Design

ThermShield FD, square/rectangular CE Marked ’EIS’ Rated Fire Damper. ThermShield FD consists of steel sheet case, calcium silicate damper blade, damper blade mechanism outside of the airflow and an actuating mechanism. Dampers are tested according to the EN 1751 for airtightness and retain class 2 leakage on the closed damper blade and class C on the casing air leakage. The ThermShield FD case is made out of galvanized steel sheet, Calcium silicate blade is equipped with brass bearings and seals made out of polyurethane and elastomer. Damper tested according to EN 1366-2 “Fire resistance tests for service installations- Part 2: Fire dampers”. Classification of the fire dampers is defined according to EN 13501-3 Fire classification of construction products and building elements. The damper shall be installed as per the installation instructions, with the detailed performance for each installation method according to Declaration of Performance.

For automatic operation

ThermShield FD, square/rectangular CE Marked ‘EIS Rated’ Fire Dampers with their appropriate actuators shall have spring Fail-Safe Closed operation only, with selected actuators, as fitted at point of manufacture.

For manual operation

ThermShield FD, square/rectangular CE Marked ‘EIS Rated’ Fire Dampers with Manual spring return mechanism and thermal fuse, triggered automatically when the temperature inside the duct reaches 72 °C.
