The Q-70L incorporates CompAir?s patented Q-drive compression and motor assembly, which uses magnetic bearings to stabilise the rotor shaft. The shaft is supported in a magnetic field while spinning at 60,000 rpm and since there is no contact, there is no wear and tear on surfaces, thereby increasing its operational life.
The Q-drive system also features an asynchronous induction design, removing the need for a conventional gearbox. This means no need for oil in the compressor and so no risk of oil contamination.
Variable speed technology used in the Q-70L matches output to the exact requirements to maximise off-load running.
Energy savings of up to 25 per cent can be achieved at 2.5 per cent of full load power, which means lower running costs and a better environmental footprint.
Noise levels for the compressor are low at 69 dB(A), it has a rating of 300 kW, and a minimum working pressure of 3 bar(g).
