Matching your specific requirements

Our GA oil-injected screw compressors bring industry-leading performance, flexible operation and high productivity, reduced enargy costs at a minimal cost of ownership. A wide range of compressors enables you to find the air solution that perfectly matches your specific requirements. Built to perform in even the harshest environments, an Atlas Copco GA keeps your production running efficiently.

Atlas Copco’s VSD⁺ technology closely follows the air demand by automatically adjusting the motor speed to match the compressed air supply to the demand. Combined with the innovative patented iPM (interior Permanent Magnet) motor (IE4), the GA VSD⁺ achieves average energy savings of 50%. This reduces the total lifecycle costs of the compressor up to 37% on average. On top of energy savings up to 50% , the GA VSD⁺ realizes a Free Air Delivery (FAD) increase of up to 12% for improved efficiency and performance.
