    Intended Use

    The Airsonett AIR-4 is a Mobile Air Cleaner intended to be used to remove particles from the air for medical purposes. The device is intended for home use only.

    Device Description

    Airsonett is based on the Temperature controlled Laminar Airflow (TLA) technology. The air from the room enters the Airsonett and passes a filter that captures allergens and other particles. The filtered air is cooled to slightly below the ambient room temperature and is supplied with a low velocity from the air supply nozzle. Since the filtered air is slightly cooler, and therefore heavier than the surrounding air, the filtered air will descend slowly from the air supply nozzle by means of gravity in a laminar manner (non-turbulent). This descending colder air counteracts the body convection, displaces the allergen load in the breathing zone and thus dramatically reduces the level of inhalant allergens for the patient all through the night.

    Air is drawn in through the air intake at the floor level and through the HEPA filter. A silent Blower (fan) brings airflow through the filter. The air is directed through the Cooler/Heater and divided into a cool respectively warm air flow. The cool air flow is directed through the Air guidance arm (neck) and out through the Airshower (Air Supply Nozzle). The Airshower can be altered in height, by adding/removing and combining the neck parts, to adapt to different types of environments. The warm air flow is directed to the Warm air outlet. On its way to the outlet the air flow passes the electronics and transports away the extra heat produced by the electronics.

    Airsonett is based on a microprocessor controlled supervisory system. This system controls the device behaviour by measuring temperatures, controlling thermoelectric modules and fan unit, monitoring user interaction as well as management of internal timers to keep track of the total ontime for the system and time since last filter change. The control functions (Front Panel Board) and power distribution function (Power Electronics Board) are allocated on two separate circuit boards.
