FAQs

What size air compressor do I need for air tools?

• The amount of PSI needed for air tools depends on whether the air compressor is portable or stationary as well as the size of the air tool. On average, air tools used with portable air compressors typically require 0 to 5 cubic feet per minute (CFM) at 70 to 90 PSI, and tools connected to stationary air compressor systems typically exceed 10 CFM at 100 to 120 PSI.

How often does the oil need to be changed?

• It depends on the type of air compressor you have. For rotary air compressors, you should change the oil every 7,000-8,000 hours. The reciprocating air compressor requires oil changes every three months.
