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 

by INVT 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.

Power range:

Three-phase 220V (-15%) ~ 240V (+10%) 7.5~45KW

Three-phase 380V (-15%) ~ 440V (+10%) 15~90KW


Product feature

1. Dual frequency conversion drive and control in one

The main engine and oil temperature fan are dual frequency conversion drive and control in one, which makes the control more intelligent and the 

air compressor more energy-saving and efficient.


2. Dual-stage dual-drive control

The integrated unique dual-drive constant pressure control algorithm makes the dual-stage dual-drive air compressor always run in the best operating state.


3. Integrated integrated design

The functions and configurations are highly integrated, which reduces the customer's electrical cabinet assembly time by 80%, greatly reducing the customer's 

product material cost and manufacturing costs.


4. Stable and reliable

Design, testing and production are strictly carried out in accordance with IEC international standards to ensure the reliable operation of the product in various 

harsh environments.


5. Smart Internet of Things cloud platform

The optional 4G Internet of Things data terminal can be connected to the air compressor dedicated Internet of Things cloud platform to realize real-time detection 

of operating status, maintenance reminders, fault alarms and intelligent analysis, remote maintenance, intelligent management of equipment operating status, 

equipment energy efficiency data analysis and other functions; in addition, it supports customized deployment of private cloud platforms, with diversified choices 

and good data confidentiality.
