CompAir DX90 to DX160
Oil-free two-stage compressors 90 to 160 kW – fixed speed and RS
The new DX series from 90 to 160 kW offers up to 14 % more energy efficiency and up to 8 % more flow than the industry standard, with guaranteed air purity to ISO 8573-1 Class 0.
The DX90 to DX160 have fixed speed, the DX90RS to DX160RS variable speed. Both are available air- and water-cooled.
Motor power
90 to 160 kW
Pressure
4 to 10.7 bar
Flow rate
6.7 to 28.3 m³/min
Air purity
Class 0
Why the DX series?
A newly developed two-stage compression element provides up to 9 % more capacity. A separate air inlet supplies it with cooler air. The UltraCoat coating and stainless steel rotors in the second stage ensure a long service life.
The RS models have an IE5 hybrid reluctance motor, the fixed-speed models an IE4 motor, both in IP55. Variable-speed fans and the wide turndown range get the best out of every load.
- Up to 14 % more efficient, up to 8 % more flow
- Class 0 certified
- IE5 motor on RS models, IE4 on fixed speed
- UltraCoat coating against corrosion
- Zero-loss condensate drain, hydraulic inlet valve
- Air- or water-cooled

Frequently asked questions
What does oil-free to ISO 8573-1 Class 0 mean?
Class 0 is the strictest purity class for oil in compressed air. A compressor certified to it puts no oil into the air, neither as droplets nor as vapour. You therefore need no oil filters and no oil-water separator for the condensate, and the risk of contaminated products disappears.
Fixed speed or variable speed (RS)?
A fixed-speed compressor is most economical when it runs at a steady load. If your compressed air demand fluctuates during the day, a variable speed RS compressor continuously adjusts its delivery and saves electricity. On request, we measure your demand with a compressed air analysis and tell you what is worthwhile.
Can the waste heat be used?
Yes. Up to 94 % of the energy consumed turns into heat. With heat recovery you can use it to heat water or rooms. More on this under Heat recovery.
Who maintains the compressor?
We do. As the CompAir partner for north-western Switzerland, we maintain and repair your system with genuine spare parts and service kits. If your compressed air supply fails, you can reach our on-call service on 062 552 00 88.

Which compressor is right for your business?
Compressed air demand, pressure, operating times and available space determine the choice. We advise you, supply the compressor with air treatment, install the system and take care of service.
