Soler & Palau CAR100 4-Inch Steel Backdraft Damper

The Soler & Palau CAR100 is a 4-inch steel backdraft damper designed to prevent air backflow in ventilation systems. This gravity-operated damper automatically closes when the exhaust fan is turned off, blocking outside air, pests, and debris from entering through the ductwork.

Key Features:

• 4-inch diameter steel construction for durability and long service life
• Gravity-operated blades that open during fan operation and close when fan stops
• Prevents backdrafts, cold air infiltration, and pest entry
• Suitable for residential and light commercial exhaust applications
• Compatible with standard 4-inch round ductwork
• Easy installation between duct sections or at wall/roof terminations

Ideal for use with bathroom exhaust fans, kitchen ventilation, dryer vents, and other applications requiring backdraft prevention. The steel construction ensures reliable operation in various environmental conditions.
