More info
Model HL2/90 is a two stage 90º V-compressor. ( typical data )
Cylinders and compressed air coolers are air-cooled. Cooling air is supplied by a well-dimensioned fan.
Bearings and cylinders walls are splash lubricated.
The compressor and motor are normally supplied mounted together on a foundation, and connected by means of a heavy-duty flexible coupling.
