The Vent Adjustable Ventilator 229mm x 76mm is an efficient and versatile solution for airflow management. It features a circular louvre grille with spring clips that clamps securely into tubes and holes ranging from 100mm to 150mm in diameter, making installation quick and hassle-free. Designed for both internal and external use, this ventilator boasts inverted fixed open louvres that allow for optimal airflow while maintaining a flush finish. The included removable flyscreen adds protection against insects and debris, enhancing usability. Made from U.

V.-stabilized plastic, the ventilator resists the effects of sunlight, ensuring long-lasting performance. This ventilator is not suitable for combustion air supply, as louvres with flyscreens must not supply air for boilers, stoves, or fires. Additionally, it is not recommended for external walls of buildings over 11m where people sleep or within 1m of the boundary for shorter buildings, as per regulations in England.
