Atlas Copco GA11-125 is a 15 HP oil-injected rotary screw compressor designed for continuous-duty industrial production. It delivers approximately 55 SCFM at 125 PSI with a 128 PSI maximum, making it the natural step up from the GA5/GA7 for mid-size shops, paint booths, fabrication, and CNC rooms with high air demand. The unit is air-cooled, uses a TEFC motor and V-belt drive, and is controlled by Atlas Copco’s Elektronikon Touch microprocessor. The GA11 FF (Full Feature) variant adds an integrated refrigerated dryer that produces clean dry air at roughly 37-50F pressure dewpoint, eliminating most downstream drying needs. Atlas Copco supports North American customers through a dense factory-authorized dealer network for service, fluids, and parts. The GA-Series is widely considered one of the longest-lived rotary screw platforms on the market, and the airend is covered by an extended warranty under the Package Care program.
