  • Options
  • Dimensions
  • Innovative exhaust fan with stylish design for new comfort level in shower rooms, bathrooms, kitchens and other residential premises.
  • Maximum air capacity combined with low noise level provide the ideal microclimate.
  • Mounting into ventilation shafts or connection to Ø 100 mm.
  • Casing, impeller and frontpanels made of high-quality and durable UV-resistant plastic.
  • Specially designed impeller aerodynamic profile provides high air capacity and low noise.
  • The compact design enables wall and ceiling mounting.
  • The shortened spigot for mounting into a ventilation shaft or connection to Ø 100 mm air ducts.
  • The fan is equipped with a specially designed back valve to prevent back flow and heat losses during the fan standby.
  • The fan exhaust spigot incorporates specially designed air rectifiers to reduce air turbulence, increase air pressure and lower noise level.
  • High ingress protection rating ensures makes the fan the ideal solution for ventilation of a bathroom. The electronic components are protected with tight covers.
  • Low energy demand 7.5 W due to new highefficient motor.
  • Maintenance-free bearings contain enough grease for 40 000 hrs non-stop operation.
  • Motor on special anti-vibration dampers for vibration absorbing and silent operation.
  • Motor equipped with overheating protection.

Manual control:

  • Manual control with a room light switch. The switch is not included into 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 connected to the same controller. Speed controllers can not be connected to the fans with TTHVTVTH modification.

Automatic control:

  • By the electronic control unit BU-1-60. 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 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 set time period and shuts down).
  • Installation directly inside a ventilation shaft.
  • 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.
  • Wall mounting with screws.
  • Suitable for ceiling mounting.
