Rectangular single blade externally resettable combination fire and volume control damper designed to prevent the spread of fire and smoke through rectangular ducts.
Application
For internal use in buildings:
- To be installed in rectangular ducted HVAC systems within fire boundaries.
- Suitable for use in dryline walls and masonry/concrete walls and floors.
Description
The FD-R Series Mechanical Rectangular Fire Damper with volume control facility has been designed specifically for installations where space is limited. The testing and resetting of the damper and thermal fuse external of the duct allows for ease of commissioning and maintenance.
The angle frame, with its integral fixing holes, acts as a template to allow the marking of the fixing positions on the surface of the structure to which the frame will be affixed, allowing for a quick and efficient install. Manufactured from galvanized steel, it comes in a range of different sizes to suit various applications.
