A new, more efficient fan motor saves up to 7% on compressor power for specific energy requirements. On top of the energy savings, the GA VSD realizes a Free Air Delivery (FAD) increase of up to 12%. Combined with the innovative design of the iPM motor (efficiency corresponding to IE4 efficiency), this results in average energy savings of 50% and an average cut of 37% in the lifecycle cost of a compressor.
Exceptional energy savings– Atlas Copco’s GA Variable Speed Drive (VSD ) technology closely follows the air demand by automatically adjusting the motor speed to match the compressed air supply to the air demand. The drive train is a completely closed, oil-cooled unit that is both quiet and reliable (IP 66), even in the harshest conditions. Highest reliability– The GA VSD has proven its reliability during extensive field-testing. All these benefits make the GA VSD the compressor of the future, setting a new standard in the industry for years to come. The heart of the GA VSD is an interior permanent magnet (iPM) motor, directly coupled with Atlas Copco’s best-in-class screw element, all of which have been in-house designed and have patents pending. At the same time, it offers improved performance, silent operation (down to 62 dB(A)) and a compact footprint, thanks to its vertical drive train design. 
The GA 7-37 VSD variable speed drive compressor reduces your energy consumption by a staggering 50% on average, compared to idling compressors.
Atlas Copco’s GA VSD range brings a game-changing innovation to the general industry.
