Before you start choosing a construction vacuum cleaner, you need to clearly define for what purpose you need it. When you know the capabilities of the equipment and its main characteristics, you can choose the best option for yourself.
The main feature of any construction site, large industrial premises and workshops - in general, any place where a hammer drill, jigsaw and wall chaser is used, is a large amount of sawdust, dust and other debris. The lesser evil for workers in such places is the inconvenience.
Dust, which is finely dispersed during such work, gets into the lungs, and can cause irreparable harm to health.
In addition, it often becomes the main reason for the failure of various electrical tools.
The only and correct solution in this situation, which will help protect workers from health problems and extend the life of the devices, is to buy a construction vacuum cleaner. He will be a faithful assistant for creating comfortable working conditions, creating safe working conditions and reducing the time spent on cleaning the production premises.
Since this article was written in the first place for those who have not yet used such a device, we will start with the main one.
Everyone who is thinking about buying their first construction vacuum cleaner asks the question: "What is it and why you can't use a household ? ".
Yes, at first glance, these two devices do not differ in any way (well, perhaps in dimensions). But with a similar principle of operation and device, they are designed for completely different tasks, which leaves a certain imprint on the design features.
The main difference between such similar vacuum cleaners is what they "fight" with. Household vacuum cleaners do a great job with house dust, but if small stones get into them, they are unlikely to end up in the dust container. Even worse, if you try to collect fine construction dust with a simple vacuum cleaner: the device will "spit out" most of it with an air stream through the air filter.
In addition, some of the dust will get into the electric motor, which, most likely, will cause the device to fail.
A similar model for industrial waste is designed for larger waste and other construction waste. By the way, the scope of work in production will only be within his power.
A distinctive feature of a construction vacuum cleaner is a shock-resistant body, a larger hose diameter (compared to a household analogue), an increased dust collector volume (which increases the size and weight of the device), a multi-stage filtration system, high engine power and the ability to work for a long time. period of time without interruption.
The principle of operation of any vacuum cleaner is quite simple and familiar to everyone who has passed the school physics course. The electric motor drives the fan, creates a vacuum inside the vacuum cleaner body, which is the main driving force. Air, in which dust and solid inclusions have already appeared, rushes through the hose to the zone of reduced pressure. 70% of the trapped debris remains in the dust collector, and the rest is "caught" by filters. The air that passes through the multi-stage filtration system comes out through a special opening into the environment.
The main difference between such a vacuum cleaner is that you can collect garbage both during operation and upon completion:
Thus, the amount of dust that will be released into the air will be minimized. Of course, the connected hose will make the work process a little more difficult, but for comfort and health you can put up with such a small inconvenience.
When choosing a construction vacuum cleaner for repair, you should pay attention to the fact that according to the type of dust collector they are divided into bagless and bagless.
The second type can be used at the request of the user and is reusable (i.e. fabric), and disposable (paper). Bagless vacuum cleaners are also divided into subspecies, since there are cyclonic (with a container) and aqua vacuum cleaners. We will consider the features of all types, as well as their advantages, disadvantages and characteristics.
| Cloth bags |
| Paper bags
| This type of filter is the most common and familiar to many, since it is very common in household vacuum cleaners. After such a bag is full, it is emptied and put back in place. You can use such a filter many times, which means that buying a vacuum cleaner with a cloth bag is generally considered a low-budget purchase. To create such bags, satin is used, which is a cheap and durable material. True, for the last few years, other synthetic fabrics (most often non-woven) have been used. |
The main advantage is the low cost per filling cycle. But there are also disadvantages.The fabric, which retains coarse debris so well, allows fine dust to pass through, which will fly over a long distance at the exit. But note that if the bag is made of two-layer non-woven fabric, you have nothing to fear.
| Such filters are literally disposable, and after purchasing a construction vacuum cleaner they will be a permanent consumable - they cannot be used again when filled, so you just have to throw the filled bag into a landfill. |
On the one hand, it is convenient, but on the other, it is additional costs, and considerable, since the cost of one bag ranges from $ 5 to $ 7, and at some point you will realize that you have spent more money on consumables, than the vacuum cleaner itself. In addition, such filters will run out at the most inopportune moment, so it will not always be possible to finish the work on time to the end.
But there is a bucket of honey for such a fly in the ointment. Paper bags have excellent performance characteristics. They are superior to fabric bags in terms of trapping small particles, which means the room will be very clean and you will need to clean and change filters less often.
