mcr 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.
Cut-off dampers of fire resistance independent from direction of air flow and of installation side. Reduced acoustic noise and hydraulic resistance in the system due to reduction in thickness of the barrier.
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.
