Sullair Air Compressors


Sullair air compressors are rotary screw compressors. The company manufactures what they call Stationary Power, Portable Air Power and OEM type air compressors. Looking for information on Sullair compressors, or a forum for troubleshooting. You have arrived at the right site. Read on.

Within their Stationary Power line, they offer the industrial and manufacturing markets compressors, dryers, and other accessories to help delivery compressed air to those markets.

They are also big in what they term as Portable Air Power, and by that they mean what I refer to as Tow Behind type air compressors like the model 750 H shown in the photo.

For those looking to have a compressor manufactured for them, Sullair compressors offers their OEM line and they will build a compressor to suit your application.
