This 4-inch extractor fan grille offers a complete wall termination solution that combines ventilation functionality with effective insect protection. Designed for use with 100mm extractor fans, it provides a neat, professional finish to wall openings while incorporating an integral fly screen that prevents insects, mosquitoes, and other small pests from entering through the ventilation system. The louvred design allows for efficient airflow while maintaining a discreet appearance that complements both interior and exterior walls.
Practicality is at the forefront of this grille's design, featuring a removable front section that provides easy access for cleaning and maintaining the fly screen. This thoughtful detail ensures the screen can be kept free from dust and debris, maintaining optimal airflow and hygiene over time. Compatible with both rigid and flexible 100mm round ducting, this grille serves as a versatile finishing component for bathroom extractor fans, kitchen ventilation, utility rooms, and any other application where ducting terminates through an internal or external wall.
Integrated Fly Screen: Built-in mesh screen prevents insects, mosquitoes, and small pests from entering via the ventilation duct.
Removable Front Grille: Allows quick and easy access for cleaning the fly screen without dismantling the entire installation.
Louvred Design: Directs airflow efficiently while providing a clean, finished appearance.

1. How does this differ from a gravity shutter?
Unlike a gravity shutter which has moving louvres that open and close, this grille features fixed louvres with an integrated fly screen. It provides insect protection but does not seal against backdraughts or rain.
2. Can this be used on an external wall?
Yes, it can be used on external walls, but unlike a gravity shutter, it does not provide a seal against rain penetration or backdraughts. For weather-sealed applications, a gravity shutter would be more suitable.
3. How do I clean the fly screen?
The front grille is removable, allowing you to easily access the fly screen for cleaning. Simply detach the front cover to brush or wipe away accumulated dust and debris.
4. Will this fit my existing 100mm ducting?
Yes, the grille is designed to connect to standard 100mm round rigid or flexible ducting, making it compatible with most 4-inch ventilation systems.
5. Is the fly screen fine enough to block small insects like midges?
The integral fly screen is designed to block common insects such as flies, mosquitoes, and wasps. It provides effective protection against most small pests that might otherwise enter through ventilation openings.
