Rotary screw compressors reduce energy costs

Kaeser SM series rotary screw compressors combine SIGMA 06 air ends with IE4 motors. They include a dual-flow fan; an external-facing cooler; and a dual-flow fan with die-cast, sickle-shaped blade. A built-in web server and communications ports allow remote monitoring. The compressors are available in 7.5 to 15 HP, with flows from 19 to 55 cfm and pressures up to 217 psig.
