Design

The THERMSHIELD FD series of 'EIS' classified single blade mechanical or automatic fire dampers, marked with a CE, are designed to prevent the spread of fire and smoke while maintaining compartmentation in internal normal dry filtered air systems. The THERMSHIELD FD fire damper is constructed with a steel sheet case and a calcium silicate damper blade, operated by a mechanism located outside of the airflow. It can be activated manually or through an electric actuator.

The damper comes in various sizes to accommodate different circular ductwork and can be installed using different methods to suit various supporting constructions. The case is made of galvanized steel sheet, and the calcium silicate blade is equipped with brass bearings and seals made of polyurethane and elastomer rubber.

THERMSHIELD FD has been classified as meeting the EIS standards for integrity, low smoke leakage, and insulation, making it suitable for demanding projects. It also fulfils the requirements of EN 15650, has been fire tested to EN 1366-2, and classified to EN 13501-3.

The THERMSHIELD FD damper blade is designed to remain normally open and has a fail-safe feature that automatically closes at 72 degrees Celsius to maintain compartmentation.
