Securit Circular Louvred Vent 165mm - White Round Air Vent Cover

The Securit Circular Louvred Vent 165mm in White is a round ventilation cover designed to let air move freely through a wall, door, soffit or duct opening while keeping wind driven rain and larger debris out. Its angled louvre slats sit at roughly 30 to 45 degrees, so air passes through in both directions while rain is shed away from the opening rather than blown straight in. With a full 165mm diameter and a clean white finish, this circular vent suits soffits, small wall openings and anywhere a round profile gives a neater look than a rectangular cover.

Key Features

• 165mm circular, round profile that fits neatly into a matching round opening
• White colour finish, ideal for matching light fascias, soffits and white UPVC trims
• Angled louvre slats allow two way airflow while shedding wind driven rain
• Discreet, low profile design that blends into soffits and small openings
• Generous free air space for its compact size, helping with everyday ventilation needs
• Durable, weather resistant material built to withstand ongoing outdoor exposure

How to Use / How to Fit

If you are replacing an existing round vent cover, unscrew or unclip the old vent from its sleeve or fixing holes, then fit this Securit louvre vent using the same holes so it lines up with the existing opening. For a brand new installation, core drill or cut a round hole sized to suit the vent, bed and fix the vent in place, and finish the joint around the edge to match the surrounding wall, soffit or door surface. On external walls and soffits, check the louvre slats are angled downward and outward so they continue to shed rain effectively once fitted.

Frequently Asked Questions

What is a louvre vent?
A louvre vent is a ventilation cover made up of angled slats fitted into a wall, door or duct opening. The slats let air pass through while blocking rain and larger debris from entering.

How do louvre vents work?
The slats are set at an angle so air can flow through the gaps in both directions, while wind driven rain and larger debris are deflected away rather than passing straight through.

Where are circular vents used?
Circular vents like this one are commonly used on soffits, small wall openings and anywhere a round hole is easier to form than a rectangular cutout, giving a neat, discreet finish.

How do you fit a louvre vent?
For a straight swap, remove the old cover and fit the new vent using the same fixing holes. For a new opening, core drill a round hole to size, fix the vent in place and finish the joint to match the surrounding surface.
