Cotswold Stone Wall Vent Cover Back Draught Air Gravity Shutter Ventilation Grille 125mm 5"

Check before ordering. If you are replacing an existing vent, remove it and check the hole size.

Generally, toilet extractor fans are 100mm, but kitchens use 100mm, 125mm, or 150mm, depending on the size.

For utility rooms and laundry areas, a 125mm vent cover is often ideal due to the slightly larger extractor fans and tumble dryers commonly used in these spaces.

By verifying the hole size and considering the typical applications in various rooms, you can ensure that the 125mm (5") Wall Vent Cover is the appropriate choice for your ventilation needs.

Kitchens: Near the cooker hood or on an external wall.

Bathrooms and Toilets: High on the wall or ceiling, opposite the shower or bath.

Utility Rooms and Laundry Areas: Near tumble dryers and high on the wall.

General Tips: Avoid obstructions, place close to the source of moisture or odour, and install on an external wall for direct air extraction.

First, gather your tools: drill, screws, wall plugs, screwdriver, sealant, measuring tape, pencil, and level.

Measure and mark the location for the vent on the wall, then drill a pilot hole at the centre. Cut the hole from the inside wall using a core drill, making it approximately 135mm to 140mm in diameter.

Insert the ducting through the hole, sealing around it with exterior-grade sealant. Position the vent cover over the ducting on the outside wall, mark and drill holes for the screws, insert wall plugs, and secure the vent cover with screws.

Finally, apply sealant around the edges of the vent cover to ensure it's weatherproof.

To maintain a wall vent cover gravity shutter, start by regularly cleaning it to ensure efficient operation. Remove the vent cover, if possible, and wash it with warm, soapy water to eliminate dust, dirt, and debris. Use a soft brush to clean the shutter blades gently.

Rinse thoroughly and allow it to dry completely before reattaching. Additionally, check the vent for any obstructions or blockages, both inside and outside. Inspect the shutter mechanism to ensure it moves freely and isn't hindered by dirt or damage. Lubricate any moving parts with a silicone spray if necessary.

Periodically inspect the sealant around the vent cover to ensure it remains intact and reapply if needed to maintain a weatherproof seal. Regular maintenance helps keep your gravity shutter functioning optimally, promoting good airflow and prolonging its lifespan.

The primary differences between a 100mm, 125mm, and 150mm wall vent cover are their circular connection size and the applications they are best suited for. 

100mm (4") Wall Vent Cover: This size is typically used for smaller ventilation needs, such as in toilets and small bathrooms. It is designed to fit 100mm ducting and is ideal for smaller extractor fans and ventilation systems.

125mm (5") Wall Vent Cover: Slightly larger, this size is suitable for medium-sized ventilation needs, including kitchens, utility rooms, and larger bathrooms. It fits 125mm ducting and is often used with medium-sized extractor fans, cooker hoods, and tumble dryers.

150mm (6") Wall Vent Cover: The largest of the three, this size is used for high-capacity ventilation needs. It is ideal for large kitchens, commercial spaces, and areas requiring significant airflow. It fits 150mm ducting and supports large extractor fans and heavy-duty ventilation systems.

Fixing screws or plugs are not included because different wall surfaces require specific types for proper and secure installation.

The wall vent shutter is designed to resist fading and degradation from sunlight, maintaining its colour and durability even after prolonged UV exposure.

The shutter vent is made from engineered polymers like polycarbonate, modified ABS and specially formulated PVC, enhanced with additives to improve temperature resistance, UV stability, and antistatic properties.
