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 offering +24V 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.
