Atlas Copco's GA VSD+ oil-injected rotary screw compressors can reduce energy consumption by 50%
Atlas Copco's GA VSD+ oil-injected rotary screw compressors are built to reduce energy consumption. The 7-15 kW (10-20 hp) GA VSD+ range, including a full feature version with an integrated dryer, is also 15 percent more efficient than the previous generation and offers a 12 percent improvement in free air delivery.
Its motor exceeds the latest NEMA Premium efficiency requirements. Built upwards, the motor and drive train share a single drive shaft and are vertically aligned. In addition, the motor drive train is completely 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.
