and repair work. With such vacuum cleaners, unlike ordinary household ones, you can even clean paths around the house!

Secondly, industrial vacuum cleaners are much more powerful than conventional devices. This is necessary in order to get rid of, among other things, larger and heavier elements than a piece of paint and plaster (for example, pieces of concrete and stones). Moreover, they have more durable bags (and there are models without bags), so you don’t have to worry about the operation of the device if you accidentally vacuum up, for example, several screws or nails.

Today, the range of manufacturers and models of such vacuum cleaning equipment is quite large. They all differ from each other in various parameters (power, class, container capacity, etc.), as well as in the nature of the application. Some models of professional vacuum cleaners are equipped with special attachments and accessories for removing dirt and dust in particularly difficult cases and hard-to-reach places.

Therefore, the choice of a suitable industrial vacuum cleaner depends mainly on the nature of current and future work, additional options, as well as the individual preferences of the user. But still, the main division of these devices is into 2 types: vacuum cleaners with bags and without bags. Let's look at their differences in more detail.

Main selection criteria

Before purchasing an industrial vacuum cleaner, make a list of the functions that the working device must perform. After this, it will be easier to choose the right model, and you will not overpay for unnecessary options.

Dust class and dust container type

Knowing the class of dust and dirt is very important. The class of the vacuum cleaner depends on what kind of dust needs to be collected. Next, we will consider the main designations that can be found in the instructions for cleaning equipment.

Decoding letter markers:

L – the device is used for dry cleaning of ordinary dust – low-hazard. For example, from clay, concrete, paint, varnish, etc.
M - the device copes with wood and concrete debris - medium hazard class. Devices with this class are also used for cleaning at power plants.
H – the unit cleans from highly hazardous dust with pathogenic and allergenic bacteria. For example, fungus, microbes, fertilizers, caustic dyes.
ATEX - industrial vacuum cleaner is used to clean explosive and flammable dirt - the highest hazard class.

Waste with a high degree of fire hazard can only be removed by special industrial devices.

By connecting an electrical appliance to a vacuum cleaner, it is possible to avoid the formation of large amounts of dangerous dust, as well as keep the workplace clean

Depending on the purpose for which the equipment is needed, the type of dust collector is selected. So, among the most common are the following types.

Fabric bag. It is reusable, so accumulated debris must be shaken out. They are made from thick non-woven fabric. If the fabric is double or specially impregnated, then it can trap even fine dust; if another fabric is used, then only large particles.

Disposable paper bags can be thrown away once they are filled and you will not have to come into contact with dust. They collect dust particles no smaller than 0.3 microns in size.

You should not collect debris in such bags that can damage them, such as glass, stones, fragments of materials, etc., otherwise debris may get into the engine, which will lead to breakdown.

Containers are used in units with a cyclone filter. They are easy to clean, but, unfortunately, such models are noisier. They are perfect for large industrial waste, liquid mud and water.

The rating of the best construction models without a bag is presented in this article.

Experts recommend using a bag in addition to the container, because in this way you can extend the life of the main filter and collect fine dust.

The aquafilter is considered the most effective, because it “picks up” even the smallest dust and is not afraid of large waste and glass. However, such filters are not installed on large vacuum cleaners.

Design and power of equipment

As a rule, the steel body is coated with a special durable paint. The device protected in this way receives additional noise insulation.

Also, the method of movement also plays an important role, because industrial units are quite heavy.

Industrial vacuum cleaners, in addition to excellent technical characteristics, are heavy. These models are equipped with wheels for greater ergonomics.

The dimensions and, to a certain extent, the amount of garbage collected depend on the volume of the container and dust collector.

If we talk about suction power, then a number exceeding 400 W is considered optimal. The higher the indicator, the better the quality of cleaning. Please note that before purchasing, you should check whether the electrical network can withstand the high load.

The cleaning efficiency depends on the capabilities of the motor. If you need a device for cleaning small rooms and non-hazardous dust, then focus on the figure from 2 kW.

If there is a need for an industrial model that will uninterruptedly clean large surfaces, then the power should be more than 3 kW.

The dimensions are affected by the size of the waste tank, engine, presence of turbines and filters. Choose priority features so you don't overpay for unnecessary features

There are vacuum cleaners with two or three motors, which allows for less wear and tear on the mechanism. There are three-phase models and those that run on battery power. The latter are limited by battery life.

