Airvent Fixed Louvre Grille - 150mm - Brown

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.

Yes, it is highly compatible with 150mm extractor fans and provides excellent passive exhaust for moist air.

This model is a standard fixed louvre grille and does not typically include an internal insect mesh.

While intended for walls, it can be mounted to ceiling ducts, though it lacks the gravity-closing flaps often preferred in those applications.

You will need a drill, wall plugs, matching screws, a screwdriver, and a tube of exterior-grade silicone sealant.

Check the rear of the grille for debris or buildup and ensure the internal ducting is not crushed or blocked.

Re-apply silicone sealant around the perimeter of the faceplate to bridge any gaps between the grille and the wall surface.

Check that all mounting screws are tightened fully. If the rattling persists, apply a small foam gasket behind the frame to dampen vibrations.
