GA+VSD Series Two Stage Variable Speed Rotary Screw Air Compressor
Product description
GA+VSD Series Two Stage Variable Speed Rotary Screw Air Compressor
Two stage compressor air end
This two stage compressor lowers the compression ratio compared with a single air compressor, reduces air leakage, bearing load and ensures a longer life service and volumetric efficiency of the air end. With our optimization, bearings have a life span of over 150,000 hours, and low noise, low vibration, safe and reliable operation is ensured.
Four-pole motor
As the motor speed is relatively low with 1480RPM (50HZ) as compared with that of the two-pole motor, there is air compressor wear and a longer service life.
Intelligent control system
Atlas Greenair's GA+VSD series intelligent control system is able to conduct remote control through computer interface and achieve simultaneous control for multiple compressors.
Split type
The air end and motor is connected separately, which is easier for installation, dismantlement and maintenance.
Backward curved centrifugal fan
An optional backward curved centrifugal fan uses an impeller to increase air flow. In addition, during the operation the centrifugal fan features no friction, low noise, no dust and easy maintenance.
