How to choose a construction vacuum cleaner

Construction vacuum cleaners have the simplest operating principle. The electric motor operates thanks to the fan. It is this that creates the maximum vacuum inside, therefore it is considered the driving force. The incoming air, along with dust, moves through the hose of the device and ultimately enters a low-pressure zone.

The largest particles go straight into the dust collector, while the small ones are captured by auxiliary filters. And only after passing through this system, the purified air is released through the hole located at the outlet of the unit.

The main elements of the device are:

• fan and motor;
• a filter that purifies the air;
• container for collecting debris and dust.

In order to properly choose a vacuum cleaner, you need to understand the specifics and features of this device, which will be discussed later in the article.

Types of construction vacuum cleaners

Conventionally, they can be divided into two types: professional and semi-professional and household. They can also be distinguished by suction strength, parameter, potential and performance without pauses. Let's focus on the first classification.

• Household. Suitable for cleaning small spaces and short hours of operation (several times a week). This option is the most accessible, as it is purchased at a low price.

• Semi-professional differ from the first modification only in the greater power of the engine. In addition, they quickly adapt to construction waste. IMPORTANT! You should not carry out wet cleaning, because the bag may tear due to the entry of large material. This type of vacuum cleaner is also inexpensive. Another advantage may be the ability to carry out both home cleaning and cleaning in the car or garage.
• Professional. Suitable for cleaning large rooms, since they require a huge amount of time and a special apparatus. Designed for use on construction sites and in production. You can pay a fairly high amount of money for them, but the price is justified. Such units have a powerful motor with a bypass. The household waste bag is durable and can even be used for wet cleaning. The device is cooled by a separate air flow. Such vacuum cleaners can be subjected to various tests.

Criterias of choice

Of course, when choosing a construction vacuum cleaner, you should not focus on price. It would be more advisable to pay attention to the characteristics of the device. Only then will the upcoming work be carried out effectively.

Main criteria

• Power. The scale of work the unit will cope with will depend on its size. The highest figure is everything above two kW. Conventional vacuum cleaners are 1 - 1.5 kW (this provides the ability to release 50 liters of air per second). However, this criterion has a large impact on performance, and information about this is not always possible to find.

That is why you should focus not on it, but on the following points:

• Dust container volume. First you need to decide for what job you are purchasing a vacuum cleaner. As a rule, it ranges from 20 liters to 50. If you expect to clean with a small amount of debris, then you can take the optimal volume. However, if you take professional cleaning at a construction site, the value sometimes reaches up to one hundred liters;
• Since the weight and equipment are quite large, pay attention to way of moving. It shouldn't be difficult;
• Container capacity. This criterion can be viewed ambiguously. On the one hand, it affects the size of the device. Therefore, it will be inconvenient to work with large dimensions, but with significant capacity. On the other hand, the higher its indicator, the fewer times you will have to change the bag and clean it of debris;

• Dust collector type. There are two varieties: reusable cloth and paper with one-time use. The first of them needs to be changed a large number of times, and it also often allows small debris and dust to pass through it. Although they are much stronger than paper, they can still tear if they come into contact with large materials.

The second ones are disposable, which are much more convenient to use. Without much difficulty, you can get dirt, which, in principle, can be thrown out along with the dust collector. However, they also have their shortcomings and disadvantages. In addition to low strength, air resistance can increase, which usually results in a lack of power for the device to operate.

If construction requires a considerable number of cleanings, then financial difficulties may arise when using paper bags. The price for it is a decent amount;

• Terms of Use. Of course, you need to consider the point for what purposes you are going to use the vacuum cleaner. And your choice must be coordinated with pollution levels. There are several of them: L, M, H, Atex. They are written as the degree of contamination danger increases.

The first occurs due to construction waste. The second one is average. You need to use more than one filter for this. At maximum, it is necessary to use a special system that will provide filtration. And the latter needs an explosion-proof apparatus.

Additional functions

These are the functions that make it easier both for you to work with the device and for him to clean.

• Suction power controller;
• Automatic filter cleaning. The valve, with the help of which the direction of the air flow changes, thereby ensuring the filter is purged and clogging is eliminated. This additional element is located above the filter itself;
• To protect the engine from overload, special protection has been created. There is a special need for it in extreme and severe cases;
• When the dust collector is full or when the filter is clogged, the indicator can display such information;
• If you need to connect the device with splitters or with a hose, then adapters that allow you to do this will be useful.

Conclusion

To make a truly meaningful choice, you need to think carefully about the purpose of purchasing a construction vacuum cleaner. And on this basis, understand each characteristic of the unit. For example, to clean industrial premises you need a device with enormous power and a large dust collector. For cleaning garages or cars, a budget option is suitable, which will only be able to remove dust and small debris. However, you should always refer to the instructions, as some vacuum cleaners are afraid of water and certain types of debris.
