Product Information
Full details
The Airvent 150mm Fixed Louvre Grille is a versatile ventilation solution ideal for both residential and commercial property owners looking to facilitate consistent airflow in bathrooms, kitchens, or utility rooms. Its primary benefit is the combination of efficient, non-mechanical air circulation and a durable construction that fits seamlessly into existing ducting systems; however, users should note that as a fixed-louvre design, it does not feature an integrated damper to manually block or restrict airflow once installed.

FAQs
Can I paint this grille a different color?
Yes, it can be painted with a high-quality, weather-resistant exterior spray paint designed for plastic, provided the surface is cleaned and primed first.
Is this grille suitable for use with a bathroom extractor fan?
Yes, it is highly compatible with 150mm extractor fans and provides excellent passive exhaust for moist air.
Does this grille include a fly screen?
This model is a standard fixed louvre grille and does not typically include an internal insect mesh.
Can I install this on a ceiling?
While intended for walls, it can be mounted to ceiling ducts, though it lacks the gravity-closing flaps often preferred in those applications.
What tools are needed for installation?
You will need a drill, wall plugs, matching screws, a screwdriver, and a tube of exterior-grade silicone sealant.
Troubleshooting
Airflow seems restricted
Check the rear of the grille for debris or buildup and ensure the internal ducting is not crushed or blocked.
Water leaking behind the grille
Re-apply silicone sealant around the perimeter of the faceplate to bridge any gaps between the grille and the wall surface.
Grille rattles during high wind
Check that all mounting screws are tightened fully. If the rattling persists, apply a small foam gasket behind the frame to dampen vibrations.
Pros and Cons
Pros
- Simple, non-mechanical design ensures long-term reliability
- Provides a protective barrier against rain and external debris
- Easy to clean and maintain without removing the entire unit
- Aesthetically neutral brown finish fits diverse architectural styles
Cons
- Fixed louvres mean airflow cannot be adjusted or closed manually
- Requires proper sealing to ensure no moisture leaks behind the frame
- Not suitable for high-pressure exhaust systems that require backdraft shutters
Setup, Compatibility & Care
Installation should be performed by securing the grille housing directly to the external wall surface using appropriate screws and wall plugs. Ensure the circular spigot fits snugly into your 150mm ducting; it is recommended to use a small amount of silicone sealant around the edges where the frame meets the wall to prevent water ingress.
For ongoing care, the grille should be inspected seasonally. Dust and spiderwebs can accumulate on the fixed louvres over time, reducing airflow efficiency. Use a soft brush or a damp cloth to wipe the slats clean annually, or more frequently if installed in high-pollen or coastal environments.
