Rotary Screw compressors are available with a large range of flows from 4-250 HP and air flow rates from 10 to 1500 cfm and larger. Most screw compressors have pressure ranges from 100-150 psi. Rotary screw compressors require frequent maintenance ranging from oil changes, filter changes and condensate management.
Rotary Claw compressors are available with flow rates from 65-350 cfm and pressures ranging from 15-30 psi. Claw compressors require little to no maintenance. Standard gear oil changes are 20,000 hours. Inlet filters may require more frequent changes based on the air quality of the environment in which installed.
Rotary Vane compressors are available from very low to moderate air flows typically 3-325 cfm with pressures from 15-25 psi. Rotary Vane compressors require changing of filters and vanes on a regular basis.
