Why use a variable speed air compressor?

It’s simple—want to reduce energy? Select the most energy efficient compressor money can buy!

Atlas Copco’s GA VSD+ range brings a game-changing innovation to the industry.

The GA 7-15 VSD+ variable speed drive compressor reduces your energy consumption by a staggering 50% on average, compared to idling compressors. 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 heart of the GA VSD+ is an interior permanent magnet motor, directly coupled to Atlas Copco’s best-in-class screw element: all of which have been in-house designed and have patents pending. All these benefits make the GA VSD+ the compressor of the future, setting a new standard in the industry for years to come.

GA VSD+ Features:

  • Free air delivery up 12%
  • Energy savings of 50% on average
  • Running as silent as 62 dB(A)
  • Canopy size 55% smaller
  • Tested & proven reliability

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.

Combined with the innovative design of the iPM (Permanent Magnet) 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.

A new, more efficient fan motor achieves another saving on specific energy requirements of up to 7% of the compressor power. On top of the energy savings, the GA VSD+ realizes a Free Air Delivery (FAD) increase of up to 12%.

The design of the motor and the drive train are protected by pending patents.
