CFDM / CFDM-V – 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 CFDM-V design is this damper in version with extended body damper, when occurs dish valve assembly directly into the dampers body and therefore this combined product can be used as terminal element with fire resistance when incorporated into the fire separating construction.
