Choosing the correct air compressor for you and your application is very important to California Air Tools.
Before choosing an air compressor, determine what air tools you are planning on using. This is very Important! We want to ensure that the air compressor you choose be will produce enough air (CFM) to operate your air tools or application properly.
Every air tool has an air consumption requirement.
This is stated, for example as: 2.20 CFM @ 90 PSI for the air tool to work properly.
A. CFM - (cubic feet per minute) is what air volume runs your tool. Some tools express as l/min (liters per minute); convert from l/min to cfm using a Google search. I.E. 100 l/min = 3.5 cfm.
B. PSI - (pounds per square inch) is the pressure of the flow of air. Often this is expressed in bar; convert from bar to PSI using a simple Google search. I.E. 7 bar = 101 PSI
This will help you determine the air delivery (CFM) you need from your air compressor.
For example the California Air Tools 8010 air compressor will produce 2.20 CFM @ 90 PSI.
If you plan on using an air tool or machine on a continuous basis, it is a good idea to multiply the “CFM” x 2 to get a continuous CFM rating for the tool or machine.
For example, if your equipment requires 3.8 cfm @90 PSI (or 108 liters per minute) and you plan on running for more than 1 hour per day continuously, then you will need to obtain a compressor with a minimum specification of 7.4 cfm (this would be a 4 Hp model). If you plan to run more than 6 hours per day continuously, then multiply by 3, for a minimum compressor specification of 11.4 cfm @90 PSI (this would be a 6 Hp model).

Most all air tools and machines are rated for intermediate usage (not continuous), with the exception of milling machines, etc. Always consult the air tool or machine manufacturer for the correct CFM requirement.
