How to choose the right construction (professional) vacuum cleaner? Overview of important features

Everyone who has taken part in repair work at least once knows how difficult it can be to clean the building from construction dust..

With this task can handle industrial vacuum cleaner, which, unlike the usual vacuum cleaners, unaffected by abrasives and metal particles.

This technique is useful both for production and for a home whose owners like to do repairs on their own.

Purpose of construction vacuum cleaners

Working in such conditions may face serious problems:

• dust is a strong allergen;
• visibility deteriorates and the quality of operations is reduced;
• the cutting tool in dusty rooms wears out faster;
• many finishing works can only be started after all dust has been carefully removed.

Large construction debris is removed manually, but small particles are more difficult to deal with.

It is impossible to achieve a high-quality result with brooms and brushes; in the process of sweeping, a cloud of dust rises into the air.

A household vacuum cleaner will also not be a good helper - it does not have enough power to draw in heavy fragments and can throw harmful particles into the air.

In addition, abrasives will quickly render a device not designed for such an impact unusable.

Its branch pipe can be fixed in the working area for the timely removal of contaminants or connected to a power toolequipped with a special adapter.

The unit is also suitable for cleaning the premises after completion of work.

Types of professional vacuum cleaners

There are two types of professional vacuum cleaners:

1. Industrial — are intended for operation in the conditions of production.
   Able to withstand heavy loads.
2. Construction - suitable for cleaning after minor home repairs.

Varieties of models by type of cleaning

Professional vacuum cleaners divided by purpose, that is, by the type of pollution with which they can cope.

For dry

It is used to collect building dust.

For dry and wet

Similar devices collect not only dust, but also spilled liquids.

detergents

Such vacuum cleaners are also suitable for collecting dry dust, but their main purpose is wet cleaning public places and industrial premises.

For cleaning explosive materials

The electric motors of these models do not have graphite brushes that can lead to the formation of sparks.

A mandatory requirement for these devices is the ability to change the air flow rate.

Vacuum cleaners that are suitable for cleaning explosive substances and materials are the most expensive.

They are are used exclusively in highly specialized enterprises.

Criterias of choice

First of all, you should pay attention to the main parameters of the devices.

Operating conditions

It is necessary to think about how often and for what purposes the unit will be operated. All pollution is divided into several classes:

1. L - minimum danger.
   A standard nylon filter is suitable for collecting most construction waste, retaining about 99% of dust.
2. M - medium degree of danger.
   To clean up waste left from the processing of metals, concrete and wood, air flows must pass through several filters that ensure the retention of 99.9% of contaminants.
3. H - high degree of danger.
   Inhaling even small amounts of carcinogens such as asbestos or lead, as well as bacteria, fungi and mold spores, can be harmful to health.
   The technique must ensure the collection of 99.995% of contaminants.
4. ATEX are wastes requiring special protection against ignition and explosion.
   The electrical safety of the vacuum cleaner must be at least IP.

Power and performance

For professional devices this indicator can reach 7 kW, which guarantees a performance of 60 to 100 l / s.

There are units operating both in standard mode and in high power mode.

This allows you to save energy when high performance is not needed.

Vacuum degree

The vacuum created by the fan of the device, determines the strength of its absorption.

For professional models, this parameter varies between 17-250 millibars.

The greater the degree of vacuum, the heavier debris particles can be captured by the device.

Therefore, this indicator is more important for evaluating the efficiency of equipment than power consumption.

Dust container volume

If there is no need to clean up impressive volumes of garbage every day, you should not strive to choose a model with a maximum capacity.

An increase in this parameter inevitably leads to a heavier unit and its bulky dimensions.

The maximum volume of the dust collector of equipment operated in large-scale production is 100 l.

This saves time emptying the trash can during the shift.

Vacuum cleaner body

For the manufacture of housings for industrial vacuum cleaners brass, reinforced plastic, stainless steel or aluminium.

To prevent damage to the hull when equipment collides with obstacles, a bumper can be located around the perimeter.

For this reason, the wheels and handle must be reliable. In addition, the length of the hose and power cable is of no small importance.

What additional options should I pay attention to?

Some models of equipment have additional functions aimed at increasing the comfort of their operation.

Motor overload protection

This the option is especially important for units that are actively used in large-scale production.

When the engine is overloaded, the equipment automatically turns off to cool down.

Light indication

Notifies the user when the dust bin is full, or the resulting blockage.

Adapters

Designed for fixing the device hose on the dust extraction system of power tools.

Automatic filter cleaning function

In the process of using the technique, the filters inevitably become clogged.

To save users from having to disassemble the vacuum cleaner and clean the filter, an automatic cleaning option is built into some models.

Filters are blown by air flow in automatic or manual mode.

The cost of devices with this option is slightly higher, but if the unit is planned to be used regularly, it's worth it.

Power outlet

Used to connect electric tools to the body of the unit.

In this case, the vacuum cleaner will turn on only after the tool starts working.

When the tool is turned off, the vacuum cleaner itself will stop drawing dust in a few seconds.

Suction force regulator

This option is not present in every model, but in some cases its presence makes the cleaning process more convenient.

Suction force regulator allows you to change the draft depending on the type of debris and the intensity of dust formation.

Features of caring for the vacuum cleaner filter during operation

Fine air filters periodically become clogged with dust or debris.

Owners of standard models technology you need to independently remove the filter element, clean it with the device included in the kit, rinse with water and dry thoroughly.

More modern models start cleaning the filter with a powerful air stream at the touch of a button.

Premium-class equipment performs this action independently, at a specified frequency.

Price categories

1. Budget - from 3 to 6 thousand rubles.
   Lightweight and compact devices suitable for home use.
   They will help to bring the apartment or garage in order after repair.
2. Medium - from 6 to 15 thousand rubles.
   More powerful units capable of removing construction waste in production conditions.
   They have a set of basic functions that allow you to efficiently clean your workspace.
3. Expensive - from 15 to 130 thousand rubles.
   Modern models with automatic filter cleaning, power outlet and other useful features.

   The main thing is to choose a model that suits your needs.
2. When choosing technology it is necessary to pay attention to the collection of what class of waste it is intended.
