These blowers are suitable for all those applications. Considerably higher pressures can be achieved by using centrifugal fans. Side channel exhausters are used in all those applications requiring an operating vacuum higher than the one achievable by a fan, but not as high as to require the use of a vacuum pump. The rotating parts are not in contact with the casing. There is, therefore, no friction during operation, and thus no internal.
Lubrication is necessary. Gas moving through the machine, therefore it remains uncontaminated and completely oil-free.
