Kair Louvred Vent Grille 150mm

A clean, functional wall vent grille helps manage airflow while keeping insects out, and this Kair unit is built for straightforward ducting setups. The 150mm round size suits common extract fan vent runs, kitchens, bathrooms, and similar ventilation applications where you want a tidy finish. It is a white plastic air outlet or inlet grille with fixed louvres and an anti insect flyscreen, with a front cover that sits neatly over the opening. 😊

Using the Kair 150mm louvred wall vent grille, you get a simple push fit approach for connecting ductwork and fittings, and the flyscreen can be accessed as needed for cleaning. The louvres are designed to be flicked open using a flat head screwdriver, which makes routine maintenance practical rather than fiddly. For installations that prefer a flatter rear, the 6 inch, 150mm round male spigot can be cut off if you want a flat surface behind the grille. 👌

The essentials

This white plastic ducting vent grille provides a square front with fixed louvres and an anti insect mesh flyscreen. It is intended to work as an air outlet or inlet as part of a ducted system, so you can keep airflow consistent without leaving the ductwork exposed. With an external dimension of 183mm x 183mm, it is made to suit typical wall penetration sizes for ventilation runs. 🏡

The louvred design helps control airflow direction while the flyscreen reduces the chance of insects entering the ducting. You can flick the louvres open with a flat head screwdriver, which also helps when you need to clean the insect screen. That balance of airflow control and accessible maintenance is useful in places like bathrooms and kitchens where fans are running regularly.

It also has broader compatibility beyond standard domestic ventilation. If you are working with hydroponics airflow or using an in line extract fan setup, the grille can help you route air through ductwork while retaining the anti insect barrier. It is the kind of part that makes upgrades and repairs easier because it is built for duct connections rather than complicated fabrication.

Key features

The grille combines a louvred face with a removable accessible approach to the insect mesh, so cleaning does not have to mean disassembling the whole system. The anti insect flyscreen sits in front of the airflow path, helping reduce insect ingress while still allowing air movement. With fixed louvres you get consistent venting behaviour without relying on moving flap assemblies.

Installation is designed to be practical, using push fit ducting and fittings together. The 150mm size aligns with matching Kair duct parts, including the Kair 150mm round female duct pipe part DUCVKC267 and the 152mm flexible hose part DUCP0092/152/35. If your layout requires a different rear profile, you can cut off the 6 inch, 150mm round rear spigot for a flatter surface.

For many installations, that flexibility matters because wall thickness, duct routing, and fitting choices can vary. Think about how you will route the ductwork first, then choose whether you need the spigot in place or you prefer it cut off for a smoother backing surface. It is a simple component, but it can make the difference between a neat final finish and a vent that still needs tweaking on site.

What you’ll notice day to day

You will likely appreciate how the louvred grille keeps the vent looking tidy while still supporting airflow for extractor fan systems. It is also easier to maintain because the louvres can be opened to allow access for cleaning the insect screen. That helps reduce the build up you can get when insect barriers are present but never properly serviced.

It suits household ventilation jobs where ducting runs need a wall outlet or inlet, particularly bathroom and kitchen extractor fan vent setups. If you are managing airflow in a hydroponics environment or building an in line extract fan arrangement, it can also be used as part of the duct route, provided your ducting dimensions match the 150mm or compatible hose options. It may not suit very compact wall openings where 183mm x 183mm external dimensions leave no clearance, so check your space first before fitting.
