Rotary vane pressure/vacuum pumps, oil-free

Simplicity of design with only one shaft and direct drive produces robust, long-lasting pressure/ vacuum generators compressors with low maintenance and running costs. These pressure/ vacuum generators operate completely oil-free; the individual chambers are separated by long-life vanes. Already featuring integrated intake filter and control valve, these pressure/vacuum generators can be fitted with other accessories without a problem. The blast air cooler, which is also integrated, guarantees a very low blast air temperature. The compact cover ensures low noise and heat emission. The combined pressure/vacuum generators are additionally equipped with a second intake. This provides the capability of making minor adjustments to the suction and pressure side as well as to high blast air volumes. By way of option, the second intake can also be used as a second low-vacuum suction air supply. Optional corrosion protection also makes these vacuum pumps suitable for extracting moist air.

Side channel pressure/vacuum pumps

Using "multi-stage" compression, side channel pressure/vacuum generators produce low-pulsation suction and blast air. Perfected impeller design with curved blades guarantees optimum efficiency. Separation of the compression chambers on both sides of the impeller provides the capability of operating with a combination of suction and pressure with only one impeller. Intake filter, vacuum as well as pressure safety valve can be integrated as an optional extra in the patented design of the sound absorbers. The sound absorbers can be varied in length, affording flexible adjustment to available installation space.
