More info

Capacity at 50 / 60 Hz: 59 m³/h at 1170 rpm (60 Hz) according to the nameplate. On 50 Hz the speed is approx. 975 rpm, which gives approx. 49 m³/h. 60 Hz gives 20 % higher speed than 50 Hz, and thus approx. 20 % more air (theoretical, capacity follows speed). The Exico motor is rated for both 50 Hz and 60 Hz.

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.
