FAQs
What size ducting does this grille fit?
This Manrose Gravity Grille is designed to fit 150mm diameter ducting.
Can this grille be used for both intake and exhaust?
It is primarily designed for exhaust systems (like extractor fans and cooker hoods) to prevent backdrafts. While it has flaps that close, it's not intended for controlled passive air intake.
How do I clean the Manrose 1202W grille?
You can clean it by gently wiping the exterior and flaps with a damp cloth. Ensure the flaps are dry and move freely afterward. Avoid using harsh chemicals or abrasive materials.
What is the main benefit of a gravity grille?
The main benefit is preventing unwanted backflow of air, such as cold drafts, odors, or pests, from entering your ventilation system when the fan is not operational.
Do I need to purchase screws for installation?
Screws for mounting the grille are typically not included and should be sourced separately based on your mounting surface.
Can this grille be installed on a ceiling?
Yes, the grille can be mounted on either walls or ceilings, providing flexibility in installation depending on your ventilation setup.
What material is the grille made of?
The grille is constructed from high-quality materials designed for durability in ventilation applications.
Troubleshooting
Grille flaps are stiff or do not open/close properly.
Check for obstructions like dust or debris around the flap mechanism. Gently clean the flaps and hinge points with a damp cloth and ensure they move freely.
Air leaks around the grille installation.
Ensure the grille is securely fastened to the ducting or mounting surface. Use appropriate sealing tape or sealant around the edges if necessary, ensuring not to impede flap movement.
Noticeable noise or rattling from the grille.
Verify the grille is securely installed and not loose. Minor rattling might occur with strong air pressure; ensure flaps are clean and moving freely. For persistent noise, check ductwork for kinks or obstructions.
Backdraft persists even with the fan running.
Confirm the fan is operating at sufficient speed to open the gravity flaps. Check for any blockages within the ducting or at the external vent outlet.
