Air compressors come in different sizes, and variations. There are different horsepower motors, different size tanks, different piston configurations, but perhaps more importantly, all of them are rated in cubic feet per minute, or CFM of compressed air.
Typically a compressor is rated at a certain number of CFM at a specified pressure. The portable 30 gallon Eastwood Compressor that is our best seller (#31436) is rated at 5.7 CFM at 90 PSI (pounds per square inch), while its 80 gallon bigger brother (#31440) is rated at 22.1 CFM at 100 PSI. Meanwhile our Straight Line Sander (#13747) is rated at 5 CFM at 90 PSI, while our 50-lb. Pressure Abrasive Blaster (#51117) needs 10 CFM at 90 PSI, and the popular Devilbiss Finishline HVLP spray gun (#12826) needs 13 CFM at 23 PSI. So that gives you some frame of reference.
All Air Tools require a certain amount of CFM to operate properly. Below is a reference chart for the Eastwood Air Compressors and what Eastwood Pneumatic Tools are compatible with them. This chart can also be used as a reference for other Air Compressors and Air Tools, but you would always need to check the manufacturer for their specifications.
Air Tool to Compressor Chart
*All Eastwood Air Compressors have a 70% duty cycle.
*All above figures were calculated within the duty cycle of the compressor.
*All tools above will work with any Eastwood Air Compressor model but if extended use is expected, we recommend purchasing a higher CFM
model for uninterrupted use.
