Roots vacuum pump features are: fast start, Roots vacuum pumps offer less power consumption, operation and maintenance costs low wholesale price Roots pump, pumping speed, high efficiency, and insensitive to be pumping gas contained a small amount of water vapor and dust in the range of 100 to 1 Pa pressure greater pumping rate can quickly rule out a sudden release of gas. This happens in a pressure range between mechanical pump seals and diffusion pump. So Roots vacuum outlets, it is often in series between the diffusion pump and mechanical seal pumps, used to increase the range of the intermediate pressure exhaust volume. At this time it is called mechanical booster. Roots vacuum Main features: 1, in a wide pressure range (1 ~ 1 × 10 4pa) have relatively the pumping speed. 2, the pump chamber without oil, to avoid contamination of the oil vapor vacuum system. 3, small vibration, low noise. 4, a small mechanical friction loss, so the drive power is small. 5, easy to maintain and repair, low cost, high life.
