Compliance and Performance by Alpine Ventilation
The requirements for residential ventilation have fundamentally shifted. New NCC 2022 Condensation Management provisions require changes both to exhaust fans and the way they are vented. Achieving minimum flow rates and also guarantee continued ventilation in non-naturally ventilated rooms is required to satisfy NCC Clause 10.8.2. The all-new Header Box Fan by Alpine Ventilation with a built-in run on timer is designed specifically to satisfy and exceed new NCC provisions under 10.8.2.

Optimised Performance & Compliance Certainty
This header box exhaust fan is designed to be the definitive answer to common installation challenges, while delivering superior performance over standard axial fans, especially over long duct runs. The integrated adjustable run-on timer is crucial for ensuring continuous ventilation post-use of rooms not naturally ventilated. This helps to manage residual moisture levels, reducing risk from long term exposure to moisture.
Powering this fan is an AC motor with durable Japanese bearings, these robust components deliver an industry first 104 L/S, 375 m³/h max airflow rate. This sustained high static pressure capability ensures specified ventilation rates are maintained throughout the duct system during operation. A high airflow rate is critical when considering that fans now need to be ducted externally and cannot simply exhaust air into the roof cavity.
The housing enclosure of the header box fan ensures noise and vibration transmission to surrounding spaces are reduced dramatically, allowing this fan to achieve a volume of 38 dB at 3 meters.
Built With Installers and Aesthetics In Mind
Getting the job done fast and done right is critical on every site. That is why this header box fan comes pre-wired with a DIY lead and plug, so you can speed -up the connection process without cutting corners. The low-profile (210mm) housing enclosure fits easily within typical ceiling cavities, saving you a headache in tight spots. The contemporary, minimalist design ensures the finished installation aligns with modern aesthetics and is easy to clean.

By specifying the Alpine 250 series header box fan, architects, engineers and builders gain a reliable, compliant exhaust solution that complies with certification and delivered guaranteed moisture control and acoustic performance. The Header Box Exhaust Fan range by Alpine Ventilation is the smart builder’s choice.
