Atlas Copco GA37 Air Compressor

Let's start by checking out what the Atlas Copco GA37 air compressor is, for the folks that don't know. The GA37 has been around for decades now, and is currently lumped into their GA15-GA37 category of rotary screw air compressors by Atlas Copco.

The '37' in GA37 typically refers to it having a main motor 37 kW power supply which is essentially 50 HP and provides compressed air at around 7.5 bar or 110 PSI up to that of the newer models in the 12.5 bar or 180 PSI range depending on the year, and the version of GA 37 you may have.

The latest models of the GA37 offer VSD+ drive enabling the compressor to run at variable speeds depending on the conditions and the load.

Over the years lots of folks have asked questions about the Atlas Copco GA-37 air compressor on this site, so this page is now that model forum. All questions and responses about the GA37 air compressor model will be now on this page only.
