Application
1. Innovative exhaust fan with stylish design for new comfort level in shower rooms, bathrooms, kitchens and other residential premises.
2. Maximum air capacity combined with low noise level provide the ideal microclimate.
3. Mounting into ventilation shafts or connection to Ø 100 mm.
Design
1. Casing, impeller and frontpanels made of high-quality and durable UV-resistant plastic.
2. Specially designed impeller aerodynamic profile provides high air capacity and low noise.
3. The compact design enables wall and ceiling mounting.
4. The shortened spigot for mounting into a ventilation shaft or connection to Ø 100 mm air ducts.
5. The fan is equipped with a specially designed back valve to prevent back flow and heat losses during the fan standby.
6. The fan exhaust spigot incorporates specially designed air rectifiers to reduce air turbulence, increase air pressure and lower noise level.
7. High ingress protection rating ensures makes the fan the ideal solution for ventilation of a bathroom. The electronic components are protected with tight covers.
Mounting
1. Installation directly inside a ventilation shaft.
2. Flexible air ducts may be used in case of remote location of the ventilation shaft. Connection of the air duct to the exhaust flange with a clamp.
3. Wall mounting with screws.
4. Suitable for ceiling mounting.
Motor
1. Low energy demand 7.5 W due to new highefficient motor.
2. Maintenance-free bearings contain enough grease for 40 000 hrs non-stop operation.
3. Motor on special anti-vibration dampers for vibration absorbing and silent operation.
4. Motor equipped with overheating protection.
Speed Control
Manual:
1. The fan is controlled by a room light switch. It is not included in the delivery set.
2. The fan is controlled by the built-in pull cord switch V. Not applied in case of ceiling mounting.
3. 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 Т, ТН, ТР, VТ, VТН modifications.
Automatic:
1. By the BU-1-60 electronic control unit. The control unit is supplied separately.
2. 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).
3. By the humidity sensor and the TH timer (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).
