Model LL2/90A is a one stage 90º V-compressor.

Cylinders and compressed air coolers are air-cooled.

Bearings and cylinders walls are splash lubricated. The compressor and motor are normally supplied mounted together and connected by means of a heavy-duty flexible coupling.

Both electrical and diesel engine driven versions are available.
