About the series

Technology and features

Operating principle

Rotary vane technology allows a technically simple design of vacuum pumps. A consistently high vacuum level in continuous operation is ensured by the circulating oil lubrication, perfectly matched materials and modern, precise manufacturing techniques. The oil separator with integrated oil return provides clean, oil-free exhaust air. A further advantage over other technologies is the low purchase cost.
