Which building to choose a vacuum cleaner

Building cleaner - a necessary piece of equipment at a construction site, during repair work, at work or in a small workshop. Machine to effectively cope with the cleaning, you need to know how to choose an industrial vacuum cleaner and define selection criteria.

Selection of construction waste bin depends on operating conditions. Working properties allow scavenge devices of varying complexity and danger to humans. According to this indicator devices are divided into three classes:

class	The complexity of the dust	Structure
L	usual construction	Shavings, chips rubble, bricks, paint, varnish, gypsum, clay
M	Central danger	Copper, manganese, nickel, tin, dust with increased radiation background
H	high-risk	Allows completely dispose of asbestos residues, preservatives, dyes, fungus, mold, and other dangerous microorganisms

Criterias of choice

To select specific model you need to understand the main technical parameters. They determine the quality of the construction of the vacuum cleaner. These include:

power;
design and material of the housing;
Kit and the appointment of the filters;
food;
additional functions.

Power and other parameters

For functional industrial vacuum cleaner is required a high power level. He should significantly greater than the number of domestic counterparts. So the unit can easily cope with the garbage of any complexity require power from 1500 watts.

Devices with different parameters such high levels of such characteristics:

degree of air dilution;
turbo rotation speed;
air flow.

Buying a vacuum cleaner with a powerful engine, will have to come to terms with its large size and weight.

To the apparatus was mobile, it is necessary to consider the number and design of wheels for travel, the power cable length hose size. Carrying handle in his hand must be high quality.

On the machine size increase will affect the availability of the cleaning function. Since it is required in the design of integrated moisture protection of electrical elements.

housing

Sophisticated application conditions at high risk of accidental damage to make products manufactured from a metal housing. It can be steel alloys, brass, copper, aluminum, other metals, and combinations thereof in various proportions.

Smaller models can be made of durable plastic. User comments recommend combined model where metal is used for the reservoir, while the remaining elements are made of plastic. So saving unit weight and price decreases.

To mitigate the impacts provided a shock absorbing bumpers. Large models are mounted on a mobile frame with rubberized wheels, less weight - in the "grand piano pairs."

volume of waste bin

For cleaning large heavily soiled areas require the device with a large container. Typically, these are large units with reservoir from 40 to 60 liters.

When fully loaded weight of the waste bin is further increased. Therefore, they are often mounted on a frame with rubberized wheels.

For small rooms with light pollution enough capacity from 15 to 20 liters.

Food

Depending on the application and size in such a vacuum cleaner can be different drives power plants. There are three basic types of power supply:

From the built-in battery with the battery.
From a standard household network.
From the three-phase network.

The first and second options are used in small-sized devices for homes or small workshops. Last is more suitable for large-scale industrial facilities.

filtration methods

Filtering must fully ensure a high level of dust disposal. By type of construction of the building element dust collector is not very different from the household. It can be used, such filters:

paper;
cloth;
cyclone;
Multistage with akvafiltratsiey.

paper

Good keep dust from small particles with allergic properties. Not require regular cleaning and emitted as the filling. Among the shortcomings reviews usually point:

low tensile strength;
not suitable for chips, glass and other debris with sharp edges;
the high price of the replacement.

cloth

Reusable, do not require constant replacement and cheaper. Designed for large debris and dust residues, but ill keep small particles. They have a high probability of clogging, require regular cleaning. Such filters provide partial filtering.

cyclone

Cleaning using eddy currents. Good keep dust, suitable for operation with coarse particles, are suitable for collecting liquids. Among other models of such devices are the most positive reviews.

aquafiltering

This multi-purpose system. The foamed water stream of air keeps the larger elements of the separator where the fine particles are deposited. Provide complete cleaning, but require large amounts of water.

Additional functions

These options allow you to:

connect the working tool and synchronize its work with a vacuum cleaner;
regulate cravings;
automated filter cleaning;
control the operating parameters;
protect electrical installations from overload.

These features are optional, but extend the capabilities of the device and make it more convenient to use.

Synchronization with the tool

For this, the cleaner body to be set socket. After connecting the instrument at the same time it will run a vacuum cleaner. This is useful when you need to remove dust and chips at once at the time of grinding, drilling or other work. For synchronization must match the power plug and the tool cleaner.

Changing traction

Function is not mandatory, but it is necessary when dealing with pollution of varying complexity. It allows you to adapt the capacity to the current task - to increase traction in heavy large debris and reduce when working with light. It may be performed by an electronic or mechanical regulator special valve.

Auto Cleaning filter

It accelerates and facilitates maintenance. Valve mounted above the filter, makes it possible to change the direction of air flow and purge the underlying filter. The auto mode is activated when reducing thrust can be connected manually.

Control of operating parameters

Implemented by a light indicator. Sensors monitor the operation of the device and indicate when the filter clean, hose, filling the waste bin.

congestion avoidance

The system is relevant for high-power devices. It can automatically turn off the vacuum cleaner in case of overheating, apply a double to start the engine with a gradual set of power.

manufacturer's reputation

Building vacuum cleaners are expensive. So often there is a desire to save money and choose the low-end phone from a little-known brand. But such savings would lead to problems in the operation and the high cost of frequent repairs. Better to choose a vacuum cleaner known brand with an established reputation. Among them are:

German «Bosch», «Metabo»;
Japanese «Hitachi», «Makita»;
American «DeWalt»;
domestic "Interskol", "Union" and others.

If the budget is limited, pick a device on the user feedback.

The best models

To facilitate the selection of vacuum cleaners from different manufacturers taking into account the users were collected.

Bosch GAS 20 L SFC

This vacuum cleaner copes well with dry and wet cleaning. Excellent draws a lot of dust. The tank holds 15 liters, and the dust bag - 6,7 liters. Operates at a power of 1200 W and provides cleaning class L.

Among the options in this model there is a semi-automatic cleaning of the filter, remote switch, a set of nozzles, comfortable wheels to move.

Pros:

quality assembly;
powerful force garbage suction;
robust housing;
the possibility of connecting the instrument.

Minuses:

on the body much dust settles;
there is a wide nozzle for quick cleaning of small debris.

makita VC2512L

If necessary, the unit can be used without a bag, as integrated within a detergent filter. The degree of filling of the bag does not reduce the traction force.

Benefits:

light;
it is possible to connect instruments;
long cable and hose;
It collects all of the fine dust.

Disadvantages:

if among the debris comes a large stone, he gets stuck in the hose;
there is no seal between the dust bag and the motor.

CAP-7320 Union
