Rotary screw air compressor
The CSG-2 SFC, DSG-2 SFC, and FSG-2 SFC variable speed, oil-free air compressors are available from 75 to 450 hp and cover flows from 125 to 1788 cfm at 125 psig and are designed to deliver part load efficiency and steady pressure for applications. The core of these SFC model’s top performance is their premium, two-stage compressor airend. The rotors’ coating can handle temperatures up to 575°F. Stainless steel rotors in the second compression stage help guarantee compressed air quality and significantly increase service life. Units come standard with Sigma Control 2. Additional features include IE3 premium efficiency motors with PT 100 sensors to measure and monitor winding temperatures for maximized motor switching frequency and minimized idling. The hydraulic inlet valve eliminates replacing pneumatic diaphragms, resulting in reduced service costs and downtime.
