Product Overview
The Atlas Copco GA11 utilizes an 11 kW (15 HP) motor to drive its oil-injected rotary screw pump, specifically designed for manufacturing plants requiring a 100% duty cycle. Delivering 35 CFM (990 LPM) of constant airflow, this model replaces intermittent piston units with a stationary, gear-driven system that manages heat through specialized oil injection. The 410–455 kg steel industrial enclosure is outfitted with noise insulation, ensuring the 63-68 dB(A) output remains compatible with localized workshop environments. Operating on a three-phase 380-415 V AC supply at 60 Hz, the GA11 includes a smart controller with self-diagnostics and a digital display to monitor pressure and service intervals. While the tank is an optional configuration, the base unit features anti-vibration mounts and a moisture separator to protect downstream pneumatic tools and air lines from contamination and mechanical stress.

Engineering Analysis
The technical superiority of the GA11 lies in its direct gear-driven transmission, which provides higher energy transfer efficiency than belt-driven 11 kW alternatives by reducing mechanical friction losses. The oil-injected rotary screw design allows for continuous run capability without the thermal degradation associated with reciprocating models, maintaining a stable 7.5 to 13 bar pressure range. By utilizing an 11 kW TEFC induction motor, the system achieves a 990 LPM flow rate while the integrated Elektronikon smart controller actively monitors thermal protection and overpressure sensors to prevent component failure. The 63-68 dB(A) noise rating is achieved through internal noise insulation and an air-cooled cooling type, which facilitates installation directly on the factory floor without requiring a dedicated compressor room. Furthermore, the inclusion of a moisture separator and low oil shutdown ensures the air quality remains consistent for sensitive industrial applications.
