Atlas Copco Rotary Screw Lubricated Air Compressors

GX Series Compact Screw Compressors

Our oil-injected rotary screw G/GX compressors are powerful and reliable industrial screw compressors. Built from high-quality components and materials, they provide a reliable source of high-quality air in temperatures up to 46°C / 115°F. The compressors are compact, flexible and available in various versions depending on size:

  • floor mounted
  • tank mounted
  • with or without integrated dryer

GA (VSD+) Series Oil-Lubricated Screw Compressors

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.

Energy Saving Compressor Solutions

Our larger compressors are all equipped with the Elektronikon® panel, minimizing energy costs through smart technology. We also have a basic controller on our smaller versions, allowing you smart solutions independent of your company size.

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.
