Model, WIP/T, transfer dampers and WIP/T-G pressure-relief dampers are designed for installation in fire and comfort ventilation systems. They are installed in fire partitions, without connecting ventilation ducts to them; they preserve fire resistance of building partitions during fire.

Model, WIP/T, dampers are used as transfer dampers. They feature mechanisms with thermoelectric activators or without activators, depending on the function. WIP/T-G dampers are used as pressure-relieving dampers, e.g. in gas extinguishing systems. This variant features mechanisms without thermoelectric activators.

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
• Possibility of using in gas extinguishing systems
• Optional making in EX variant
• Operating reliability up to 10000 cycles
