Vacuum blower aggregates

  As with the standard model, here are also available 20 sizes of ROOTs blowers to operate in vacuum mode at two levels.


  • Pneumatic conveying
  • Exhaustion and transport of non-explosive and nonaggressive gases
  • Industrial central vacuum cleaners
  • HVAC

Main advantages

  Total conception of arrangement of the aggregate is designed with emphasis on maximum reliability and functionality, easy checking, maintenance and accessibility of individual components of the unit in the acoustic cover

  • Low operating costs
  • User friendly design
  • Minimum built up area
  • Low noise
  • Long service life
  • Extra fast customer service
  • Identical dimensions and connections as a standard overpressure units = cost reduction and unification of production
  • No need of using additional ventilator for cooling of acoustic cover
  • Transported medium is free from oil.
