In the arsenal of professional construction teams quite often there are pneumatic or electric compressors. These devices are designed to form a compressed air mass, there are situations in which they simply can not do. In the modern market of compressors, there is a huge variety of them. Let’s look at the features of varieties of equipment, and find out how to properly choose compressor.
Getting to the Choice
It’s good to immediately understand that there is no compressor for all occasions. This is due to the fact that the equipment is used for various purposes, therefore the devices themselves can vary greatly. Most often, for general construction works, equipment capable of delivering pressure up to 8 atmospheres is enough.
Beginners at choosing compressors pay most attention to the volume of the receiver: it seems to them that this is the most important indicator. This capacity may have a volume of 24 to 50 liters. However, other properties of the device are important, and in some cases even more significant.

Often motors with the same blocks find their application in models that have different sizes of receivers. In such situations, models with a large receiver can lead to a considerable increase in their cost, but their marginal benefit is minimized. It is advisable to use products equipped with large receivers when you need compressed air more than once, several times a day. The device will be able to create conditions thanks to which it will not be necessary to turn on the motor every time when you need a small amount of air under pressure. If the compressor is intended for painting the house, then a small receiver is enough for you.
Other important features
When choosing compressor equipment, it is important to consider its manufacturer. If you want to minimize overpayment, while having the necessary compressed air, then you need to make an approximate calculation of the air flow by all used pneumatic tools that will operate at the same time when this compressor is operating. This goal is easily achievable: each instrument has passport characteristics, which indicate their air mass consumption.
This technique allows you to choose the best compressor manufacturer. But in this case, it is important to take into account the following factor: in models of foreign production, productivity is indicated at the input, therefore this indicator is 30% higher than the output characteristics. This leads to the fact that in domestic production technology the power reserve is about 10-20%, and in foreign at least 35%.
Among other important characteristics, the utilization of equipment in one shift is highlighted. It allows you to determine how much time a particular device is able to work without turning off. Domestic standards define this indicator at 0.75, which indicates a short-term operation of 0.15 and long-term – 0.5. Thanks to this characteristic, you can find out about the features of the equipment, however, it does not give an idea about the cessation of the flow of air leaving the receiver until the last one is empty.
Reciprocating devices provide fragmented consumption. If there is a need to organize a continuous cycle, then the best option would be to use a screw compressor. But in this case it must be taken into account that such equipment should not be used in the mode with constant interruption, since in such designs the compressor unit has a constant temperature.
Electric models can have one phase or be three-phase. If you often do field work, then pay attention to the study of systems that operate from the internal combustion engine or generated electricity.
If desired, you can purchase mobile kits, which include a compressor, inverter and electric current generator. This set is enough for you to provide the average construction site with the required amount of compressed air.
The purpose of the equipment allows you to classify it into domestic, professional and industrial use devices. Each of these devices is distinguished by its characteristics of productivity, pressure and engine life. For a workshop of small sizes, garages and cottages, you need a model that allows you to get 350 liters per minute in output. If you plan to perform lengthy work, then it is worth taking a closer look at professional equipment. They are highly reliable, however, the prices of such tools are higher. Acquiring them for domestic use is simply impractical: their motor resources simply will not be worked out.
In the article, we examined the characteristics of various equipment, which will help choose compressor. Try to get acquainted with the characteristics of the product well, only in this case you will be able to select the best option that meets your wishes and wallet.
