The characteristics of the Roots vacuum pump are: quick start, low power consumption, low operation and maintenance cost, high pumping speed, high efficiency, and insensitivity to a small amount of water vapor and dust contained in the pumped gas, within a pressure range of 100 to 1 Pa. With a large pumping rate, it can quickly eliminate the sudden release of gas.
This pressure range is just between the oil-sealed mechanical vacuum pump and the diffusion pump. Therefore, it is often connected in series between the diffusion pump and the oil-sealed mechanical vacuum pump to increase the amount of pumping in the intermediate pressure range. It is also known as a mechanical booster pump.
