Roots Blowers (aka Booster Pumps) - Vacaero

When used in a high or ultra-high vacuum system, the Roots blower is located between the primary pump and a diffusion (or other style) high vacuum pump. In this arrangement, a bypass is incorporated whereby the Roots pump and primary pumps operate with the high vacuum pump in bypass mode during the initial pump down (roughing) stage. ...<< more>>

Mechanical Booster Pumps for Vacuum Systems - Vacaero

If a Roots style vacuum booster pump was to be used as a single pump on a vacuum system (very unlikely), the compression ratio limits the best vacuum it can produce to about 38 Torr. (atm. press 760/20 = 38 Torr) This is not a low enough pressure for most vacuum applications. ...<< more>>

ZJ Roots Vacuum Pump - evpvacuum

ZJ Series Roots Vacuum Pump is a positive displacement pump, also known as mechanical booster pump, which is one of the main equipment to obtain the middle and high vacuum degree. Its working principle is similar to roots blower, which use two figure 8 rotor synchronous rotation in the pump shell, so as to complete the suction and exhaust process. ...<< more>>
