Choosing an industrial vacuum cleaner for concrete dust

The formation of concrete dust accompanies any repair and construction work in which cement is used, and requires immediate measures to be taken to remove it. Unfortunately, ordinary household vacuum cleaners are not able to cope with specific construction dust, therefore, powerful industrial vacuum cleaners are used for such purposes.

Structurally, an industrial vacuum cleaner for collecting concrete dust is not much different from its household counterpart. It is a networked device consisting of a robust housing, an electric motor, an air turbine, a brush, several hard nozzles and a dust collector. The only significant differences are the presence of a powerful filtration system that effectively traps fine dust particles and does not let them back into the room, and the presence of an electric motor cooling system.

The principle of operation of industrial designs is also similar to the principle of operation of home models and consists in the following: A running electric motor drives a turbine, which, with the help of a long hose and various nozzles, sucks in concrete dust, takes it into a dust collector and settles it there. Air entrained with dust passes through the filter system and leaves the unit in a clean state.

However, if there are no fundamental differences in the design of household and industrial models, then their operational properties and technical parameters differ quite strongly. So, industrial designs have higher power and productivity, are capable of long and continuous operation, are distinguished by a high noise level and can perform wet cleaning and even dry cleaning. A feature of some models is the ability to work synchronously with a construction power tool, which allows you to remove dust directly in the process of its formation.

This becomes possible due to the presence on the body of the vacuum cleaner sockets and special nozzles and adapters that connect the hose to the working tool through the branch pipe. As a result of the synchronous operation of both devices, the spread of debris becomes minimal and the cement dust is absorbed by the vacuum cleaner, barely having time to form.

The field of application of industrial vacuum cleaners for collecting concrete dust is quite wide. The units are indispensable for the construction and dismantling of walls, ceilings and partitions, for drilling holes for water supply, sewerage and gas networks, for sawing concrete structures and for cleaning cement substrates from the remnants of old decorative coatings such as paint or plaster.

Professional vacuum cleaners for collecting concrete dust are divided into bag and bagless models. The former are equipped with capacious reusable or single-use bags made of paper or fabric.

• Cloth bags are considered the most practical type and are distinguished by low cost and wide consumer availability.The models can be used many times and, after full filling, are simply removed from the vacuum cleaner and shaken out. For the manufacture of such bags, durable synthetic fabrics are used, which gives them a sufficiently long service life and eliminates the need for frequent replacement. Along with the obvious advantages, fabric bags still have disadvantages. So, some bags have a single-layer design, which is why they can let a small part of dust particles back into the room.
• Paper models, unlike fabric ones, they completely trap concrete dust and prevent even the slightest leakage. Thanks to this, the quality of cleaning increases and the air in the room becomes cleaner. Paper bags are disposable and, once full, are removed and discarded. The disadvantage of such models is the risk of violating the integrity of the package when collecting dust with inclusions from broken glass or small pebbles.

Bagless vacuum cleaners do not provide for the presence of a cloth or paper bag, and debris accumulates in bulky receptacles. Storage tanks are of two types: with the Cyclone system and with an aquafilter.

• Models with the "Cyclone" system represent a large group of units and function as follows: the pump sucks in concrete dust and feeds it through a hose into a special storage device. There, under the influence of centrifugal force, dust particles settle to the bottom of the container and remain there until it is cleaned. In addition to collecting concrete dust, container models are used to remove moistened debris and liquid pollution. The disadvantage of the "Cyclone" system is a strong hum during operation. This is due to the fact that during the settling process, the debris hits the walls of the compartment and creates a lot of noise.

• Models with aquafilter appeared relatively recently, but were immediately appreciated by their merits and became widespread. The essence of the work of such a dust collector is as follows: air with dust particles passes through a container with a liquid, as a result, the dust remains in the water, and the purified air comes out. In this case, especially fine particles are taken into the separator and deposited in it.

When buying an industrial vacuum cleaner for collecting concrete dust it is necessary to pay attention to a number of technical parameters.

• Power is one of the defining characteristics and affects the performance and suction power of the device. So, if the model is planned to be used at construction sites, then it is better to choose a unit with a capacity of 3 to 7 kW. Such samples are able to work without stopping for quite a long time and can suck in about 70 liters of concrete dust per second. The rotational speed of the working shaft in engines of this power often reaches 30,000 rpm.
• Volume the storage tank of industrial models varies from 20 to 100 liters and is selected according to the expected load. So, if a large storage device is not necessary, then it is better to choose a compact, inexpensive model. This is due to the fact that with an increase in the volume of the dust collector, the weight and dimensions of the unit itself increase, and if the vacuum cleaner is used in small occasional works, then there is no point in acquiring a heavy and cumbersome model.
• Body material should also be selected individually. For intensive use, it is better to buy a unit in a shockproof steel case, equipped with an additional bumper. Such models are not afraid of accidental falls and collisions with obstacles.
• Additional functions are a pleasant bonus and greatly simplify the use of the unit.These options include a socket on the body of the vacuum cleaner, designed for synchronous connection of power tools, for example, grinders or electric drills, as well as an automatic filter cleaning system. Helpful options include overheating protection and an indicator light to indicate when the bag is full or the hose is blocked.
• Mobility vacuum cleaners are especially important when working on weak substrates, when there is a risk of damage by heavy and bulky units. So, for problematic fragile floors, lighter models equipped with swivel wheels are suitable, while on stable concrete surfaces, you can use powerful samples equipped with trolleys on rubber wheels.

Today, a huge number of industrial vacuum cleaners are produced that can collect concrete dust. Among them there are both expensive eminent brands and little-known budget samples. Below are the most popular models from the largest online stores.

• Professional Italian model "IPC Soteco Tornado 633 Inox" It is equipped with an electric motor with a power of 3.5 kW and is capable of operating from a voltage source of 220 V. The dust container has a capacity of 78 liters and is made of stainless steel, and the mobility of the unit is provided by a mobile trolley equipped with swivel wheels. In addition to work in the construction industry, the device can be used for cleaning hospitals, offices and sales areas. It easily handles all types of fine dust, as well as shavings, dry debris and liquid dirt.

• Korean model "Messer DE 25" equipped with a 1.2 kW motor, a cloth dust bag and is intended for dry cleaning only.
