Kair louvred wall vent grille 100mm

A black plastic wall vent grille helps move air while keeping insects out, which is exactly what you want where moisture and airflow meet. The Kair 100mm louvred wall vent grille includes fixed louvres and an anti insect flyscreen, so it can suit extractor fan venting, kitchen and bathroom airflow, and grow space ventilation without adding extra complexity. Easy push fit installation means you can connect ducting and fittings together with minimal fuss, making it a practical swap or upgrade when you want a neat outlet that stays serviceable.

The essentials

This Kair vent grille is built as a ducting air outlet or inlet option with fixed louvres, plus an anti insect mesh flyscreen. The louvres are designed to control airflow direction, and the flyscreen helps reduce the chance of insects entering the ducting run. According to the product details, the grille sits at an overall external size of 155mm x 155mm, which helps it fit typical wall and duct cut outs when you are working with compatible Kair 100mm round systems.

A key practical point is the rear spigot connection. The grille comes with a 4 inch or 100mm round male rear spigot, and the information provided notes that you can cut the spigot off if you prefer a flat surface for mounting. That flexibility can make installation easier where the wall surface or duct layout benefits from a flatter seating area.

You can also flick the louvre open using a flat head screwdriver to make cleaning the insect screen easier, which is useful for day to day maintenance. This is the sort of detail that matters if the grille will be used in busy kitchen environments or in bathrooms where airflow is needed but cleaning should stay straightforward. It is a simple item, but it is clearly designed for real-world service and access.

What stands out

The standout feature here is the combination of fixed louvres and an anti insect flyscreen in one grille, giving you airflow control with a barrier against insects. That makes it a sensible choice when you are running ducted extraction, because you want the fan to do its job while the vent stays protected when the system is not actively moving air.

For compatibility, the grille is described as fitting inside specific Kair 100mm round female duct pipe parts, including DUCVKC250, and also being suitable with a 102mm flexible hose part listed as DUCP0092/102/35. It is also described as easy to install by pushing the duct and fittings together, which helps reduce the time spent fitting and adjusting. 😊

If you are working with a bathroom or kitchen extractor fan vent, this grille can act as the external outlet section that ties into the ducting run. It is also listed as suitable for hydroponics fan ventilation and for an in line extract fan setup, so it can cover more than one practical scenario around airflow management. Keep in mind that the louvred design is fixed, so the airflow control is via the louvres rather than an adjustable shutter mechanism.

Who it’s for

It’s a good fit if you need a neat black wall vent grille that includes an anti insect mesh flyscreen, especially for ducted bathroom or kitchen extractor fan installations. It also makes sense if you are building or maintaining hydroponics ventilation where you want airflow without insects making their way through the vent. You’ll like it if your setup uses Kair 100mm round ducting parts such as the compatible rear or female duct options mentioned in the product details.

You may want to skip it if your installation does not match the stated duct sizing and connection approach, since it relies on the 100mm round spigot style interface. Not every layout will benefit from the option to cut off the rear spigot, so check how your wall and ducting meet before fitting. Overall, it’s a straightforward, serviceable vent grille that prioritises practical airflow and maintenance access over complicated features. 🛠️
