    AERECO EXR 309 - Hygrosterotrolled with acoustic attenuation + acoustic hood

    Vent - Hygrosterotrolled with acoustic attenuation + acoustic hood

    EXR hygrost controlled diffusers are controlled automatically. The air flow rate depends on the water vapour content (relative humidity) inside the room. The control sensor is a polyamide tape which, under the influence of changes in relative humidity in the air, changes its length, which causes a bigger or smaller opening of the throttle and thus bringing more or less airflow to the room.
    Hygrosterised air vents operate in the range from 35 to 70% of relative humidity. If the humidity in the room is lower or equal to 35%, the air inlet is closed and a minimum air stream is supplied to the room. As the humidity increases, the air inlet opens and at 70% or more of the relative humidity the maximum efficiency is achieved.
    Hygrost controlled ventilators are designed in such a way that the outside air does not come into direct contact with the sensor. This allows the conditions indoors, not outdoors, to be analysed.
    A hygrocontrolled air inlet operates without human intervention and does not require electricity.

    Manual closing and full opening function of the EXR diffuser: When the lock is set to the open position, the damper changes its position according to the relative humidity in the room. The air flow rate is between 7 and 28 m³/h. When the damper is in the closed position (flap up), the damper is set to the minimum flow rate, the diffuser delivers up to 7 m³/h at 10 Pa.

    Slanted direction of airflow: Optimal positioning of the air outlet duct in the housing provides increased comfort for residents.

    Acoustic connector and acoustic hood: The EXR diffuser comes complete with a connector and acoustic hood to provide high insulation values Dn,e,w = 42 dB.
