Atlas Copco GA 30+–75+ Air Compressor Range

The Atlas Copco GA 30+–75+ range uses rotary screw compression for industrial compressed-air systems.

Performance and supplied equipment depend on the model, pressure setting and package configuration. QCAS can confirm the appropriate compressor and supporting equipment for the application.
