Variable Speed Drive(VSD)Rotary Screw Air Compressor

Greeknhi is able to provide GAVSD series,GA+VSD series,GM series and GM+ series compressors.With the GAVSD series and GA+VSD series featuring powerful operation and advanced techniques, which achieves a variable speed by PWM variable frequency drive (VFD), and the GM and GM+ series adopting a permanent magnet variable frequency drive (VFD) for variable speed, featuring reliable operation and easy maintenance.

Our variable speed drive (VSD) rotary screw air compressors feature a high efficiency and a better energy saving performance when compared with other traditional air compressors.

GM Series PM Motor Single Stage VSD Rotary Screw Air Compressor

Greeknhi's GM series compressor combines permanent magnet motor with a specially designed screw rotor, increasing the compressor's efficiency up to 10%-15% when compared with an asynchronous motor with the same specifications.

GM+ Series PM Motor Two Stage Variable Speed Rotary Screw Air Compressor

Greeknhi's GM+ series compressor combines the two stage compressor air end and permanent magnet variable frequency motor, which ensures a higher efficiency and longer life expectancy of the equipment, as well as saves energy during operation. It is widely used in machine manufacturing and processing industries, construction sites and other locations.

GAVSD Series Variable Speed Rotary Screw Air Compressor

There are two operating modes for Greenair's GAVSD series compressor.If the inverter is broken,change it to fixed speed mode,and repair the inverter without stopping the compressor.

GA+VSD Series Two Stage Variable Speed Rotary Screw Air Compressor

Greeknhi’s GA+VSD series compressor use two stage air end and high efficiency four-pole motor,equipped with high quality converter.Ensure you a lower energy consumption.
