• Material: UV resistant plastic (prevents ageing caused by exposure to sunlight).
• Nominal diameter 100 mm
• Three-phase EC brushless motor of external rotor type with shaft turning in ball bearings, designed to guarantee notably low energy consumption and to provide 3 different air flow rates (the first two of which can be selected at the moment of installation)
• Air flow between 11.7 m3/h and 42 m3/h
• The appliance is equipped with an electronic circuit board and relative humidity sensor, allowing it to switch automatically from a previously set minimum air flow rate to the maximum setting. The pcb incorporates an electronic timer that shuts off the motor automatically when relative humidity returns below the threshold value. The timer setting is selectable during installation in the range 3’-20’ (default setting 3’).
