125mm Stainless Steel Ventilation Cowl With Non Return Flap For Round Ducting

125mm Stainless Steel Ventilation Cowl with Non Return Flap for Round Ducting

Designed for external wall ventilation applications, the 125mm Stainless Steel Ventilation Cowl with Non Return Flap helps protect against wind and back pressure while maintaining efficient exhaust airflow.

Manufactured from stainless steel, the cowl offers durability and corrosion resistance for long-lasting performance in exposed environments. The integrated non-return flap opens during operation to allow exhaust air to disperse externally and closes when not in use to help prevent backdraft airflow returning through the duct.

Designed for exhaust air applications only, the cowl also helps shield the duct outlet from wind exposure by deflecting airflow away from the external wall.

Suitable for use with 125mm round ducting, it provides a reliable solution for domestic and commercial ventilation systems and operates in temperatures ranging from -15°C to +60°C.
