Innovative
Atlas Copco has revolutionized compressor build and performance. Instead of the normal space taking horizontal design, the new GA 7-37 VSD+ has an upright, compact layout. This saves valuable floor and work space, eases maintenance access, and reduces the total cost of ownership for all customers.
Efficient
Reduced energy consumption by 50% on average compared to the current idling models.
Free Air Delivery (FAD) increase of up to 12%.
Meeting and exceeding efficiency benchmarks:
The iPM motor of the GA 7-37 VSD+ equals IE5 standards.
The inverter and iPM motor exceed IES2 (EN 50598) requirements for power drive efficiency.
Reliable
Low maintenance: fewer components, increased uptime.
Based on the unique combination of proven technologies and existing components, optimally brought together by Atlas Copco's experience and know-how.
Smart
Easy monitoring and maintenance thanks to the Elektronikon Touch controller.
Maintenance notifications and machine status are available via SMARTLINK e-mail or text messages.
Customized reports on the energy performance of your machine, in compliance with ISO 50001.

VSD+ for 50% average energy savings
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.
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 with directives (2004/108/EG)
Advanced monitoring, control & connectivity
Whether you call it industry 4.0 or the Internet of Things (IoT), interconnectivity is the future. The GA 7-37 VSD+ comes fully prepared. Its advanced monitoring, control, and connectivity features allow you to optimize compressor performance, resources, efficiency, and productivity.
CONNECT SMARTLINK: Data Monitoring Program
Remote monitoring helps you optimize your compressed air system and save energy and costs.
Provides a complete view into your compressed air network.
Anticipates potential problems by warning you upfront.
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.
On average 50% energy savings with newly designed integrated dryers
Pressure dewpoint of 3ºC/37.4ºF(100% relative humidity at 20ºC/68ºF).
