Roots booster vacuum pumps, or roots blowers are dry positive displacement pumps. They operate using the Roots operating principle, a working principle similar to rotary vane pumps. These pumps are the ideal solution when fast pumping speeds are required.
In combination with an oil-lubricated rotary vane vacuum pump, Roots booster pumps, or Roots blowers are often used in pumping stations to achieve a very high volume flow with a deep final vacuum.
