Features

• Model HL2/90A is a two stage 90º V-compressor.
• 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.
• Both electrical and diesel engine driven versions are available.
