Mark MSS
Base-mounted fixed-speed screw compressors for steady 7-10 bar industrial air.
A straightforward fixed-speed screw platform.
A practical fixed-speed screw range from 4 to 75 kW for steady 7–10 bar industrial air.
It suits factories with stable air demand and a preference for straightforward compressor-room maintenance.
- Asymmetric screw airend for efficient, low-pulsation air.
- Base-mounted layout with a simple controller and accessible service points.
- Specification table verified from source material.

Atlas HS fixed-speed screw air for value-focused factory installations.
A compressor needs clean, dry air downstream.
Treat condensate, oil carryover and particulates before they reach tools, valves or the final product.
- Dryers for +5 C or -40 C dew point targets.
- Filters for particulate, oil aerosol and vapour polishing.
- Receivers, auto drains and separators to stabilise the whole room.
