The brand-new Halton Marine circular fire damper is type-approved class A0(A60) fire damper for use in marine and offshore ventilation systems to prevent the spread of fire inside the ductwork. In the event of temperature rise in a ductwork, fusible link releases and cuts off either voltage to the spring return actuator (in electrical model) or operating pressure to the spring return actuator (pneumatic model), allowing the spring to close the damper blades. In electrical and pneumatic models the fire damper opens automatically, when the fuse has been changed and the voltage to the motor (Halton fire damper type FDO-EL) or pneumatic air supply (Halton fire damper type FDO-PNR) is re-established. Halton fire damper type FDO-SP comes with spring-actuated operation system which requires a manual reset of the fire damper into open position in case the fuse has released.
Lighter, tighter and with more flexibility in dimensions
