7-37kw VSD Plus GA7-37VSD+ Atlas Screw Air Compressor

Oil-injected rotary screw compressors
GA 7-37 VSD+ (7-37 kW/10-50 hp)

A new standard in compressed air performance and efficiency
Atlas Copco’s GA 7-37 VSD+ is a true game changer for your operational environment. It reduces energy consumption by on average 50% and assures performance even in the harshest conditions. The GA 7-37 VSD+ comes with Variable Speed Drive as standard, our in-house designed iPM motor technology, and advanced connectivity. The result is a compact compressor that fits in the smallest room and that sets a new standard in efficiency and performance for years to come.

Small Models, Great Wisdom

• 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
1) Reduced energy consumption by 50% on average compared to the current idling models.
2) Free Air Delivery (FAD) increase of up to 12%.

• Reliable
1) Low maintenance: fewer components,increased uptime.
2) Based on the unique combination of proven technologies and existing components,optimally brought together by Atlas Copco’s experience and know-how.

• Smart
1) Easy monitoring and maintenance thanks to the Elektronikon® Touch controller.
2) Maintenance notifications and machine status are available via SMARTLINK e-mail or text messages.
3) Customized reports on the energy performance of your machine, in compliance with ISO 50001.
