The FDR-3G is designed to provide effective passive protection. It has a compartmentalized design which prevents the spread of toxic gases, smoke and fire. The unit meets rigorous safety standards and has been designed and certified in accordance with EN 15650 and tested for EIS criteria according to EN 1366–2.

Fire dampers are designed for the installations listed and described in their Handbook.

All fire dampers are supplied with a manual or an actuator-operated mechanism. An optional supply and communication unit is also available. The activation mechanisms are removable and the actuator-operated mechanism can be interchanged with the manually operated mechanism.

The fire dampers have casings made from galvanized sheet metal. The blades are made from non-asbestos insulants and have a rubber seal for cold smoke and an intumescent seal. Intumescent seal expands in fire situation.
