Description

APPLICATION
Continuous or periodic exhaust ventilation of bathroom, showers, kitchens and other utility spaces. Ventilation shaft mounting or duct connection.	Low to medium air flow motion for short distances at low air resistance. Compatible with Ø 100, 125 and 150 mm air ducts.
DESIGN
Modern design and aesthetic look. The casing and the impeller are made of highquality durable ABS plastic, UV resistant.	The intellectual impeller design makes the fan efficiency high and the service life long. Protection rating IP24.
MOTOR
Reliable and low-watt electric motor. Designed for continuous operation and requires no maintenance.	Equipped with overheating protection.
CONTROL
Manual: The fan is controlled by a room light switch. It is not included in the delivery set. The fan is controlled by the built-in pull cord switch V. Not applied in case of ceiling mounting. Speed control is possible through a thyristor speed controller (see Electrical Accessories). Several fans may be connected to the same controller. Speed controllers can not be connected to the fans with T, TH, TP, VT, VTH modifications.	Automatic: By the BU-1-60. electronic control unit. The control unit is supplied separately. By the T timer (the built-in turn-off delay timer enables the fan operation within 2 to 30 minutes after the fan switching off). By the humidity sensor and the TH timer (if the humidity level in the room exceeds the sensor threshold value adjustable 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 it shuts down).
MOUNTING FEATURES
The fan is mounted directly into the ventilation shaft. In case of remote location of the ventilation shaft, flexible air ducts may be used. The air duct is connected to the fan exhaust flange through a clamp. Fixed to the wall by means of screws.	Suitable for ceiling mounting. To connect a fan with a 12 V low voltage motor to 220 V/50 Hz power mains, it is necessary to purchase a step-down transformer (e.g. the TRF 220/12-25 transformer).
