Description
Description
APPLICATION  
  • Exhaust ventilation of high-rise residential and non-residential premises with increased fire prevention requirements.
  • Mounting in kitchens, bathrooms, toilets, storerooms and other household areas.
DESIGN  
  • For wall surface mounting.
  • The front panel and the casing are made of high-quality durable ABS plastic.
  • Equipped with maintenance-free fireretarding damper. As the temperature in the shaft reaches 90°С the thermal fuse melts and the damper shuts automatically hot air access off, and the flame and smoke ingress to the room though the ventilation shaft system is prevented.
  • For easy mounting the damper is mounted on a pivot rod. First mount the damper to the wall and then fix the fan casing (see mounting examples).
  • The fire-retarding damper serves as a backdraft damper when the fan is off and prevents air moving from the ventilation shaft.
  • Connected with the main ventilation shaft with a flexible air duct.
  • Connecting branch pipe diameter 80 mm.
MOTOR  
  • Energy-efficient 2-speed motor on ball bearings with minimum energy demand.
  • Independent maintenance of pressure and air flow rate in the duct.
  • For precise characteristics, low noise level and safe operation each turbine is dynamically balanced while assembly.

Name Description
T
timer modification
The fan is switched on to the maximum speed manually with the external switch, turn-on delay time is 50 seconds. The return to default position is performed with the timer, run-out time is 6 minutes. Continuous low speed operation is possible.
TR
adjustable timer modification
The fan can be switched to the maximum speed manually with the external switch. Turn-on delay time is set with the internal regulator ranging from 0 to 150 seconds. Run-out time is set with the internal regulator from 2 to 30 minutes. Continuous low speed operation is possible.
I
interval switch modification
The fan switches periodically to the maximum speed while operation. The switching interval is set by means of the internal regulator ranging between 0.5 and 15 hours. Run-out time is 10 minutes. The fan can be switched manually with the external switch, turn-on delay time is 50 seconds. Continuous low speed operation is possible.
H
humidity sensor modification
The fan switches to the maximum speed as relative humidity level in the room increases. It switches off as relative humidity level drops by 10 % below the set level. The humidity threshold is adjusted in the range between 60 % and 90 %. Force switching to the maximum speed is provided, in this case the turn-on delay time is 50 seconds, and the run-out time is set by the internal regulator between 2 and 30 minutes. Continuous low speed operation is possible.