Motor washers are equipped with air insulation to prevent moisture from reaching live parts. Graphite brushes fail much faster than the engine they are part of. Therefore they must be checked and replaced if necessary.

When cleaning large particles of dust, shavings, splinters or hazardous debris, be sure to use a protective mask, gloves and, if necessary, headphones

Based on these basic technical indicators, you can easily select a suitable industrial vacuum cleaner.

Additional equipment characteristics

Most often, additional functions do not affect the quality of cleaning, but make life much easier for users. Let's consider the most significant of them.

The vacuum cleaner should be easy to use. Design on wheels, long cable, working hose and several attachments

Some models have a separate socket on the body for connecting power tools. This allows you not to be distracted while performing complex work.

Special adapters and splitters are also useful, thanks to which you can simultaneously connect several dust-generating devices or hoses. Especially if there is a need to connect devices from other manufacturers to the vacuum cleaner.

When choosing the right model, also pay attention to the length of the hose and what material it is made of.

It is worth paying attention to protecting the engine from overheating if the device is used in large workshops or in production. If there are power surges in your area, you should install a fuse or relay to prevent expensive equipment from breaking down.

Thanks to the vacuum control function, users have the ability to change the suction strength by controlling the pressure.

Light notification about the filling of dust collectors, the condition of the motor, filters, and possible breakdown will also be a nice addition.

If you purchase a washing device or a combined device (wet + dry cleaning), then pay attention to the drain neck. Now, to clean the tank with dirty water, you just need to unscrew the drain and drain the water.

A washing vacuum cleaner will quickly get rid of spilled water or oil. In such models, the motors are reliably insulated to avoid short circuits and injuries.

Whatever device you choose, remember that any equipment needs timely cleaning and careful maintenance.

Which industrial vacuum cleaner to choose: bagless or bagless?

In professional vacuum cleaners without a bag (the so-called “cyclones”), all dust and dirt, instead of a bag, goes into a special built-in container. These devices operate on the principle of centrifugal force and a specially designed cyclone system, which removes harmful dust from the air using a centrifuge method.

Bagless vacuum cleaners are considered more durable and stable. Devices of this type are characterized by constant and high suction power throughout the entire service life of the device. The same cannot be said about vacuum cleaners with a bag - in them this parameter quickly decreases as the bag fills with dirt, which makes the device less effective or even ineffective after several hours of operation. In practice, this means that each time you have to change the bag more and more often, even before it is completely filled, and so on several times during the cleaning process.

However, buying an industrial vacuum cleaner with a cyclone system just to save money on cleaning bags is a serious mistake. Bagless cyclonic vacuum cleaners have their own “weakness” - dust filters, which break down faster and are more expensive than those installed in conventional vacuum cleaners with a bag. And cyclone vacuum cleaners themselves are much more expensive.

Another factor to consider when choosing a bagless industrial vacuum cleaner is the price and manufacturer. Devices that are too cheap and untested often turn out to be of poor quality. The efficiency of cheap vacuum cleaner models leaves much to be desired, to the point that some types of dirt and dust can be returned back into the room, and filters become clogged faster. Among the disadvantages of this model of industrial vacuum cleaners, the need to regularly clean the chamber should also be mentioned.

Is it worth paying extra for bagless cyclone devices? To be fair, we note that simple operation of industrial vacuum cleaners with a cyclone system is an order of magnitude cheaper than industrial vacuum cleaners with bags. Another undoubted advantage of these models is their greater efficiency and durability.

Operating principle and rules for choosing a construction vacuum cleaner

We probably won’t open America to anyone by saying that a construction vacuum cleaner works the same as the most ordinary household construction. There is a fan inside the device, which will be driven by a special motor. During operation, air, along with dust and larger inclusions, is directed into this low-pressure zone. Subsequently, it passes through the filter elements, remaining in them, and the purified air is directed back into the room through the outlet.

In this case, a construction vacuum cleaner can be fixed directly in the work area so that there is a minimum amount of dust, it can also be connected to another tool, and can be used as a standard vacuum cleaner after completion of the work.

How to choose a suitable industrial vacuum cleaner?

When looking for a suitable bagless vacuum cleaner, pay attention to its parameters. If the equipment packaging does not contain information about the effectiveness of the device, it is better to refuse such a purchase.

