125mm Ventilation Louvre Grille with Insect Flyscreen – White

Improve and protect your external ventilation system with this 125mm White Ventilation Louvre Grille with Insect Flyscreen, designed for use with System 125 ducting in domestic ventilation applications.

Manufactured from durable high-impact polypropylene, this external wall vent is built for long-lasting performance while helping protect ducting systems from water ingress, insects, and airborne debris. The louvred grille design helps deflect low levels of wind pressure away from the fan to support efficient airflow.

Featuring a 125mm male spigot connection, the grille fits securely inside System 125 ducting for quick and easy installation. The integrated flyscreen mesh helps prevent insects, nesting materials, and debris from entering the duct, reducing the risk of blockages and maintaining cleaner airflow.

With a free airflow area of 6,123mm², this vent grille delivers reliable ventilation performance.
