Nuclear Fire Damper

Simplicity in design delivers long-life reliability with the Wozair Marine Fire Damper (MFD) for Nuclear applications.

The stainless steel isolation seals, oil impregnated bearings and low leakage bearing assemblies prevent fire and smoke spread through ventilation systems.

Manufactured using modern CNC laser cutting and folding processes, with metal to metal blade tip and blade edge sealing arrangements to achieve exceptional performance without the aid of gasket materials.

The MFD holds a Certificate of Constancy of Performance and can be CE marked against the Construction Products Regulation.

The MFD is a tried and tested design, which has been supplied on hundreds of projects since 2003. It can be used in both safe and hazardous areas, and has a fully customisable design from simple control layouts to SIL2 compliant assemblies.
