  • Designation key
  • Continuous or periodic exhaust ventilation of bathroom, showers, kitchens, and other residential premises.
  • Ventilation of premises with high requirements to noise level.
  • Permanent low-speed operation mode ensures continuous air exchange in the room.
  • Ventilation shaft mounting or connection to Ø 100, 125 and 150 mm air ducts.
  • The casing and the impeller are made of highquality durable plastic, UV resistant.
  • The aerodynamic design of the impeller ensures high air flow and low noise level.
  • The fan is equipped with a specially designed backdraft damper to prevent back flow and heat losses during the fan standby.
  • The fan outlet spigot incorporates specially designed air rectifiers to reduce air turbulence, noise level and increase air pressure.
  • Low energy demand from 5 W due to a new twospeed high-efficient motor.
  • Ingress protection rating IP44.
  • Designed for continuous operation and requires no maintenance.
  • Equipped with overheating protection.

Manual control:

  • The fan is operated via a light switch (not included in the delivery set).
  • Speed control with a thyristor speed controller, refer to the Electric accessories. Speed controllers cannot be connected to the T1 and TH fan modifications.


  • Speed control with an electronic control unit BU-1-60, refer to the Electric accessories. The control unit is supplied separately.
  • By the T1 timer. When the external switch is turned on, the fan switches to a higher speed with a delay of 0 to 2 minutes. When the external switch is turned off, the fan will return to a low speed with a delay of 2 to 30 minutes.
  • By the humidity sensor and the TH timer. If the humidity level in the room exceeds the sensor threshold (60-90 %), the fan will automatically switch to a higher speed and will continue running until humidity returns to normal levels. Then the fan runs for 5 minutes at a high speed and switches to a low speed. The fan with a timer and TH humidity sensor can also be controlled in manual mode, for example, using the light switch. When the control voltage is applied, the turn-on delay timer is activated for 45 seconds and the fan switches to the second speed. After disconnecting the control voltage, the fan runs for a time set by the turn-off delay timer (from 2 to 30 minutes), and switches to the first speed.
  • The fan is mounted directly into the ventilation shaft.
  • Flexible duct connection is recommended in case of the remote ventilation shaft location. The air duct is connected to the fan exhaust flange through a clamp.
  • Wall fixing with screws.
  • Suitable for ceiling mounting.
