Model, WIP PRO/S, multi-blade cut-off dampers are both 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 damper 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.
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.
Features
- Small thickness of damper - 135 mm (Model WIP PRO/S)
- Cut-off barrier does not protrude outside the damper body, regardless of damper dimensions
- 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 10000 cycles
