1 General Information
The AirSmart
ä
Generation 2 (G2) controller was designed specifically for use in Gardner Denver rotary screw
air compressors and is capable of controlling fixed speed air compressors which use traditional motor starters
as well as variable speed and modulating compressors. The microprocessor-based unit monitors all
necessary temperature and pressure points within the compressor in order to safely operate the machine and
satisfy user air demand. The Control Panel displays a comprehensive overview of the compressor status and
allows easy access to operational parameters such as pressure set points, alarm set points and language
selection.
