New G Series: Durable Screw Compressors

 

Atlas Copco sets the benchmark for reliability and performance for the air compressor industry. The new G 4-90/G 55-75 V series is based on Atlas Copco's consistent customer commitment. Small users provide high-power, high-reliability screw compressors.

 

Reliable rotor and motor

 

• The rotor used in the G-Series air compressors is the most mature product of Atlas Copco

 

• G 4-22 V-belt efficiency is 2-3% higher than other belt drive systems

 

• G 30-90 gear drive system with unmatched reliability and longer maintenance intervals

 

Intelligent monitoring

 

• Integrated monitoring, control, and protection of air compressors

 

• High reliability, classic interface, durable buttons

 

• Elektronikon color screen computer controller to visualize compressor status (optional)

 

High-tech oil separator

 

• Prevent oil contamination: Thanks to the erect oil tank design, the oil content is extremely low

 

• Oil separator size is minimized and compressed air loss is extremely low during loading/unloading cycles
