Atlas Copco 7-37 GA VSD⁺ rotary screw compressor

Atlas Copco has introduced a compact oil-injected rotary screw compressor from 7 to 37 kW: the 7-37 GA VSD⁺. The product offers improvements of up to 12% in free air delivery. High-quality electronic components, together with the new drive train, add up to energy savings of 50% on average compared to a traditional idling compressor of the same type.

Offering a variable speed (frequency controlled), the compressor will be suitable for most industries and aims to contribute significantly to the green economy needs. The variable speed drive compressor is said to achieve better performances even at full load than a comparable idling compressor. This will enable all compressor users to switch over to variable speed drive compressors.

The compressor features low noise levels, an efficient fan and a robust air intake system, eliminating blow-off losses. The product is said to be 15% more efficient than Atlas Copco’s current variable speed drive compressor (the GA 7-37 VSD). A full-feature version with an integrated dryer is available as an option.