What parameters are we talking about? For example, suction power. The higher this parameter, the better the air circulation in the chamber of the device, which is necessary for accurate absorption and accurate filtration of impurities. The suction power directly depends on the motor power, which should be at least 1200 W, and even better, 1600-1800 W. Everything is simple here: the greater the power of the vacuum cleaner, the higher its performance and efficiency.

Let's take, for example, a bagless industrial vacuum cleaner from the Karcher brand, which is very popular among builders. It has high suction power and is equipped with a multi-stage filter system, making it suitable for use in the most difficult conditions. With such a vacuum cleaner, you can effectively remove dry impurities, pieces of varnish and paint, and even spilled liquids from the floor.

In addition, these devices are made of highly durable and shock-resistant housing. Some models are also equipped with automatic filter cleaning systems and the ability to remove not only dirt, but also harmful dust. Thanks to these indicators, Karcher vacuum cleaners are truly universal devices.

Among other popular devices among developers, we note the industrial vacuum cleaner from Bosch. The products of this German brand have a long service life, and the vacuum cleaners themselves can handle both “dry” and “wet” work. In addition, Bosch vacuum cleaners are very powerful. High suction power means that with such a device you can cleanly remove dust and dirt not only from the floor of the house, but also from any other surfaces. An additional advantage of the product is its durable wheels, thanks to which you can quickly and easily move the equipment to the desired place and room, and even roll it around the site.

One of the most practical devices of this type is the bagless industrial vacuum cleaner with socket 1420. It is equipped with a special socket to which we can connect any electrical tool, such as a sander. The special mode allows you to control the vacuum cleaner using a power tool and the two devices work together, so you don't have to constantly be near the vacuum cleaner to turn it on and off.

Choosing an industrial vacuum cleaner: results

Purpose and scope of application

First, you need to decide where and how the industrial vacuum cleaner and what it will have to do. If you need to remove dry dust and the work will be periodic, then, of course, an entry-level model is suitable. For a large volume of work and the amount of material collected, a three-phase vacuum cleaner is more suitable.

When there is a sufficiently powerful network, you can use a pneumatic vacuum cleaner; such vacuum cleaners have a low noise level and high vacuum, and they are also extremely reliable in operation.

In cases where it is necessary to collect liquid along with metal shavings, special vacuum cleaners of the KOIL series are used. The benefit of such models is that the collected liquid can be reused.

In hazardous industries, vacuum cleaners with an increased filtration system are used - these are units that can be equipped with a double system of class M and HEPA filters.

Vacuum units with ATEX marking are used for work in potentially explosive environments.

The main criteria you should pay attention to when choosing a vacuum cleaner

The scope of application will be determined
Filtration level
Performance (discharge and air flow)
Degree of protection
Design of the vacuum cleaner (for example, stainless steel when working with corrosive materials)

Industrial vacuum cleaners of cyclone type. Prices

The cost of bagless vacuum cleaners varies widely. Cheap Chinese models can be bought for only 4000-5000 rubles, while professional vacuum cleaners made in Germany will cost no less than 18-20 thousand rubles. The price of an industrial vacuum cleaner also depends on the type of filter, engine power and additional equipment. So, for example, professional vacuum cleaners with a power of 1800 W from Karcher or Bosch will cost at least 25 thousand rubles.

As we noted above, in this class of devices, a lower price almost always means less engine power and a lower class. This means that such equipment, despite the fact that it suctions dust well, cannot always cope with removing larger and heavier dirt and debris from the floor.

Is an industrial vacuum cleaner suitable for home use?

Professional construction vacuum cleaners are useful not only at construction sites, but also for traditional house cleaning. However, unlike conventional vacuum cleaners, in this case, high power is more of a minus than a plus.

Experts do not recommend using such equipment to clean the house after repairs or finishing have been completed. The fact is that industrial vacuum cleaners are designed mainly for rough cleaning of dust and dirt, and their equipment, attachments, brushes and accessories can inadvertently damage parquet or scratch tiles. Such equipment is ideal for use in the following stages:

construction sites;
repair;
rough finishing;
pre-finishing and final finishing;
at stages when the floor in the house has not yet been laid (not installed).

However, this does not mean that an industrial vacuum cleaner will not be useful in your home after the renovation is completed. It can be useful when doing some housework. Eg:

remove shavings from the workshop floor;
remove from the floor pebbles and pieces of crushed stone that have fallen from the wheels in the garage;
remove ashes from the fireplace and much more...

