Description
Atlas Greenair's GA+ series air compressor combines a two stage air end and oil free lubrication system, which is more efficient and produces air output up to 12-18% when compared with the single stage compressor under the same power conditions.

Energy saving air end
The two stage air end can produce more air when compared with the single stage one with the same power. The two stage air end combines a single stage and two stage compressor rotor into an enclosure with a direct drive front gear in order to achieve an optimum linear velocity that matches the air output during each stage's rotor operation.

Subsided air inlet valve
For Atlas Greenair GA+ series compressor, a gravity-inducted back-pressure valve is used as the air inlet valve, which prevents oil blowout from the air end and reduces air intake resistance.

High polymer filter paper
TheAtlas Greenair GA+ series lubrication system is designed with a highly efficient oil-gas separator filter element, which can remove oil impurities, lower compressor wear and ensure a long lifespan up to 4000-8000 hours.

Intelligent control
TheAtlas Greenair GA+ series comes with a RS485 communication interface, through which computer remote communication control and simultaneous control of several compressors is achieved.

Soft starter
With this soft starter, the instantaneous current generated as the motor starts is significantly lowered, thus protecting the motor and other compressor parts, ensuring there is less load and wear on the compressor.

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.

Side-mounted cooler
It is a highly efficient cooling system designed specially for clients in tropical areas to keep them away from compressor shutdown difficulties caused by high temperature operation of the machine.
