4" 100mm Wall Vent Flapped White

When extracting from your bathroom, utility room, toilet shower or kitchen that is in an exposed area then fitting a wall flap vent shutter is essential. Three lightweight horizontally mounted flaps within the grill allow stale moist air to be extracted when your ventilation system is switched on. When not in use or when your extractor fan is switched off, the flaps gently fall closed to prevent wind, rain and drafts pushing back into your home.

The shutter vent can be mounted to your external wall and will fit into a 100mm 4" dia hole, ventilation ducting or wall sleeve.

The plastic shutter is suitable for internal and external mounting.
100mm (4") diameter that fit standard ducting or wall sleeves.
Lightweight blades for reduced airflow restriction.
Easy screw fixing and connection to ducting.
The plastic shutter blades are easily removed for fitting & cleaning.
