Featuring an integrated non-return backdraft damper and supplied with screws and cowl-to-wall rubber gasket, this stylish steel wall extractor hood vent outlet has an unobtrusive profile.
A cushioned low noise flap prevents unwanted sounds from being heard from within the property.
This also features a gravity flap to prevent small mammals and birds from accessing the ducting attached to it.
The gravity flap is stylishly covered by the square shape cowl and in doing so, offers more of an aesthetic appearance than most traditional plastic grilles.
Stainless steel Cowles offer greater weatherproofing, and are not affected by ultraviolet rays like some plastics can be.
The grille can be cleaned using any stainless steel cleaner.
Ideal for all tumble dryer vent pipes / hoses, bathroom vents & extractors, air conditioning units, kitchen fans & vents, home wall vents, heat transfer & ventilation systems, gas & electric dryers, cooker hood extractors, as well as a wide variety of industrial uses.

Is the non-return flap in this item (model DUCSS103) spring loaded or does it rattle in windy weather?
Thank you for your question
The Damper flap is attached by a wire hinge and is designed to close with the aid of gravity this means it is only suitable for wall mounted applications.
Would this be suitable to provide air flow for a gas fire or does the flap require a fan to push the flap open?
Thank you for your question. This item does require air to open the flap. We recommend a black hole ventilator for gas fires if you know how much free air is required. Here are two options for you.
looking at the reviews - I can see that this is cowl is not flat to the wall but does the hinge shut at 90 degrees
Is this an inlet vent or outlet? Which direction does the valve allow airflow?
