The PGW HL 50/100/00 is a single stage radial compressor with a variable inlet guide vane, which allows for investigates of mass flow meters (e.g. orifices, venturi tube, etc.). It provides a versatile air supply due to its variable speed drive (200kW DC motor, 0-3000 rpm with a planetary gear drive, ratio 1 : 6,882) and an air-water heat exchanger at the outlet for temperature control. The maximum pressure ratio is 2.
