Technical specifications
Rotary vane technology is synonymous with a robust, functional construction. Due to two-stage compression, an ultimate total pressure of 6.7 · 10-3 hPa (mbar) is achieved. While the oil mist separator ensures clean and oil-free exhaust air, the inlet filter protects the vacuum pump against dust and other solid particles. Furthermore, the gas-ballast valve, which is integrated as standard, allows condensable vapors to be pumped. A nonreturn valve at the exhaust prevents oil from flowing back into the compression chamber after the vacuum pump is switched off. In addition to the four pump sizes from 3 to 21 m3/h outlined here, the Zebra series also includes models with higher pumping speeds from 30 to 90 m3/h.
