MODIFICATIONS

Models of this series can be equipped with extra options:

Name	Description	Icon
Alta L	The unit is equipped with a motor on ball bearings to increase its service life (ca. 40 000 working hours). The bearings are maintenance-free and are filled with grease for the whole motor service life. This motor allows to mount the fan at any angle.
Alta T	The fan is equipped with a motor on ball bearings. The bearings are maintenance-free and are filled with grease for the whole motor service life. This motor allows to mount the fan at any angle.
Alta TH	The fan is equipped with an adjustable turn-off delay timer and a humidity sensor. The integrated humidity sensor controls the fan’s operation based on the indoor humidity level. If the set humidity level is exceeded, the fan is autonomously triggered and operates until the humidity level is normal. When the normal level is reached, the fan keeps working until the timer countdown is up and turns off.
Alta V	The fan is equipped with a pull cord switch to be turned on and off manually.
Alta VT	The fan is equipped with a turn-off delay timer and a pull cord switch. A built-in turn-off delay timer allows to prolong the fan’s operation for 2 to 30 minutes after it is switched off. This allows to reduce humidity and remove unpleasant smell.
Alta VTH	The fan is equipped with a pull cord switch, an adjustable turn-off delay timer and a humidity sensor. The fan can be switched on via the pull cord or autonomously after triggering the humidity sensor. When the preset humidity level is reached, the built-in turn-off delay timer countdown starts.
Alta TR	The fan is equipped with an adjustable turn-off delay timer and a motion sensor. The fan starts operating after motion is detected in the sensor triggering zone ( 1 - 4 m, FOV - up to 100°). When the motion stops, the turn-off delay timer starts.
Alta 12	The fan is equipped with a low-voltage (12 V) motor, which allows to use the fan safely in humid rooms, and places with high risk of water exposure (bathrooms, saunas etc.)
