Extended Product Information
FAQs
Does this grille include a fly screen?
This model is designed as a gravity shutter and typically does not include a mesh fly screen to ensure maximum airflow.
Can I use this for an intake vent?
While it is designed primarily for extraction, it can be used for intake, though airflow may be slightly restricted by the weight of the shutters.
Is the white finish paintable?
Yes, the material can be painted to match your exterior wall color, though it is recommended to use a plastic-adhesion primer first.
What tools are needed for installation?
You will generally need a drill, screws, appropriate wall plugs, and a sealant (like silicone) to waterproof the perimeter of the grille.
Is this suitable for tumble dryer venting?
It is not recommended for tumble dryers as lint buildup will quickly clog the shutter mechanism.
Troubleshooting
Louvers are stuck in the open position.
Check for debris or dust accumulation around the shutter hinges and clean with a damp cloth.
Louvers rattle when it is windy outside.
Verify that the grille is mounted perfectly level. If the rattling persists, it may be due to extreme wind pressure which can sometimes be mitigated by adding a small piece of weather stripping to the shutter seat.
Airflow seems restricted.
Ensure the 100mm ducting connected to the back of the unit is not crushed, bent, or obstructed by insulation inside the wall cavity.
Pros and Cons
Pros
- Prevents cold air backdrafts effectively
- Easy to install on standard ducting
- Clean, unobtrusive white finish
- Durable and weather-resistant material
- Suitable for both residential and commercial use
Cons
- Louvers may rattle in very high-wind environments
- Not suitable for use with high-pressure industrial fans
- Fixed 100mm size limits use with larger duct systems
Setup, Compatibility & Care
Installation requires a 100mm hole cut through the exterior wall. Ensure the ducting is securely fastened to the back of the grille using appropriate duct tape or a jubilee clip to prevent air leakage. When mounting, ensure the grille is positioned so that the louvers hang vertically; if the unit is installed at an angle, the gravity shutters will not close properly.
To maintain optimal performance, periodically inspect the grille for dust, lint, or debris buildup that might obstruct the movement of the shutters. Clean the grille with a damp cloth and mild soap during seasonal exterior maintenance to ensure the louvers continue to operate freely.
