FDMS-VAVFire damper

FDMS-VAV – The damper in the HVAC equipment duct that prevents the spread of fire and combustion products from one fire segment to another by shutting off the airflow at the fixture points. In this case we are adding to the damper a function of controlling of the airflow rate - same like a variable airflow regulator. The damper is fitted with collar, that replaces the function of the fire seals and simplifying its own installation in fire separating constructions. In this case the fire damper casing is extended by an extension, which includes the measurement cross and the controller.
