How it works
Why screw beats piston for continuous duty.
Twin rotating screws
Two meshing helical rotors draw air in and squeeze it along their length for smooth flow with no pulsation.
Oil-injected sealing and cooling
Injected oil seals rotor clearances, removes heat and lubricates before separation downstream.
Built for 100% duty
A screw compressor is designed to run all day with steadier pressure, lower noise and longer life than piston machines.
Downstream air quality
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.
