Fire dampers are a crucial aspect of passive fire protection, helping prevent the spread of fire and smoke and providing sufficient time for safe evacuation. But, as with any safety apparatus, these fittings must be regularly tested and maintained by an air hygiene specialist to ensure they can effectively do their job should a fire break out. Whether you’re based in Camberley or elsewhere in the UK, it’s important to conduct proper fire damper testing and maintenance, as without it, they are likely to fail, which could have legal implications for your business.

Our services include:
Fire dampers are an important element of a building’s ventilation system and are installed where air-handling ducts meet fire-separating elements. They are placed within a duct and share the appearance of a metal curtain, held in place by a thermal element released when melted by a set temperature rise. The thermal element is forced closed by the release of a spring-operated metal curtain, filling the opening through which the duct passes and preventing the spread of fire.
A fire damper drop test consists of the following steps:
The fusible link is manually released, forcing the curtain to drop into the closed position.
Our air hygiene specialists ensure the curtain fully closes, visually checking that the bottom curtain blade locks onto the ramp.
The fire damper inspection continues with the fusible link checked for deformity or damage.
Whilst in the closed position, the fire damper cleaning begins, with lubrication applied if required.
The fire damper testing continues with the element being opened and reset, ensuring the bottom blade remains parallel to the damper’s top.
Photographic evidence is taken of the damper in the ‘as found’ position, closed position, and reset position, and our Camberley-based specialists create a report from our findings.
