Robust & efficient compression element

Atlas Copco’s trusted rotary screw element ensures our G compressors’ high free air delivery and supreme reliability.

Delayed Second Stop

Increase your compressor’s efficiency with the Elektronikon®’s Delayed Second Stop (DSS). It stops the compressor’s motor whenever possible (while maintaining the desired system pressure) to minimize motor run time and your energy consumption.
