Today, oil compressors are widely used in household and industrial activities. With their help, most tasks are simplified. In particular, paint sprayers, jackhammers, and pneumatic drills operate on the basis of these devices. The main advantage of oil compressors is their durability. They can also withstand long-term continuous operation. In addition, they use more durable parts compared to oil-free ones. However, this model also has a significant drawback. Oil tends to get into the compressed air supplied by the compressor. This factor will not affect the operation of the impact wrench in any way, but can cause serious problems when using a spray gun because the oil mixes with the paint. It is not difficult to imagine the effect of such a connection. These are not all the nuances that need to be taken into account before purchasing an oil compressor. KP contacted for details to the founder of the club and YouTube channel “We paint correctly” Valentin Druzhinin and compiled a rating of the best oil compressors of 2022.

Maximum developed pressure
Automotive compressors differ in the maximum pressure they can develop. In tires of cars, crossovers and SUVs, the pressure is usually 2-3 atmospheres. In truck tires, pressure can reach 10 atmospheres. Most modern automobile compressors develop a pressure of 10 atmospheres and cover the needs of most car owners with a large margin.

Type of pressure gauge and its location
All automobile compressors are equipped with pressure gauges. The pressure gauge is designed to monitor the pressure in a car tire.
Pressure gauges installed on automobile compressors can be:
- analog
– have a pointer and a graduated scale, are cheaper than digital and less accurate. - Digital
– they have a display on which the tire pressure value is displayed in the form of numbers; they are more expensive and have greater accuracy.
The pressure gauge can be located on the compressor housing or on the air hose. Many tire pressure gauges overestimate tire pressure. To determine the exact pressure, the compressor must be turned off.
How to choose an oil compressor
According to our expert Valentin Druzhinin, when choosing an oil compressor, you must first of all proceed from your needs. It is necessary to determine the immediate purposes for which the device will be used. Also suggest where it may be used in the future. In addition, it is imperative to take into account the requirements of pneumatic tool manufacturers regarding the minimum permissible values for compressed air consumption parameters.
Piston or screw
In its operating principle, a piston compressor resembles a bicycle pump. Air enters and is compressed by the movement of the piston, and then exits the exhaust valve. The main feature of this device is its operating mode - intermittent. This means that this type of oil compressor needs to be stopped briefly during operation to cool down. However, this drawback can easily be “forgivable”, since it is compensated by many advantages, including low cost, simplicity of design, ease of maintenance and repair. As for the screw compressor, its operating principle resembles that of a meat grinder. Air compression in a screw compressor is carried out using two screws rotating together. Unlike a piston compressor, in which the compression phase periodically alternates with the intake phase, air compression in a screw compressor occurs continuously. It is considered more modern and advanced equipment. However, the cost of such a device is much higher.
Electrical wire length
The length of the electric wire and air hose should be sufficient to inflate any wheel. When choosing the length of the wire and hose, you should be guided by the length of the car and where you will connect the compressor: to the cigarette lighter or to the battery. There are compressors with a short wire and a long air hose, and there are compressors with a long wire and a short hose. It is best if the sum of the lengths of the electrical wire and the air hose is at least 5 meters.
Additional equipment – what to consider?
Buying just a compressor does not mean that the connection to the instrument will be configured correctly or the work will be done efficiently. The technical organization of the process often involves the use of special hoses, adapters and clamps. As practice shows, even light pneumatic tools when connected to a compressor require the use of clamps with suitable dimensions. Personal protective equipment should not be ignored either. If the compressor for pneumatic tools will provide spraying of abrasive materials, then it is necessary to take care of protective headphones, gloves and goggles. To work with paints and varnishes, it is also recommended to purchase overalls that will provide protection from chemically hazardous substances.
