Product Details

Iron vent vs plastic vent: galvanized iron is stronger and more heat resistant than plastic, so it keeps its shape and finish near hot cooker hoods and in humid bathrooms, while a one-way flap keeps smells from neighboring rooms out of your space.

Low-maintenance design: the flap is self-cleaning during normal airflow, and the smooth galvanized surface wipes clean easily. Periodic removal of dust on the flap keeps the seal tight for years of reliable one-way ventilation.

Product Data

This round iron vent is built for exhaust systems that need one-way airflow. The galvanized steel body resists rust in humid kitchens and bathrooms, and the gravity flap inside closes the moment airflow stops, keeping smoke, odors and cold drafts from coming back through the duct. Sizes range from 100mm to 400mm (about 4 to 16 inch) to match standard exhaust pipes.
