Bagless construction vacuum cleaners: features, types and tips for choosing

Often there is a production need to clean up large premises: workshops, construction sites, business centers, concert halls. Vacuum cleaners for industrial and construction purposes effectively help to deal with many types of contamination. These machines are capable of solving complex complex problems, but before purchasing a machine, it is recommended to understand the specifics of a particular model.

A construction bagless vacuum cleaner differs from a household unit in increased power. Industrial designs are differentiated into two types:

• technical and industrial;
• industrial.

There are many bagless models that are designed to do a wide variety of jobs. Bagless construction vacuum cleaners for dust collection are very popular not only in production, but also in everyday life.

Such units function due to the occurrence of thrust, which is caused by a pressure drop. Microparticles are sucked in through a special hollow device that resembles a pipe in shape. At its end there is a nozzle in the form of a stiff brush, which allows you to scrape off dirt from any surface. Microparticles enter a special container, passing through a filter system, and the purified air is returned to the room. Such models are equipped with a vibration cleaning function.

Not all vacuum cleaners can perform universal cleaning functions. For example, the removal of explosive substances (coal and aluminum dust) can lead to fire or even explosion. The explanation is simple: a vacuum cleaner is a power tool in which rotor brushes are present, they generate sparks.

There are also models that are capable of wet cleaning. Such machines have a different container format, they contain a washing solution. Wet cleaning is most often done in conjunction with dry cleaning. Also, during such work, various filters are actively used. They are:

• water;
• cyclonic;
• fine cleaning;
• complex.

In some cases, during cleaning the premises, additional connection of any unit is required. For this there is a socket on the body of the construction vacuum cleaner, to which various devices can be connected.

Contamination can be very different, and some of them are difficult to eliminate. Various filter systems, which are used while the vacuum cleaner is running, help to cope with complex contaminants... Aquafilter (container with washing liquid) is one of such effective elements. An air stream containing microparticles passes through it.

Units with cyclonic filters are also used on construction sites.that can eliminate any type of pollution.The disadvantage of such devices is that they do not "capture" microparticles; therefore, it is necessary to additionally install fine filters. The combined work of the two types of filters allows you to cope with almost any contamination. At the same time, the cost of the devices can be relatively low.

Most often, for normal operation of the device, a power of 1.5 kW is sufficient, while the suction power should be at least 210 W. With such indicators, it is possible to process both small objects and impressive areas.

When buying a vacuum cleaner, you should definitely focus on the following parameters:

• power;
• the volume of the container;
• cord length;
• additional functionality;
• warranty periods;
• the ability to carry out service.

Separately, we can single out models with a very high power (up to 7.5 kW), the volume of air passing through these "monsters" is over 120 liters in 60 seconds. Trash containers in such models are usually enough up to 25 liters, with such a volume, any pollution in a medium-sized room can be eliminated.

Many devices have a power regulator, which is convenient when cleaning various dirt, while significantly saving electricity. Vacuum cleaners, which have containers instead of garbage bags, have indicators showing their fill level. The principle of operation of such devices is based on the functioning of a float valve.

Rating of the most popular models of bagless vacuum cleaners for industrial and construction purposes:

• Makita VC25122;
• EinHell TH-VC 18200 S;

Cleaning with these devices is carried out both wet and dry, the volumes of dust collectors on such devices are also rather big (up to 25.5 liters). The machines have an additional "input" through which the following units can be connected:

• turbines;
• wall chaser;
• jigsaw;
• electric chisel and others.

Of the weak qualities of the unit Makita VC2512 it can be noted that there is no "blowing" function. The device is compact, weighing only 7.8 kg. The set includes a set of containers. This model is made at factories of the European Union, which a priori speaks of a high-quality assembly. There are many service centers of this brand in our country, and if necessary, the tool will be easy to repair.

TH-VC 1820 S - a versatile unit that can clean any plane from dirt and dust accumulations. The power in such a compact device is pleasantly surprising - 1.25 kW. Waste is collected in a large 20 liter container. It is also possible to carry out wet cleaning with this vacuum cleaner.

There is a socket on the body, which allows the synchronous connection of various devices.

The container is made of "stainless steel", easy to clean. During operation, any electric tool can be connected to the unit. Additional benefits:

• drain neck;
• auto-twisting power cord;
• handles are present.

The company has established itself in the Russian market from the very best side. Construction vacuum cleaner Bosch GAS 20 (weight 5.9 kg) is not cheap, but this model is reliable and efficient. It has comfortable handles and casters. The socket on the body allows you to connect any electrical device.

The advantages of the Bosch GAS 20 model:

• original look;
• durable body;
• well working mechanisms;
• it is possible to do wet cleaning;
• high efficiency;

Until recently, Japanese and German vacuum cleaners were considered the best vacuum cleaners in Russia, but the development of domestic industrial production in Russia is making its own adjustments. Has become popular in our country model PU-34/1202, which is produced by the well-known company "Interskol". This model has the most complete equipment, as well as a complex filter with vibration cleaning. The engine is only 1.21 kW. There is a dual-mode power setting.

The model stands out for its optimal combination of price and quality. TTX machine has the following:

• container capacity - 33 liters;
• cyclone filter;
• hydraulic protection against excessive loading of the container;
• high suction power (62 hp).

In the price / quality category, the Russian-made Soyuz vacuum cleaner showed itself well. The car costs only 5.5 thousand rubles. Very popular model PSS-7322... At a construction site, it is difficult to find something better than this vacuum cleaner.

Positive traits:

• high power;
• ease of use;
• performance.

To choose the right vacuum cleaner, you need to understand how effectively it can remove dirt of a very different nature.

Dust is differentiated into the following types:

• safe dust - these are microparticles of substances such as chalk, villi, earth;
• medium hazard - alkali, radioactive materials, metals;
• high hazard dust Are carcinogenic substances, radioactive materials, heavy metals, phosphate fertilizers, etc.

To eliminate the latter type of dust, powerful special equipment and personal protective equipment are required.

To find the right device that will optimally meet your needs and requirements, you need to:

• determine on what principle the vacuum cleaner works;
• what power a particular model has;
• what types of garbage this or that vacuum cleaner specializes in;
• bag volume;
• availability of additional functionality.

If you need to remove garbage on an industrial scale every day, then it is more rational to buy a vacuum cleaner from the manufacturer Makita, Bosch or Interskol. Such machines can operate for many hours, they have good power, which allows them to process up to 200 square meters of high quality within an hour. Each unit is supplied with a variety of attachments, which is important to consider when choosing.

For the blowing function to work, certain accessories are required, so you should check that they are available when purchasing your machine.
