Rotary Screw Compressor

Atlas Copco recently introduced the oil-injected rotary screw compressor from 7 to 37 kW: the 7-37 GA VSD+. This new type of compressor offering a variable speed (frequency-controlled), will be suitable for most industries and aims to contribute to the green economy needs. It will enable all compressor users to switch over to variable speed drive compressors. The supplier evaluated every part in this compressor: a more efficient fan, robust air intake system, eliminating all blow-off losses, and the best 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. The new compressor is another 15% more efficient than Atlas Copco's current Variable Speed Drive compressor (theGA 7-37 VSD). A full feature version with an integrated dryer is available as option.
