Description
Description
APPLICATIONS  
  • Continuous or periodic exhaust ventilation of bathroom, showers, kitchens and other utility spaces.
  • Ventilation of premises with high noise level limitations.
  • Mounting into ventilation shafts or connection to Ø100, 125 and 150 mm air ducts.   
DESIGN  
  • The casing and the impeller are made of highquality durable ABS plastic, UV resistant.
  • Specially designed impeller aerodynamic profile provides high air capacity and low noise.
  • The fan is equipped with a 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.
MOTOR  
  • Low energy demand from 8 W due to new high-efficient motor.
  • Protection rating IP 44.
  • Designed for continuous operation and requires no maintenance.
  • Motor equipped with overheating protection.
CONTROL  

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 T, TH, TP, VT, VTH modification.

Automatic:

  • 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 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).
MOUNTING FEATURES  
  • 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 wall by self-tapping screws.
  • Suitable for ceiling mounting.
