This  TEKVAC  Vortex Blower  are suitable for all those applications requiring considerably higher pressures than those can be achieved using centrifugal fans. Side channel exhausters are used in all those applications requiring an operating vacuum higher than the one achievable by a fan. The rotating parts are not in contact with the casing. therefore, no friction during operation, and thus no internal, lubrication is necessary. Gas moving through the machine, therefore remains uncontaminated and completely oil-free.
The other main features as follow:
1) Beautiful surface
2) Easy installation
3) Low noise level
4) No vibration, and therefore complete dynamic stability
5) Pulsation-free discharge
6) Minimal maintenance
7) Higher pressure ratio
8) Cooler running bearings
9) Longer grease life
10) Simple maintenance
11) 100% oil-free air
12) Suitable for environmental protection
13) Small dimensions
