Screw compressors

New from Atlas Copco Compressors is a 30-90kW oil-injected screw com - pressor range which offers significant improvements in sustainability and reliability, as well as performance increases of up to 10%. The new GA 30+ to 90 range is available in three variants making it suitable for a wide variety of applications.

The GA 37-90 VSD models are said to deliver on average 35% energy savings, while avoiding compressor idling time. The premium efficiency fixed speed Plus variant GA 30+-75+, has IE3 motor and, says the company, best in class Free Air Delivery (FAD).

The standard base performing GA 37-90 completes the range.

Thanks to the improved component lay-out in the canopy, temperatures at the element outlet are down by 10°C/18°F. Atlas Copco also introduced IE3 premium efficiency motors, combined with highly efficient screw elements in all ranges.
