Vents 100 MA is a household fan with automatically closing blinds. Designed for wall or ceiling installation. The peculiarity of this fan is that when the fan is turned on, the blinds on the front grille open, and when the fan is turned off, the blinds smoothly close. Thus, the ventilation duct is blocked when the fan is not working, which prevents air from entering the ventilation shaft into the room being served.

Automatic:

• Using an electronic control unit BU-1-60(see Electrical accessories). The control unit is supplied separately.
• Using a timer “T” (the built-in adjustable shutdown delay timer allows the fan to operate for 2 to 30 minutes after it is stopped by the switch). li>
• Using a humidity sensor and a timer “ТН” (if the humidity in the room exceeds the value set on the sensor of 60-90%, the fan will automatically turn on and continue operating until the humidity will return to normal, then the fan works out the time set on the timer and turns off).
• Using a motion sensor and timer “TR” (if the sensor detects movement in its area of action, then the fan will automatically turn on and continue working on a timer from 2 to 30 minutes Detection range up to 4 meters (detection angle max. 100°).

Installation

• The fan is installed directly into the opening of the ventilation shaft.
• When the ventilation shaft is located remotely, it is possible to use flexible air ducts. The air duct is connected to the fan outlet flange using a clamp.
