Construction vacuum cleaner: how to make the right choice

On construction, production and other work sites, work is often carried out using perforators, various jigsaws and other similar tools. As a result, a lot of dust and various garbage appears. The greatest danger to human health is fine dust.

And a construction vacuum cleaner (SP) is an excellent assistant in the elimination of this garbage and a defender of the health of people working in these rooms. Which is better to choose a construction vacuum cleaner, we will analyze the points below.

Differences of the joint venture from the household version of the vacuum cleaner

At first glance, this is an overall difference. However, the main difference between these devices is their work front. For example, a vacuum cleaner for a shtroborez is irreplaceable at European-quality repair.

The household model easily eliminates light house dust. But with small pebbles she already has difficulties. Fighting very fine building dust causes even more problems. A significant part of such dust is spilled out by the household appliance along with air. A lot of this dust is in his engine. As a result, the device soon breaks down.

A vacuum cleaner for construction and repair is already designed to combat building dust and other waste from the construction industry. In addition, he copes with more serious volumes of work than a household appliance.

Specifics

1. The housing is shock resistant.
2. The hose has a developed diameter.
3. What is the difference between a dust bag? Of course, an impressive volume. Therefore, the joint venture itself has serious parameters.
4. Filtration technology has many steps. It is highly efficient.
5. And most importantly, the difference between the construction and the usual one is that it is a very powerful engine. It can work for a very long time without pauses and overheating.

Basics of work and device

The basics of the joint venture are the same as for the household model. The engine activates the fan, which forms a powerful vacuum inside the device. This is the main driving force. Air, capturing dust and other solid formations, moves to a place of reduced pressure.

The lion's share of trash trapped inside vacuum cleaner, remains in the dust bag. Particles retained in the air are captured by filters. Air, having passed the complicated filtration technology, leaves the environment already purified. Its exit is through a special hole. How to choose the right device for yourself or the team, we will analyze the technical parameters.

The following is a diagram of a joint venture device for concrete dust. For example, the model is BOSCH GAS 35 L SFC

Dust collectors

In a joint venture, as in a household model, a dust collector may or may not include a room dust bag. The first type is usually equipped with fabric or paper bags. Reusable fabric products, paper products - single use.

Bagless construction vacuum cleaner is divided into two categories:

1. Container Devices.
2. Water vacuum cleaners.

Features of fabric bags

Usually they are made from satin. Although lately, synthetic fabrics, especially non-woven, are becoming more common.

Pros of these bags:

1. A huge number of application cycles. This results in economic benefits.
2. Good toughness.
3. Large particles are well retained.

Minus:

Skip fine building dust. As a result, it scatters in the air.

Features of paper bags

In fact, these are consumables. After cleaning, they are thrown out along with their contents.

Cons of these bags:

1. Additional expenses. One such bag for a joint venture costs about 5-6 dollars.
2. Such bags run out quickly.
3. They can’t cope with large debris (pebbles, glass fragments, etc.).

Their advantages:

1. Superior performance.
2. Microscopic particles are well captured.

Features of container dust collectors

In them, the collection of all garbage is obtained under the influence of centrifugal power.

Their cons:

1. Very noisy work. The reason is that solid particles constantly hit the walls of the tank.
2. Limited use. Only large particles, water, and also moistened garbage can be collected.

Today, in many container models, bags can be placed. So the main filter produces significantly less pollution.

Aquafilter specifics

The air they suck in passes through the water, where large debris is concentrated. And very small particles are trapped in separator. This department is located behind the water tank.

Their cons:

1. Decent cost.
2. Do not overpower significant amounts of garbage.
3. Consumable - pure water. For example, on the site where repairs are underway, it is difficult to get it in solid volumes.

Filters

They can be single and multiple use. Materials for their manufacture:

1. Nylon. Suitable for very fine dust.
2. Polyurethane. It sucks fluid well.
3. Synthetic options.

The main duty of filters is to capture finely dispersed formations that have left the main tank or bag.

The condition of the filters affects the level of cleaning of the working room and the degree of wear of the engine.

From filters periodically it is necessary to eliminate the accumulated pollution. If they are clogged, the entire performance of the device is reduced.

Kinds

Typically, the joint venture is distributed to household and professional modifications. They differ in parameters, potential, suction power, duration of work without pauses.

If you need to clean a small room and work takes several hours a week, an inexpensive household modification is suitable.

When you need cleaning in a huge production room and it requires a huge investment of time, a professional machine is required.

Differences of the joint venture by purpose

The purpose here is the type of pollution that the joint venture must eliminate.

