The VAV damper HLBx.. is used for fast and precise air volume flow control of contaminated exhaust air in fume hoods

  • Low pressure loss
  • Differential pressure process by Venturi orifice
  • Reliable measurements event at low volume flows
  • High control accuracy (±5%)
  • Ultra short form (HLBHA...) and short form (HLBAA...)
  • Flange connection
  • No cleaning of pressure pickups necessary
  • Low-maintenance construction
