Description
Soler & Palau CAR100 4 In Steel Backdraft Damper
The Soler & Palau CAR100 is a 4-inch steel backdraft damper engineered to prevent unwanted reverse airflow in residential and light commercial ventilation systems. Designed for use with exhaust fans, range hoods, bathroom fans, and other ducted ventilation equipment, this damper automatically opens when air is flowing in the correct direction and closes tightly when airflow stops — keeping conditioned air in and outdoor air, pests, and drafts out.
Built with a durable steel construction, the CAR100 delivers long-lasting performance in demanding environments. Its gravity-operated design requires no external power source, making installation straightforward and maintenance minimal.
