Select a product
Pyrocheck Series PA fire dampers can be mounted horizontally, vertically without effect on their operation.
The design of Pyrocheck Series PA presents minimal obstruction to the air flow during normal operation (prior to initiation), consequently the pressure drop across the damper is extremely low.
The precision low mass fusible link is set to operate at 72°C Operation of the fusible link releases the blades and completely blocks the duct. A feature of the PA damper is its’ duct sealing ring and intumescent seal. This compensates for any minor irregularities in the duct which may otherwise create gaps between the duct wall and the damper.
Fire Rating
The pyrocheck range of dampers have been tested at Warrington Fire Research Centre. The dampers were assessed against the criterion for integrity as defined in BS476 Part 20 for 4 hours.
The dampers maintained their integrity successfully throughout the test, which was discontinued after 4 hours.
