FAQs
Can this grill be used for intake ventilation?
This model is designed specifically for air extraction; gravity shutters work best when pushed open by outward airflow.
Does it come with mounting screws?
Fixing screws are generally not included as the required type depends on the surface (e.g., brick vs. wood).
What is the material of the grill?
The Devola Gravity Grill is made from durable plastic, selected for its weather-resistant properties.
Can I paint the grill to match a different wall color?
Yes, standard plastic-safe spray paints can be used, but ensure you do not paint over the shutter hinges.
Is this compatible with 4-inch ducting?
Yes, 100mm is equivalent to the standard 4-inch ducting size commonly used in the UK.
Troubleshooting
Shutters rattling in the wind
This is common in exposed areas. Ensure the unit is installed perfectly level, as tilting can make the shutters more prone to noise.
Shutters stay stuck open
Check for obstructions like dust or cobwebs around the hinge points and clean them with a soft brush.
Pros and Cons
Pros

Cons
- Shutters may rattle in high wind conditions

Setup, Compatibility & Care
Installation is straightforward due to the standard 100mm rear spigot, which is compatible with most flexible and rigid PVC ducting. Simply apply a bead of sealant to the frame edge before fixing to the wall for a weather-tight finish.
For care, periodically inspect the shutter hinges to ensure no dust or grease buildup is hindering their movement. A quick wipe with a damp cloth is usually sufficient to keep the mechanism functional and the exterior looking clean.
