Airflow Aventa Shower Fan Kits 4 Inch / 100mm
The Airflow Aventa In-Line Showerlite Fan Kit is designed to provide powerful yet quiet remote extraction for bathrooms, shower rooms and en-suites where longer duct runs are required. Its compact 100mm mixed-flow fan offers two-speed performance of 145 or 187m³/h, combining the airflow and pressure required for ducted installations with convenient remote mounting in a loft, cupboard or service space. An adjustable 2–30 minute overrun timer allows ventilation to continue after the room has been used, helping remove lingering moisture and humid air. The kit also incorporates a 4W cool white LED shower light delivering 220 lumens, combining illumination and extraction at the ceiling point for a clean, discreet finish. Supplied as a comprehensive kit with 6m flexible ducting and installation accessories, the Aventa Showerlite provides a convenient all-in-one solution for professional bathroom ventilation installations.
