Steel Back Draft Inline Dam250mm

Steel Back Draft Inline Damper 250mm

This spring-loaded backdraft damper is designed to automatically prevent reverse airflow in round duct ventilation systems. Made from durable steel, the damper blade opens only when air flows in the correct direction and immediately closes when airflow stops, thanks to a built-in spring mechanism. It’s ideal for HVAC supply and exhaust systems, bathroom fans, kitchen hoods, or any application where air backflow must be prevented.

Features:

• All-steel construction for durability and corrosion resistance

• Spring-loaded mechanism ensures fast and reliable closure

• One-way airflow control to prevent backdraft, dust, and insects

• Ideal for use in ventilation, exhaust, and air supply applications
