Capacity at 50 / 60 Hz: 27 m³/h at 1175 rpm (60 Hz) according to the nameplate. On 50 Hz the speed is approx. 975 rpm, which gives approx. 22 m³/h. 60 Hz gives 20 % higher speed than 50 Hz, and thus approx. 20 % more air (theoretical, capacity follows speed).

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.
