Designed to contain fire suppression gases within a system.
The DAMPERS are manufactured to fully close under controlled spring operation of pneumatic or electric ACTUATOR.
The DAMPER incorporates silicon blade tip seals rated to 250°C and with the inclusion of stainless steel side seals provides a seal across the DAMPER blades to
BS EN 1751:1999 Class 3. (Tested by
BSRIA)
The DAMPERS can be manufactured with standard external steel linkage or internal steel linkage, which minimises the leakage through the casing due to the fact that only the drive spindle penetrates the damper casing.
