Small fan MiniVent M1/150, with 2 power levels (260/220 m³/h), energy-saving EC motor and humidity control. Run-on time can be set to approx. 6, 12, 18, 24 minutes, the time function can be set to either the high or low power level. It is also possible to activate the time functions on both power levels. Each level can be set to a speed range from min. to max. using a potentiometer. The switch-on threshold for the dehumidification function is set from 40% - 95% using another potentiometer. In addition to time functions, the 8-pin DIP switch provides a wide range of adjustable functions such as humostat function, level assignment of the time functions, dehumidification. Three different dehumidification functions can be set: 1-level: single-level dehumidification, power level can be selected, 2-level: dehumidification starts at a low power level. When the humidity increases, the fan automatically switches to the high power level, steplessly: the speed of the fan is based on the humidity in the room. With its excellent design, MiniVent M 1 fits harmoniously anywhere - even in sophisticated rooms. The closed, elegant facade completely prevents the dirty fan opening from being seen. Equipped as standard with a tightly closing return air flap. Thanks to the new ultraSilence technology, the noise level is 35 dB(A) at 220 m³/h volume flow. Universally applicable for the ventilation of bathrooms, toilets and other rooms.
