More info

Capacity at 50 / 60 Hz: 47 m³/h at 1750 rpm (60 Hz) according to the nameplate. On 50 Hz the speed is approx. 1450 rpm, which gives approx. 39 m³/h. 60 Hz gives 20 % higher speed than 50 Hz, and thus approx. 20 % more air (theoretical, capacity follows speed). The HL2/105 is rated for max. 1800 rpm, so it can run with a 4-pole motor on both 50 Hz and 60 Hz.

Model HL2/105 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 foundationand connected by means of a heavy-duty flexible coupling.

Both electrical and diesel engine driven versions are available.