Then the question arises: which industrial vacuum cleaner would be the best solution for the home? And here we come back to power again. If you need a professional vacuum cleaner for regular home use, it is better to choose low-power models: 1000-1200 W is enough. With such motor power, the equipment can effectively cope with almost any type of contaminant.

Which model will be better for home: with a bag or without a bag?

If you have small children and allergy sufferers in your home, choose cyclone devices without a dust bag. In other respects, both types of vacuum cleaners are equally effective.

When purchasing a professional vacuum cleaner for your home, be sure to pay special attention to the accessories and attachments that the model you are interested in is equipped with. Ideally, they should be as close as possible in form and functionality to those found in traditional vacuum cleaners. The right brushes and attachments will allow us not to worry about the device scratching parquet, tiles and other finishing elements in our home.

For home use, an L class industrial vacuum cleaner is sufficient.

Types of construction vacuum cleaners

Within the category, construction vacuum cleaners can be divided into several types:

For dry cleaning. Such models are the simplest - they differ from ordinary household ones only in increased power. Suitable for removing cement, lime and gypsum dust from the premises.

“Dry” construction vacuum cleaners are equipped with reliable filters for the smallest particles
To collect liquid. The units are capable of sucking up not only dry debris, but also spilled water. A special feature of the models is the separation of air flows for dust suction and engine cooling.

Washing vacuum cleaners are especially convenient for use in warehouses and large construction sites
For fire hazardous waste. They are equipped with an electric motor without graphite brushes and do not generate sparks during operation. Can collect wood and coal dust, zinc and aluminum powder.

Vacuum cleaners for flammable waste are used mainly in production
For hot waste. Models can suck up heated metal shavings and other materials before they cool down.

Heat-resistant vacuum cleaners are used in factory floors

For home renovations, construction units are usually chosen to collect dust and liquids. Models with additional capabilities are rarely in demand.

Which industrial vacuum cleaner to choose for the garage?

Buying an industrial vacuum cleaner for the garage is the best solution, since such devices can remove almost all types of dirt and dust that accumulate in the garage, even in hard-to-reach places.

If your garage is clean and heated, a “home” model of a professional vacuum cleaner will be enough; if the garage is unheated and built separately from the house, it is recommended to choose more powerful models with which you can effectively remove pieces of snow, ice, dirt and pebbles from the garage floor . We are talking about devices with motor power in the range from 1200 W to 1400 W and class L or M.

Another important parameter is wet cleaning. When choosing an industrial vacuum cleaner for the garage, it is recommended to pay attention to models for both dry and wet cleaning. Thanks to this equipment, in most cases, you don’t even have to wash the floor in the garage - the vacuum cleaner itself will clean the floor of both soot and various oil stains.

Which industrial vacuum cleaner to choose for cleaning plaster?

Plaster is one of the most difficult finishing materials to clean. To get rid of traces of it, it is better to choose an M-class industrial vacuum cleaner. Such equipment has proven itself to be effective in absorbing dust, carpentry waste, aggregates, and paint residues.

The engine power can be any, in this case it is better to pay attention to the class of the vacuum cleaner. Of course, the H class model will also cope with cleaning plaster from floors and walls. Such devices allow you to clean your home from other types of construction waste: cement, plaster, asbestos, lead and even mold.

Which industrial vacuum cleaner to choose for wall shredding?

Chipping concrete or brick walls always involves a lot of dust. Therefore, when choosing a vacuum cleaner for cleaning in such cases, it is recommended to pay attention to class L devices with special attachments for cable ducts and grooves. They make it much easier and easier to clean cavities in the walls.

There are also so-called special vacuum cleaners that work in synergy with hammer drills and grinders and automatically suck up dust. The rotating discs cause a lot of dust to be generated during its operation, so this tool is usually equipped with ends that allow it to be connected to an industrial vacuum cleaner.

In this case, you should choose an industrial vacuum cleaner equipped with an outlet for power tools. This solution ensures that both devices work synchronously, so you don't have to inhale a lot of dust, which is also harmful to our lungs.

Industrial vacuum cleaners. Which power is better?

The motor power determines the suction efficiency of the device, and it should be in the range of 1200 W to 2000 W, depending on what kind of work the vacuum cleaner will be used for. If you plan to use it also while cleaning the house, it is better, on the contrary, to choose less powerful models.

You should also make sure that he has additional equipment. All suction nozzles and telescopic tubes make it easy to remove stains, dust and dirt, even from hard-to-reach places.
