SINGLE BLADE LOW RESISTANCE CUT-OFF FIRE DAMPER FOR COMFORT VENTILATION
DESCRIPTION
SPECIFICATIONS
DOWNLOAD

Model, FID S/S c/P, low-resistance cut-off dampers are designed for use in general ventilation installations, in points of penetration of these installations through vertical and horizontal building partitions. The dampers are used, among others, for installations with increased acoustic requirements. During fire, they allow to maintain fire resistance of the building partition through which ventilation and air conditioning ducts run. They also prevent propagation of fire, smoke and fire gases to the safe part of the building.

 

When made for potentially explosive zones (EX variant), the dampers may operate in zone 1 (risk of explosion of gases inside and outside of ventilation ducts) and zone 21 (risk of explosion of dust outside ducts). The dampers conform to the requirements of group II category 2G and -/2D.

FEATURES

  • Reduced hydralic
  • Bracing-reinforced damper barrier - increased mechanical
  • Installation in walls and ceilings
  • Optional making in EX
  • Operating reliability up to 10000 cycles