According to this principle, the following models are distinguished:

1. For the implementation of dry cleaning. This is the simplest task. All joint ventures cope with it.
2. For combined cleaning: dry and wet. Such modifications cope with dry debris and spilled liquid.
3. For washing. The apparatus also performs dry cleaning and mopping floors in rooms with high traffic.
4. For the collection of waste that poses a risk of fire or explosion, for example, powders from aluminum and zinc, dust from coal, organic industrial waste.
   The engines in devices for such cleaning do not have graphite brushes. Also in these joint ventures there is an option to calculate the dynamics of the air flow.
5. For cleaning rooms from hot industrial waste. These are heat-resistant devices. Scope - metal processing workshops.

The nuances of choice

The cost of the joint venture is quite high. And based only on its price and brand name do not do it. In order for your purchase to bring you effective results, vacuum cleaners must be equipped with:

1. 1. Conditions for future work. It is worth deciding which model you need: professional, domestic or highly specialized. What rooms will be cleaned? Will they be dry or with water? Will dust collect or mop the floors?
      It is also important to look at the level of danger. It is usually indicated by manufacturers. L is low, it is a lot of construction pollution. A simple filter also handles them.

      M - average level. These are: nickel, manganese, wood, copper and concrete dust. We need filters that capture 99.9% of such waste.

      H is tall. These are various carcinogens (for example, asbestos), waste with a huge concentration of microorganisms, as well as chemical toxins. It needs a powerful and sophisticated filtering technology for building vacuums.

      ATEX - special. This is a cleaning of flammable and explosive elements. Applied devices with a minimum category of electrical safety IP 54.

   2. Power and performance. The higher the first parameter, the larger the second. The usual power of the joint venture: 1.0-1.4 kW. Thanks to what their parameter of an air consumption reaches 50 liters of air per second. The power of professional devices is up to 7 kW. Potential - 60 - 100 l / s.
   3. Vacuum level. The fan of the device creates a certain vacuum. It affects the suction power of the apparatus. In a joint venture, this parameter lies in the range of 17 - 250 mbar. The more developed the vacuum, the more massive elements the unit absorbs.
   4. Dust collector parameter. Usually its volume is as follows: 20 - 50 liters. If you need to clean small rooms and volumes of garbage, buying an aggregate with a massive dust bag is illogical.
      Professional versions can have a dust collector up to 100 liters.
   5. Body. Usually shockproof materials are used for its manufacture: aluminum, steel (stainless steel), brass or reinforced plastic. Also, a bumper can be mounted to the body. He does not allow accidental blows of the body against any obstacles.

Additions

They are not mandatory, but facilitate the operation of the apparatus. The more of them, the more expensive it is.

They can usually be equipped with the following add-ons:

1. Special outlet. It is located on the device. Its function is the direct connection of electrical tools. When buying a joint venture, it is important to consider the power of those tools that you will connect to it. It is better to give preference to an instrument with better power.
   
2. Suction power controller.
3. Automatic filter cleaning. This mechanism is located above the filter and has a special valve, due to which the vector of the air stream changes and the filter is blown, thereby eliminating pollution from it.
   
4. Adapters They allow you to attach:
   - joint venture hose to the dust extraction mechanism in tools,
   - special splitters - useful when you need at least two dust-generating devices at once.
   
5. Indicator light. It reflects the condition of the vacuum cleaner, reports a clogged compartment (hose, filter or dust collector).
6. Engine protection against overloads. This is a very useful option for industrial models used in harsh environments.

Service Principles

These principles come down to regular cleaning or replacing filters, as well as the dust bag.

If the joint venture has a paper bag, then it is simply replaced. Other types of dust collectors need to be freed from their “content” and cleaned well.

Filters

If you have a simple model of a joint venture, then you need to clean them yourself: a clogged filter is removed, cleaned, washed with running water and dried.

If you have a more powerful version, then the cleaning takes place on the machine. You just need to press a button, and a powerful air stream, moving along the reverse vector, will quickly save the filter of all dust.

If you work with a high-end device, then you don’t even have to worry about dirt in the filters. In such models, self-cleaning of these components occurs periodically.

Features of a vacuum cleaner for a chipper

A wall chaser with a vacuum cleaner is a narrowly targeted tool used in construction for cutting recesses in brickwork / concrete for electrical wiring or other communications. In appearance, it resembles a grinder, but the rotation speed of diamond discs is much greater, and safety during work is much higher.

For such tools, only a construction vacuum cleaner is suitable, an ordinary home version with a volume of heavy dust is not able to cope. Such products differ from the household counterpart:

1. Shockproof housing.
2. The hose is much longer.
3. The dust collector has a large volume.
4. More sophisticated air purification system.
5. High power and performance.
6. Long work without a break.

The peculiarity of construction vacuum cleaners is that they remove dust during the operation of the chaser - the hose is connected to a special nozzle on the tool. With this connection, dust dispersion is minimal, but there are some inconveniences: the connecting hose from the vacuum cleaner sometimes interferes with the smooth movement of the tool.
