Compressor Terminology

Displacement volume

The amount of space the compressor can displace or pump in a single stroke. It is a measure of the compressor's capacity or ability to compress air and is the amount of space that the compressor can displace or pump in a single stroke. It is a measure of the compressor's capacity or ability to compress air or gas.

Free Air Delivery

"Free air delivery" refers to the amount of air that a compressor can deliver to the end-user without any additional cost. Displacement is the theory and CFM/FAD is the actual volume available.

Single Stage Compressors

Single-stage compressors describe a compressor pump with one or more cylinders producing the final pressure in compression/stroke.

Two Stage Compressors 

Compresses the air to its final pressure in two stages.

First stagethe air is compressed to a lower pressure ( typically 30psi) and then allowed to cool and compress a second time to its final pressure (normally 200psi). Two-stage compressors provide more air for less energy
