The THERMSHIELD FD series of 'EIS' classified singleblade 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 fulfills 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.
THERMSHIELD FD Fire dampers consist of steel sheet case, calcium silicate damper blade, damper blade mechanism outside of the airflow and a manual or electric actuator.
The THERMSHIELD FD case is made out of galvanized steel sheet and the calcium silicate blade is equipped with brass bearings and seals made out of polyurethane and elastomer rubber.
THERMSHIELD FD casing is manufactured from galvanized steel sheet, but on demand can be produced out of:
Fire damper for areas with potentially explosive atmospheres are also available.
Fire Damper classifications and performance data are available in the THERMSHIELD FD Declaration of Performance available on our website.
Factory production control which includes a continuous program of cyclic and leakage testing of production dampers to ensure full compliance of every product.
THERMSHIELD FD dampers can be used where the operating total system pressure is up to 1000 Pascals and duct velocities to 12 m/second.
Suitable for:
The ThermShield FD damper blade is normally open and Fail-safe to the closed position.
Actionair ThermShield FD dampers are designed for applications in normal dry filtered air systems.
