Highly efficient cooling system
Greeknhi's GA series air compressor is designed with an operating temperature of 55℃, similar to a tropical desert environment. This series features an improved cooling system for controlling the operating temperature of the unit cooler, thus ensuring the air compressor will not fail during high temperature operations.

Three stage oil-gas separator
This three stage oil-gas separator is made independently by Greeknhi and has won a national patent. It includes three stages: centrifugation, sediment and filtration. It can provide high quality compressed air with an oil content less than 2ppm.

Original air end with large air capacity
The air compressor is equipped with asymmetric male and female rotors and they have two prominent advantages over the other rotors:

As the gear tooth profile of the rotor consists of an arc and arc envelope, a "convex-concave" seal is achieved between the rotors, which helps to produce hydrodynamic lubricant film and make the compressor more efficient.

Speed of this air compressor is 30-50% lower than that of other air compressors, due to the large rotor and bearing. The rotor and bearing also reduce noise, vibration and effects caused by impurities and carbides on the rotor and ensures a longer service life.

High quality air end bearing
Greeknhi GA series compressor uses SKF bearings. It features a stable operation and is applicable to variable working conditions, ensuring the motor a longer service life.

Highly efficient drive system
It is an integrated drive system without a gear. Using a 1:1 direct connection drive, there is no production loss, making it an ideal drive system. It combines the motor, coupling box and air end as a whole to ensure compressor efficiency and center alignment of motor and air end when they are installed or during operation.

Control system
An intelligent control system means operation does not need to be supervised, and there is automatic power on and off, compressor failure alarm and shutdown and maintenance deadline alarm, making the compressor well-operated.

Special motor for air compressor
The highly efficient motor meets IE3 standards with an energy efficiency up to 93%.
