Dry Roots Pumping Stations - Pfeiffer Vacuum

Dry Roots Pumping Stations

In applications where a high pumping speed is required, the pumps from the HeptaDry series can be combined with the OktaLine series roots pumps in a modular design with numerous options.
  • Oil-free pumping station consisting of an OktaLine roots pump and a HeptaDry pump
  • High pumping speed for fast evacuation times from 450 up to 3600 m3/h
  • Higher pumping speeds on request

Pfeiffer Vacuum supplies dry roots pumping stations which combine roots pumps with multi-stage backing pumps. The high pumping speeds afforded by these pumping stations enable a low end pressure to be achieved.

Dry roots pumping stations are state-of-the-art solutions for demanding industrial processes, such as the semiconductor industry. Pumping stations with reduced protective equipment can be used where process requirements are less stringent, for instance in load lock applications or as backing pumps for sputtering processes. We can supply everything from solutions for small vacuum chambers right up to maximum throughput in solar technology and display panel manufacturing.
