1 Product overview
GD300-21 air compressor integrated machine is capable of providing dual inverter output of master
and fan for the air compressor as well as of24V power to the touch screen. It supports control
of solenoid valve and receiving of temperature and pressure signal. In respect of function, it is a
perfect replacement for the original dual inverter electrical control cabinet of air compressor but with a
much smaller size and simpler installation and debugging procedures.
