DESCRIPTION

DOWNLOAD

Model, FID PRO, low-resistance cut-off dampers are designed for use in comfort ventilation installation, in points of penetration of these installations through vertical and horizontal building partitions. They are installed in systems 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

  • Low flow resistance
  • Nipple or muff variant
  • Installation in walls and ceilings
  • Optional making in EX variant
  • Operating reliability up to 10000 cycles

DIMENSIONS

 

NOMINAL WIDTH (Ø) From 100-315 mm
