VAKUUM BOHEMIA offers sale and servicing of Roots blowers. Roots blowers are used as central blower stations for air transportation. Blowers generate overpressure or negative pressure or both.

Operating principle of Roots blowers

During rotation, rotors do not touch each other or the stator. The vacuum pump is oil-free. Oil is only located in the gearbox and is not in direct contact with the medium. The stator contains two counter-rotating, three-tipped pistons. The medium is contained in the space between the rotors and the stator. It is compressed, pumped through the housing to the gas discharge by rotary motion, and discharged. Piston rotation is driven by a pair of gear wheels located on the shaft ends in the gearbox, separated from the compression chamber. 

Parameters of Roots blowers:

  • pumping speed: from 300 m3/h up to 10 000 m3/h
  • motor power: from 1.5 kW to 315 kW
  • max. underpressure: -0.8 bar
  • max. overpressure: +1 bar

Advantages of Roots blowers:

  • fault-free operation
  • long service life
  • possibility of control with a frequency converter
  • clean air without oil
