• Ventilation shaft mounting or duct connection.

• Low to medium air flow motion for short distances at low air resistance.
• Compatible with 100, 125 and 150 mm air ducts.

• A battery-powered quartz clock is built into the fan casing.
• Both Arabic and Roman hour plates are available on the front panel.
• Modern design and aesthetic look.

• Reliable and low-watt electric motor.
• Designed for continuous operation and requires no maintenance.

• Equipped with overheating protection.

Manual:

• The fan is controlled by a room light switch. It is not included in the delivery package.
• Speed control is possible through a thyristor speed controller (see Electrical Accessories). Several fans may connected to the same controller. Speed controllers can not be connected to the fans with T, TH, TP, VT, VTH modification.

Automatic:

• By the electronic control unit BU-1-60 (see Electrical Accessories). The control unit is supplied separately.
• By the timer T (the built-in run-out timer enables the fan operation within 2 to 30 minutes after the fan switching off).
• By the humidity sensor and timer TH (if the humidity level in the room exceeds the sensor threshold adjustable value within 60-90% the fan switches automatically on and operates until the humidity level drops to the standard level, after that the fan continues operating within the time period according to the timer setting, then shuts down).

• The fan is mounted directly into the ventilation shaft.
• Flexible duct application is recommended in case of remote location of the ventilation shaft. The air duct is connected to the fan exhaust flange through a clamp.

• Fixed to the wall by self-tapping screws.
• For 12 V low-voltage motor fan connection to 220 V / 50 Hz power mains use the step-down transformer TRF 220/12-25 that is available upon separate order.
