In almost every production environment, air demand fluctuates depending on different factors such as the time of the day, week or even month. Extensive measurements and studies of compressed air demand profiles show that many compressors have substantial variations in air demand.
Atlas Copco’s GA Variable Speed Drive+ (VSD+) technology closely matches the air demand by automatically adjusting the motor speed. Combined with the innovative design of the iPM (Permanent Magnet) motor, this results in average energy savings of 50% and an average reduction of 37% in the lifecycle cost of a compressor.
Why Atlas Copco Variable Speed Drive+ technology?
- On average 50% energy savings with an extensive flow range (20-100%).
- Integrated Elektronikon® Touch controller controls the motor speed and high-efficiency frequency inverter.
- No wasted idling times or blow-off losses during operation.
- The compressor can start/stop under full system pressure without the need to unload.
- Eliminates peak current penalty during start-up. • Minimizes system leakage due to lower system pressure.
- EMC compliance to directives (2004/108/EG

Excellence in integrated air quality
Untreated compressed air contains moisture and aerosols which increase the risk of corrosion and compressed air system leaks. This can result in a damaged air system and contaminated end products. Maintenance costs can far exceed air treatment costs. The GA 7-37 VSD+ provides clean, dry air that improves your system’s reliability avoids costly downtime and production delays, and safeguards the quality of your products.
