Atlas Copco′s GA compressors bring you outstanding sustainability, reliability and performance, while minimizing the total cost of ownership. A choice of two premium compressor types (GA VSD+,GA+ and GA) provides you with the compressed air solution that perfectly matches your requirements with clear value propositions.Built to perform even in the harshest environments, these compressors keep your production running efficiently.
GA 11-30 High-Performance Compressed Air System
The upgraded Atlas Copco GA 11-30 air compressor delivers energy efficiency that meets the requirements of Grade 1 under China’s GB 19153-2019 standard, while providing significantly increased air delivery.
Low-noise operation makes it ideal for point-of-use applications.
FF models feature an integrated air dryer that delivers high-quality compressed air with a pressure dew point of 3°C.
The Elektronikon® touchscreen controller provides easier human-machine interaction and more precise compressor control.

High-Efficiency Motor and Drive System
The Atlas Copco air compressor features a proven proprietary drivetrain and high-efficiency gearbox, delivering exceptional reliability for continuous industrial operation.
Equipped with an energy-efficient IE3 or IE4 motor, it uses lifetime grease-lubricated motor bearings to reduce maintenance requirements and minimize operational concerns.

Newly Designed Electrical Control Cabinet for Extended Service Life
The Atlas Copco air compressor features a forced-cooled electrical control cabinet that further reduces internal temperatures, helping extend the service life of electronic components and improve long-term operational reliability.
Elektronikon® Touch for remote monitoring
High-tech controller with warning indications, compressor shut down and maintenance scheduling.
Easy to use and designed to perform in the toughest conditions.
Standard SMARTLINK remote monitoring to maximize air system performance and energy savings.
Optional multiple compressor control (2, 4 or 6 compressors).

Complete Compressed Air Solution
The integrated air dryer features a counterflow heat exchanger and built-in water separator, with intelligent dryer control that adjusts operation according to the air compressor load.
A dedicated cooling fan, high-efficiency cooler, and integrated dryer with a 3°C pressure dew point help prevent condensation in the compressed air network and reduce the risk of pipeline corrosion.
The water separator in the aftercooler removes most of the moisture, while the standard electronic drain automatically discharges condensate and minimizes compressed air loss.
Optional air filters can reduce the oil content in the compressed air to below 0.01ppm.
Innovative Cooling Fan
The latest fan technology reduces energy consumption while effectively controlling operating noise, helping the Atlas Copco air compressor deliver quieter and more energy-efficient performance.
