Atlas Copco Oil-injected Rotary Screw Air Compressors (Model GA 30+-90/GA 37-90 VSD)30-90 kW/40-125 hp

  Atlas Copco Oil-injected Rotary Screw Air Compressors(Model  GA 30+ GA 37 GA 37+ GA 45 GA 45+ GA 55 GA 55+ GA 75 GA 75+ GA 90 GA 37 VSD GA 45 VSD GA 55 VSD GA 75 VSD GA 90 VSD )


1.Maintenance free drive system

- The GA drive system is 100% maintenance free – eliminating the risks inherent to the greasing of conventional motor bearings.

- Patented technology allows the drive system to run in ambient temperatures up to 55°C/131°F.*


2.Oil filter

- A high efficiency oil filter removes 300% smaller particles than a conventional filter, providing clean oil to extend the lifetime of all lubricated parts in the compressor.

- The oil filter rating of ß12=75 sets a new industrial compressor standard that is fully compliant with ISO 16889.  


3.Aftercooler with integrated water separator

- The GA’s aftercooler with integrated water separator immediately removes 100% of condensate – avoiding the risk of corrosion in downstream equipment and improving air quality compared to conventional cyclone separators.


4.Electronic water drains

- The GA’s no loss drains eliminate the waste of compressed air that conventional drains create.

- The drains communicate with the compressor controller to ensure the constant removal of condensate.

- A large diameter drain port removes the potential for clogging, providing trouble free operation.


5.Electrical cubicle cooling booster

- The main cooling fan cools the electrical cubicle, ensuring operating temperatures are strictly regulated even in ambient temperatures up to 55°C/131°F.*


6.Oil separator

- Innovative filter material removes oil particles from the compressed air while minimizing pressure drop. This results in optimal air quality at the highest efficiency.


7.Inlet valve

- The inlet valve is sized for maximum flow to eliminate any inefficient pressure drops.

- The valve is operated through vacuum and air pressure to offer superior reliability compared to spring operated inlet valves.


8.Inlet filter

- A heavy duty air intake filter protects the compressor components by removing 99.9% of dirt particles down to 3 microns.


* Standard up to 46°C/114.8°F, optional high ambient version up to 55°C/131°F.
