Their integrated oil mist separator ensures clean exhaust air. They are equipped with a frequency converter that enables them to be used worldwide with a single-phase input and identical pump capacity for 50 and 60 Hz, states the company.

A constantly high flow rate in the target pressure range, adjustable pumping speeds and low final vacuum contribute to the instrument’s reliable high performance. Long maintenance intervals and operating hours are ensured by the high oil volume in the pumps and their low oil temperature during operation.

According to the firm, the rotary vane pumps can increase the overall availability of the instrument through their high ruggedness and reliability. At the same time, they are easy to integrate due to their low noise level and efficient oil separation. Both the pumps are certified according to UL and IEC 61010.
