More info

Capacity at 50 / 60 Hz: 60 m³/h at 1170 rpm (60 Hz) according to the nameplate. On 50 Hz the speed is approx. 975 rpm, which gives approx. 50 m³/h. 60 Hz gives 20 % higher speed than 50 Hz, and thus approx. 20 % more air (theoretical, capacity follows speed). The HL2/120 is rated for max. 1500 rpm and uses a 6-pole motor.

Model HL2/120 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.
