Simplicity of design with only one shaft and direct drive produces robust, long-lasting vacuum pumps with low maintenance and running costs. These vacuum pumps operate completely oil-free; the individual chambers are separated by long-life vanes. Already featuring integrated intake filters and control valves, these vacuum pumps can be fitted with other accessories without a problem. The compact cover ensures low noise and heat emission. Optional corrosion protection also makes these vacuum pumps suitable for
extracting moist air.
The frequency inverter integrated in the VARIAIR UNIT significantly enhances the performance data of rotary vane vacuum pumps. It matches vacuum pump delivery exactly to customer requirements. Energy consumption is optimised and constant vacuum is guaranteed even where demand is subject to Variation or severe fluctuation.
As no unnecessary suction air is generated, noise is kept to a minimum. Dirt from the surrounding environment is kept out of the vacuum pumps. "Gentle" vacuum-pump start-up reduces strain on mechanical components and reliably extends their useful life.
Variable Output ranges minimise the number of different types required, thus also providing logistical advantages.
