Compressor for garage: features of choice

Compressors are equipment that is designed to compress air and then discharge it at high pressure. These devices are used for the operation of mechanical equipment and power tools, as well as control of production processes. Such units may be needed not only in everyday life, but also in garages, as well as production workshops, so they are so common today. And some types of equipment and can work at all only due to the air pumped under pressure, the quality of which is sometimes very important.

Classification

On sale today you can find a compressor for a garage in a wide range, it can be designed to solve household tasks or work in the industrial environment. This equipment is different internal device and technical characteristics. Before buying, you need to understand the models, as well as determine the goals. To date, you can find two types of air compressors - piston and screw.

Features of choice: screw compressor

If you need a compressor for the garage, then you can pay attention to the screw version of this equipment. As a rule, such devices are also used for assembly of tools and cars, they also found their application in the conditions of woodworking enterprises. The compressor for the garage operates according to a certain principle, which consists in the following: the air gets inside through the suction valve and then is pumped through the screw unit, cleaned in the separator and exits through the cooling radiator.

Why choose a screw compressor

As the main advantages of such equipment are the possibility of continuous continuous operation and noiselessness. These devices are very economical, they have high performance and consume less power compared to piston ones.

Features of reciprocating compressors

If you need a domestic compressor, then it is worth considering the option of purchasing a piston model. It compresses the air due to the piston, which makes reciprocating motion. This element is inside the case. In most cases, the piston type of compressors is used in everyday life in conjunction with spray guns, to ensure the operation of pneumatic tools, as well as to inflate automobile tires.

Classification of reciprocating compressors

The reciprocating compressor for a garage is divided into several varieties. So, the aggregates are:

• Oil;
• Coaxial;
• Oil free;
• Belt devices.

The first are used in conjunction with screwdrivers and pneumodrills. Do not recommend using them together with spray guns, which is explained by the danger of mixing paint and oil. Oil-free instruments allow you to get clean air at the outlet, which is devoid of impurities. Therefore, such devices have found wide application. But they have one drawback, which is expressed in a short service life.

Description of belt models

Belt devices have good performance, are distinguished by their durability and ease of maintenance. Reciprocating compressor household consumers are chosen for the reason that such a device is characterized by compact dimensions, low cost, which determines the household purpose. The main drawback is lack of ability to work continuously. Every 20 minutes such instruments should be allowed to rest.

Selecting a domestic compressor by performance

The choice of the compressor must be based on performance. This indicator is measured in liters per minute. Calculate this parameter is necessary, taking into account the needs of equipment that will be used together. It is important to study the technical characteristics of each model of the device, add up the indicators, which in the end will yield the required performance. But it should be borne in mind that the air compressor should not be loaded more than 70% of the figure mentioned by the manufacturer. That is why it is advisable to select a model with a capacity of 200 l / min more.

As an example of equipment with a capacity of 260 liters per minute, the PROFline RS 1800/50 compressor can be considered, the cost of which is 10,200 rubles. This piston equipment is a modern high-quality device for working in the country, in the workshop or in the garage. The model provides a stable supply of pneumatic tools. Reduce the number of operating cycles of the device can be a method of accumulating compressed air in the receiver. The body of the model is well protected against corrosion, because the outer surface is covered with a protective layer. Mobility is guaranteed by a handle on the body, which allows you to change the direction of motion when the compressor moves around the site.

Selection of equipment for operating pressure and power

The choice of the compressor must be carried out by the customer also on the basis of the working pressure. In this case, it is necessary to take into account the features of the tools used together. For example, a pressure of 4 bar is sufficient for spray guns. But for pneumatic equipment you need 6.5 bar. If you plan to use the compressor to operate the tire changer, you will need to increase the pressure to 10 bar. For industrial equipment, this parameter should be 16 bar.

Excellent for the garage is suitable model FUBAG AIR MASTER KIT, whose cost is 9800 rubles. The operating pressure for this equipment is 8 bar, and the power is 1.5 kW. For one minute the unit is capable of producing 222 liters of air. The minimum noise level is 85 dB. The compressor (220V) should be selected also with regard to the power that will affect the speed of operation. As mentioned above, this parameter should be selected with a margin.

An example of equipment with an average power can become the model "Caliber Master KB-1100M", the cost of which is 3700 rubles. The power of the unit is 1.1 kW, the output is 180 l / min, and the equipment weighs 6 kg. This oil-free instrument can be used to operate pneumatic tools. Apply a portable model can be in the field of construction and repair, as well as in the conditions of the garage. The equipment has a compartment for storage of a cord, a pistol and a hose. On the inner surface of the lid there are clamps for storing the nozzles. The length of the cable is quite impressive and is 1.4 m, but the length of the hose is 3 m.

Select by volume of the receiver

When consumers think about the question of which compressor to choose for the garage, they pay attention also to the volume of the receiver. It is worth noting that the devices described in the article provide a certain supply of compressed air, which makes it possible to guarantee the uninterrupted operation of the compressor, even when the compressed air level drops to a minimum. Such interruptions will be mitigated if the volume of the receiver is sufficiently impressive. However, it should be borne in mind that with increasing this parameter the compressor will have to fill the space for a longer time.

If you are thinking over the question of which compressor to choose for the garage, it should be taken into account that the air consumption of the instrument can be carried out evenly, in this case it is possible to do with a small receiver in volume. If the air comes in batches, it's best to choose a compressor with a rather impressive receiver.

As an example of equipment in which the volume of the receiver is 500 liters, you can consider a compressor (220V) brand ABAC GENESIS 2208-500, pay for which will have 676,000 rubles. This device is suitable for garages that professionally repair cars. Less expensive equipment - FUBAG SERVICE MASTER KIT, whose cost is 8900 rubles., Has a receiver with a volume of 6 liters. In this case, the working pressure is 8 bar, and the productivity is 180 l / min. This model does not have transportation wheels, but there are many other positive features, among them it should be noted:

• The presence of a handle;
• Safety at work;
• The possibility of visual control;
• Stability on the surface.
