Transairvac are the official distributor in the UK & Ireland for Baratti roots blowers.

These Bi-Lobe roots type positive displacement blowers have a specially designed rotor profile and discharge port, which allows an extension to the pressure range of a normal roots type blower.

These design features mean it can achieve 1.6Barg at pressure and 700mBarg at vacuum.


Baratti Bi Lobe roots blowers are used for many applications such as aeration, gas boosting and pneumatic conveying.

Typical applications are:

  • Tanker discharge
  • Aeration
  • Pneumatic conveying (pressure & vacuum)
  • Process industry


  • Highly efficient; saves 10% energy cost
  • Constant discharge temperature
  • Specially designed rotor profile and discharge port
  • Low noise level; approximately 10db(A) quieter


  • ISO approved
  • ATEX certification
  • Bi Lobe ‘gamma’ design
  • Increases the range of capacity (turn down) of 20%-100% of the blower capacity
  • Single stage blowers can compress up to 1.6bar overpressure or 300mbar abs.vacuum
  • Reduces discharge pulsation by approx 85%
