SOLER & PALAU CAR150 6" Steel Backdraft Damper

The SOLER & PALAU CAR150 6" Steel Backdraft Damper is an airflow control component used to prevent reverse air movement through ductwork when ventilation equipment is not operating in HVAC systems. Installed within round duct applications, the damper opens during active airflow and closes automatically when airflow stops, assisting in maintaining directional ventilation. It is commonly used in exhaust and intake systems for commercial and residential HVAC installations, including inline fan and wall vent assemblies. The steel construction supports stable operation in continuous air circulation conditions, while the damper assembly assists in controlling unwanted outside air entry within the ventilation system.
