Model, FID S/S p/P, FID S/S p/O cut-off dampers are designed for installation in general ventilation systems, at the point of penetration of these installations through building partitions.
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
- Damper reinforced with insulating interlayer
- Bracing-reinforced barrier - increased mechanical strength
- Large dimensions – up to 1.8 m2
- Installation in walls and ceilings
- Installation outside building partitions
- Installation in batteries (damper sets)
- Optional making in EX variant
- Operating reliability up to 10000 cycles
