Product Details

GD300-21 series air compressor dual frequency conversion all-in-one machine is a special dual frequency conversion all-in-one machine designed 

and developed for synchronous or asynchronous twin-screw air compressors. It is used in conjunction with INVT's HMI touch screen to perfectly 

realize the drive and management of twin-screw air compressors. GD300-21 air compressor all-in-one machine can provide air compressors with 

dual frequency conversion outputs for the host and fan, provide +24V power to the touch screen, control the solenoid valve, and receive temperature 

and pressure signals. It completely replaces the original air compressor dual frequency conversion electrical control cabinet in terms of function. 

However, compared with the previous electrical control cabinet, the volume of the all-in-one machine is greatly reduced, and installation and 

debugging have become easier.
