Fixed Speed Dry Screw Vacuum Pumps

The Atlas Copco DWS range of fixed speed dry screw vacuum pumps features an innovative design with variable pitch dry screws. Engineered to deliver clean and reliable vacuum flow, the DWS series are a robust series of dry vacuum pumps. The dry screw technology offers lower maintenance costs and are used in diverse industrial applications requiring no lubricants in the pumping chamber. At the heart of the DWS Dry Screw pump is the tapered variable pitch dry screw mechanism, quick pump-down times, high pumping speed and high tolerance for particulates are core benefits of the product.

Robust pumps for flexible systems
The DWS range is flexible to be fitted into kinds of vacuum systems, either light duty process in general industry or harsh applications in chemical/pharmaceutical.

Easy to configure dry vacuum pump
Configuration options for hazardous process environments are available and the pump can be easily customized to a dry vacuum pump system.

Lower energy consumption
The hybrid rotor design uses a combination of parallel and tapered rotor profiles, helping to optimize performance while limiting the footprint and power consumption.

Wide range of accessories
A wide range of accessories are available, including service kits, booster support kits and silencer kits.

Purge protection
Purge protection helps extend service intervals and prolong pump-life – the DWS is built to handle harsh contaminant ingress.

Variants available
Available in water-cooled and air-cooled variants. Direct and indirect air-cooled options are available with the DWS 200 and DWS 500 available exclusively as an air-cooled option.
