Chimney extraction wind turbine 315mm

Passive, wind-powered turbine mounted on chimneys or exhaust ducts to boost natural draft, prevent backdrafts, and shield the duct from leaves, dirt, and precipitation. No electricity required. Made from durable galvanized steel for outdoor use.

Key features

• Fully passive operation: wind turns the turbine to enhance exhaust flow without any power source.

• 315mm diameter compatibility: ideal for standard 315mm ducts.

• Backdraft protection: helps prevent reverse airflow and drafts from pulling air back into the building.

• External protection: shields the duct opening from leaves, dirt, water, and precipitation.

• Low maintenance: simple mechanical design with minimal moving parts.
