Product Overview
The Atlas Copco GA22 integrates a 22 kW (30 HP) electric induction motor with a gear-driven oil-injected rotary screw pump to provide a consistent 135 CFM (3817 LPM) airflow. Engineered for continuous industrial duty, this stationary unit manages thermal protection and overpressure through a specialized smart controller and digital display. Operating on a 380-415 V three-phase supply at 60 Hz, the GA22 is housed in an industrial steel enclosure with noise insulation that keeps sound levels at 74 dB(A). The base mount design allows for optional tank integration, while the moisture separator ensures high-quality air for pneumatic networks. With a weight range of 410–485 kg, this compressor is built for permanent installation in manufacturing environments requiring 63.3 l/s of air at 8.5 bar.

Engineering Analysis
The GA22's gear-driven transmission is specifically matched to its 22 kW motor to eliminate the energy losses often found in belt-driven systems, ensuring maximum torque transfer to the rotary screw elements. This mechanical efficiency results in a free air delivery of 135 CFM, which is critical for maintaining stable pressure in complex industrial air networks. By utilizing an oil-injected lubrication system, the compressor achieves effective cooling and sealing of the screws, allowing for a 100% duty cycle without thermal degradation. The 74 dB(A) noise rating is achieved through internal noise insulation and anti-vibration mounts, making it suitable for point-of-use installation near workstations. The inclusion of a moisture separator and low oil shutdown protection prevents downstream contamination and mechanical failure, while the 380-415 V three-phase electrical configuration supports the high-torque demands of manufacturing workshops.
