AHE

    Self adjustable extract valve with humidity sensor and Boost function

    • Normal/Max airflow

    • Boost function activated by 230V

    • Humidity sensor

    • Nominal air flow at 80 Pa

    • Vertical and horizontal installation

    Operation

    The valve continuously adjusts its airflow between the Normal and Maximum settings according to the humidity level in the extract air. Maximum airflow can be activated via the boost function by applying a 230 V power supply. They are ideally suited for central exhaust ventilation systems.

    Easy installation

    The valve features an internal construction suitable for both vertical and horizontal installation.

    AHE is a residential extract valve designed for central exhaust ventilation systems. The valve continuously adjusts its airflow between the Normal and Maximum settings according to the humidity level in the extract air. Maximum airflow can be activated via the boost function by applying a 230 V power supply. The Nominal airflow rate is achieved at approximately 80 Pa. The actual airflow depends on the static pressure in the duct system and humidity level. Typical applications include bathrooms, kitchens, and other rooms with fluctuating humidity levels in residential buildings, hotels, and office premises

    Highlights

    • Normal/Max airflow

    • Boost function activated by 230V

    • Humidity sensor

    • Nominal air flow at 80 Pa

    • Vertical and horizontal installation

    Installation

    AHE is suitable for vertical or horizontal installation and is designed for connection to a Ø125 mm circular duct.

    Design

    AHE valve is manufactured from white polystyrene. Circular connection is equipped with a rubber gasket to ensure an airtight connection.

    Operation

    A humidity level below 30% RH provides standard ventilation at the Normal airflow rate. The valve continuously adjusts its airflow between the Normal and Maximum settings according to the humidity level of the extract air. The Maximum airflow rate is achieved at 60% RH. The Boost function for Maximum airflow is activated by applying a 230 V power supply. When the power supply is interrupted, the valve automatically returns to operation based on humidity level.
