External Air Vent Hooded Cover with Gravity Flap 100mm

This hooded external air vent cover is designed to finish off a wall or duct outlet neatly while helping to manage airflow in domestic and light commercial ventilation. It supports consistent air movement while offering added protection from the weather and airborne debris.

Made from durable ABS plastic, it’s built for reliable use indoors or outdoors. The hooded louvre face helps deflect rain and leaves, while the built-in gravity flap acts as a simple backdraught damper, closing when airflow stops to help reduce unwanted draughts.

Ideal for use with ventilation ducting where you want a tidy external termination point, such as utility rooms, bathrooms, kitchens, garages and general HVAC runs. The round spigot format is intended to connect to compatible round ducting for a straightforward fit.

A practical choice for upgrading tired or broken vents, or for new installations where a cleaner finish and basic backflow protection are needed. The white finish suits most exterior walls and internal service areas without drawing attention.
