The Roots pumps in the HiLobe and OktaLine series can be tailored, with different pumping speeds and versions, to perfectly meet customers’ requirements – and are also available as Roots pumping stations. The HiLobe, as the latest generation of pumps, provides maximum performance combined with minimum space requirements, and offers innovative features such as integrated individual speed control and very high short-term differences in pressure for fast cycle times. In addition to a very wide range of pumping speeds, the OktaLine has one of the best compression ratios on the market, for achieving the lowest ultimate pressures. These pumps require a backing pump that is suitable for the specific application and gas flow. Pfeiffer Vacuum will be pleased to advise you on the design.
