Chimney extraction wind turbine 120mm

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.

• 120mm diameter compatibility: ideal for standard 120mm ducts.

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

• Durable construction: galvanized steel for corrosion resistance and long outdoor life.

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