How to Size and Select an Air Compressor

Your air compressor is a source of power. Whether you are a weekend enthusiast or a business owner, you have the right size air compressor to power your air tools properly and effectively. Choosing the best air compressor to meet your needs is simple, if you follow these steps.


Pneumatic tools require a compressed air volume (expressed as cubic feet per minute, or cfm) at a specific pressure (expressed as lb-force on measuring square inch, or psig). The performance of the compressor is determined by the rating cfm and psig, not necessarily its horsepower. So you can skip the reviews horsepower when sizing and selecting a compressor.

Gather all your pneumatic tools together. Write down cfm needed to operate each tool, as prescribed by the manufacturer. If you can not find this information, you can look online for a chart of standard requirements for conventional pneumatic tool.

Add together the requirements of all cfm of compressed air tools you plan to run simultaneously. This figure rose to 25% to allow for the additional tools, future growth, and gas leaks last system.

Determine the maximum pressure (psig) needed to run air tools. You do not need to add value psig together as you requested cfm; simply use the value of the tools you need the greatest amount of pressure.

Make sure that the characteristics of the compressor motor compatibility: As a source of single-phase or three-phase power your? What is the voltage? Commercial housing and there is usually a challenge, 115 volt, 60 cycle power, while industrial buildings usually have a three-phase power source.

Small compressor should be used with an air receiver, or tanks. The receiver stores the compressed air and reduce run time of the compressor load. Recipients air should be at least 5 gallons per cfm for optimal results.

Make your cfm, max pressure, motor characteristics, and size requirements on center agent receives the compressor or improve your local housing and feature comparison between brands. Keeping these factors in mind the quality; you will definitely get what you pay for air compressors.
