Description

GA 30⁺-75⁺: Industry-leading efficiency

The GA 30⁺-75⁺ sets the standard in fixed-speed oil-injected rotary screw compressors. It gives you more of the things that really matter: more energy savings, more air, and a longer lifetime thanks to its unique smart features:

  • Maintenance-free drive system performs reliably in tough, hot conditions up to 46˚C/115˚F.
  • IE4 Super Premium Efficiency motor maximizes energy savings while decreasing your environmental impact.
  • Unique Smart Thermostatic Control System (GA 55⁺/GA 75⁺) achieves ideal injection temperature to improve efficiency and reliability.
  • Intelligent sensors constantly monitor the pressure drop in the inlet filter, the oil separator, and the oil filter (optional) to minimize energy losses.
  • Elektronikon® Touch controller and SMARTLINK offer advanced, remote control, monitoring and performance optimization.

The GA 37-90 gives you that trusted Atlas Copco oil-injected screw performance at a low investment cost.

  • Maintenance-free drive system performs reliably in tough, hot conditions up to 46˚C/115˚F.
  • IE3 Premium Efficiency electrical motor is designed for continuous operation.
  • Elektronikon® controller and SMARTLINK offer advanced, remote control, monitoring and performance optimization.

The Smart Temperature Control System calculates the ideal oil-injection temperature based on parameters such as ambient and oil temperature, pressure and load, and air humidity. When necessary, the STC valve routes the oil via the coolers to achieve that ideal temperature to maximize compression efficiency and eliminate any risk of condensation.

Use your compressor twice

As much as 90% of the electrical energy used by a compressed air system is converted into heat. Why let that heat go to waste? A specifically developed energy recovery system can be built into your GA⁺, allowing you to recover up to 75% of that power input as hot air or hot water (e.g.: changing room showers).
