Roots Vacuum Pump
The characteristics of the Roots vacuum pump are: quick start, low power consumption, low operation and maintenance costs, high pumping speed and efficiency, and insensitive to the small amount of water vapor and dust contained in the pumped gas, relatively high pumping rate within the pressure range from 1~100Pa, can quickly ruled out the sudden released gas. The pressure range is between an oil-sealed mechanical vacuum pump and a diffusion pump, therefore, it is often connected in series between the diffusion pump and the oil-sealed mechanical vacuum pump to increase the pumping capacity of IP range. Also called as mechanical booster pump.
Roots vacuum pumps are widely used in vacuum metallurgy for smelting, degassing, rolling, as well as vacuum distillation, vacuum concentration and vacuum drying in the chemical, food and pharmaceutical industries. Vacuum pump accessories is silencer which used for noise control.