But you should be careful with large construction waste: sometimes particles (glass, shavings, pebbles) can break the walls of the bags, and then all efforts will be in vain.
| Construction vacuum cleaners for repairs with a cyclonic type of filtration, debris is collected in a special tank under the action of centrifugal force. The disadvantages of such a device are an increased noise level, which is a direct consequence of the collision of large particles that enter the tank, as well as a limitation in application. The last minus is expressed in the fact that such vacuum cleaners are perfect only for collecting large / wet debris and water. Most of the "cyclic" models can also work with bags. |
In this case, the main filter will become much less dirty.
| Vacuum cleaners with an aquafilter pass the air drawn in through the water, so that large debris settles. Smaller particles are perfectly captured in the second water tank - the separator. This multi-level filtration system gives excellent results. But such an ideal device also has a disadvantage - namely, the high cost.
But if you are still going to buy a water vacuum cleaner, then the only consumable when working with it will be water, which should be changed periodically. A small snag - if you use the device in a place where repairs are being carried out, there may be difficulties with the presence of water.
In addition to the dust collector, the filtration system includes one (and sometimes several) filters for fine air purification. They are also reusable and disposable, and are made from nylon (for small particles), polyurethane (for liquid / moisture) and other synthetic materials. The main function is to collect fine dust that the main dust collector missed.
The final cleaning quality and engine wear depend on them.They, like the main filter, also need to be cleaned, because a dusty filter is the main reason for a decrease in device performance and engine overload. If you want to save money on the vacuum cleaner and the quality of the main filter, prepare yourself to change and clean the filters much more often.
Vacuum cleaners that relate to the term "construction" and "industrial "are not synonymous. All vacuum cleaners created for industrial purposes are divided into professional and household (do not confuse with those that you use to clean carpets at home).
They differ among themselves in the volume of the dust collector, the suction force, the productivity (the volume of the intake air in a certain unit of time) and the time of non-stop operation. To choose a construction vacuum cleaner for your working conditions, you should evaluate the required intensity of use of equipment. If you are talking about several hours of work a couple of times a week in a home workshop or apartment being renovated, a household vacuum cleaner is for you. If you plan to use it on a large scale and the device will have to work for an entire shift, you need a professional model.
The classification is based on the type of contamination to be removed.
Let's highlight the following varieties:
Such models cope not only with dry waste, but also with liquids.
These models come with a certain motor configuration without carbon brushes, which can cause sparks. Even in such devices there is always a function of changing the air flow rate. Such devices are the most expensive, but only required for narrowly focused enterprises.
Based on the name, it is easy to understand that they are used to collect hot waste (for example, heated metal shavings).
How to choose a construction vacuum cleaner according to these two parameters? You should know that they are interconnected: the more engine power, the higher the performance, and therefore the resource.As a rule, the power consumption of such vacuum cleaners is 1-1.5 kW, which allows setting the throughput of up to 55 liters of air / second. In professional models, the energy consumption is up to 7 kW, which increases the productivity up to 100 liters / second.
There are vacuum cleaners with two motors connected in parallel: according to the situation, you can turn on one first (and save electrical energy), or both at once (which will increase productivity).
The vacuum generated by the fan in the vacuum cleaner determines the suction power. This value in construction vacuum cleaners can be from 17 to 250 millibars. The higher the value, the heavier the particles can be absorbed by the vacuum cleaner. Also, the degree of vacuum shows the work efficiency even better than the power consumption.
Typically, the filter volume ranges from 25 to 50 liters. If you do not need to clean up a lot of debris, do not chase after large models, as this significantly affects the overall dimensions. But for professional models, the volume of the dust collector reaches up to 100 liters, which allows you not to take breaks during the work shift.
Some models have additional functions that are not essential, but make your work easier.
This socket on the body is installed for connecting tools. When connected, the vacuum cleaner will work only when the device is running. A very useful thing, but you should carefully consider the choice and compare the maximum power of the outlet and the tools planned for connecting.
So, depending on the type of waste, you can change the intensity of the suction.
The system sometimes triggers itself when the work is difficult, but you can turn it on manually. These vacuum cleaners are an order of magnitude more expensive, but worth it.
This device is versatile for different types of cleaning, and is suitable for periodic and regular use. The manufacturer has provided for the connection of an electric tool, the power of which will not exceed 2.6 kW.
A rather miniature device for dry and wet cleaning. The dimensions of this "Chinese" make it possible to use the vacuum cleaner in a confined space (small workshop, car salon). The model is perfect for those who will rarely use the device and store it in the apartment.
This full-size German has a low power consumption of only 1.1 kW.
The Hummer is a professional dust and water vacuum cleaner with three motors, the total power of which is 3 kW.
Now you know which construction vacuum cleaner you should choose. With the information described above, it will be easier for you to navigate the wide range and make the right choice.
