How to Choose an Air Compressor – A Brief Guide


Your company will, therefore, need the compressor. Therefore, you must find a job and submit it to the superiors on their proposals. The choice of the compressor – it’s responsible. Visit to read about Air compressor review. Before you walk around, you need to know in advance what type of machine suits your goals.

  1. What is the compressor?

The compressor is compressing gas.

  1. What type of gas should be compressed?

Answer is – “Air”, you need an air compressor. If you need to compress other gases – then look at a gas compressor or one of the specific compressors. The discharge of the separate compressors of carbon dioxide is used for liquid or solid carbon dioxide (carbon dioxide), and cooling compressor, compressed ammonia, freon or other refrigerant used in refrigerators.

  1. What is a performance, or how much gas should be compressed in each unit of time?

State or flow and measured in cfm or cfpm.

  1. What pressure should compress the gas?

(The first pressure, generally atmospheric, and if not, should we ask and what?)

The final pressure is commonly referred to as pressure release (outlet pressure, discharge pressure) and can be expressed as an absolute, either zero-based and most, ie, atmospheric pressure correction. Measure pressure on PSI.

  1. What causes the compressor to compress gas?

This is the journey. The trip is usually electric or diesel. Significant driving power, measured in kilowatt (kW) or HP horsepower, 1 HP = 0.74 kW and the speed measured in revolutions per minute (rpm). It is important for the voltage of the motor, measured in volts, (V), the frequency of the supply voltage, measured in Hertz, (Hz).

For useful estimates to note that for all 35.3 cubic feet per minute general purpose compressor (pressure 7 .. 10 atm.) Need a 7-8 kW installed drive location.

  1. Will the compressor slider affect?

When you answer this question, make a choice between the stationary and mobile compression station. Fixed compressors are installed in the magazine for a permanent, high-performance model – in the frame of the conveyor or foundation. Mobile compressor stations are mounted on the chassis and move to construction sites, road construction, petroleum industry … Click to learn more about it’s review.

  1. How cold is the compressor?

We all learned at school that the gas was heated during compression. Therefore, when the compressor is released by large amounts of heat, it is necessary to remove the cooling system. Main varieties – air-cooled and water-cooled. For the latter requires a recycled water supply, you should, therefore, request the water flow for each unit of time.

  1. What is inside the compressor?

Often, the cylinder with the piston (piston compressor, of course), or a pair of screws (screw compressors), which continues to be driven by the gas, reducing its volume. In general (with the same performance) to piston cost more noise, more and more easily repaired, and vis – che, quieter, safer and more economical.

  1. Has butter or with no butter?

To improve the efficiency of the compressor play between the piston and the cylinder with the piston compressor and between the screws – in a bolt – usually full of oil. Naturally, some oils are in the compressed air. For his department used oil separators and filters. In cases where the oil content in the compressed air should be very low or apply compressors without oil (dry) is more expensive than usual and less reliable or expensive set of high purity filters.
