Rotary screw compressor
The 7-15 kW GA VSD+ range of compact, oil-injected rotary screw compressors feature an integrated dryer and a motor that exceeds the latest NEMA Premium efficiency requirements. The motor and drive train share a single drive shaft and are vertically aligned. In addition, the motor drive train is enclosed, resulting in a NEMA 4 rating for protection against dust, debris and water. A single closed oil-circuit cools the motor and lubricates the element and bearings, resulting in an efficient, quiet compressor (down to 62 dBA). Additional features and improvements include a more efficient fan and a strong air intake system.
