mcr WIP/S - MULTI-BLADE CUT-OFF FIRE DAMPER

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.

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.

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

• small thickness of damper - 140 mm
• cut-off barrier does not protrude outside the damper body, regardless of damper dimensions
• large active damper in the multi-plane dampers segment
• possible installation in a partition, on a duct ended with a duct cover
• optional making in EX variant
• optional making of dampers with penetrations for rounded ducts
• operating reliability up to 10 000 cycles

APPLICATION

• PRODUCTION HALLS AND WAREHOUSES
• LOGISTICS CENTERS
• PUBLIC BUILDINGS
• COMMERCIAL BUILDINGS
• RESIDENTIAL BUILDINGS

ADDITIONAL DESCRIPTION

Making variants:

• mcr WIP/S [BF...-T, BFL...-T, BFN...-T, EXBF] – fire cut-off damper for ventilation ducts, with actuator with return spring - closing and opening of damper using actuator

mcr WIP/S dampers are particularly useful in cases when a silencer, a pipe elbow or an air flow grate is designed in the system behind the damper.
