mcr WIP/S - multi-blade cut-off fire damper for comfort ventilation systems

Fire resistance class: EI60(v_e i↔o)S, E120(v_e i↔o)S

Certificate of constancy of performance 1396-CPR-0097.

Dampers certified for conformance with EN 15650.

Dampers are classified as per EN 13501-3 and tested according to EN 1366-2.

Declaration of performance 001-05-CPR-2015.

Optional EX making of dampers (as per ATEX directive) for applications in explosion hazard zones.

KDB ATEX 17.0616, EU Declaration of conformity 001-01-2017.

Cut-off dampers of fire resistance independent from direction of air flow and of installation side.

Fixed, narrow damper thickness, regardless of B x H dimensions.

mcr WIP/S multi-blade cut-off dampers are designed for use in general ventilation installation, in points 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.
