Technical Specifications

Zebra RH 0030 - 0090 B

Rotary vane technology is synonymous with a robust, functional construction. Due to two-stage compression, an ulti-mate 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 gasballast valve allows condensable vapours to be pumped.


A non-return 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 24 to 95 m³/h outlined here, the Zebra series also includes models with lower pumping speeds from 3 to 21 m³/h.
