Why the DX200 to DX355?
Particles, oil and oil vapour in compressed air can spoil products and trigger recalls. The DX series removes this risk while saving up to 7 % energy at fixed speed and up to 5 % at variable speed.
The coolers are designed for ambient temperatures up to 46 °C. Maintenance requires no special tools, and all parts are easily accessible.
- Up to 8 % more flow
- Up to 7 % (fixed) or 5 % (variable) less energy
- Turndown range up to 71 % on RS models
- UltraCoat coating, stainless steel rotors in the 2nd stage
- Operation up to 46 °C ambient temperature
- Air- or water-cooled, options for outdoor installation

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.
