Atlas Copco introduces new 30 – 45kW compact compressors

Atlas Copco introduces new 30 – 45kW compact compressors Atlas Copco has now introduced three new models in its 30-45kW range of GA oil-injected rotary screw compressors. The new compressors offer full integration of air and condensate management, low-noise operation and occupy the minimum footprint at the point of use on the production floor. All three models are available as 7.5, 8, 10, and 13bar pressure variants. For performance and capacity comparison at a working pressure of 7bar, the GA 30+ offers a FAD of 96 l/s (203 cfm), the GA37 delivers 107 l/s (229 cfm), and output from the GA45 is 129 l/s (270 cfm). The new compressors feature an extreme-duty gearbox that is maintenance free and designed to run in the toughest of ambient conditions (up to 55°C). The gearbox is totally enclosed and provides performance efficiency that is equal to direct drive concepts. Another specific innovation is the compressors’ built-to last unloaders whose modulating force is pressure and vacuum, so there are no big heavy springs. This simpler design means fewer parts and greater reliability from units optimised for lower pressure drops
