  • Options description
  • Exhaust ventilation of high-rise residential and non-residential premises with increased fire prevention requirements.
  • Suitable for premises with mono-pipe ventilation system.
  • Mounting in kitchens, bathrooms, toilets, storerooms and other household areas.
  • Supplied in plastic casing KVK 80 for flush mounting to wall.
  • The front panel is made of high-quality durable ABS plastic.
  • Equipped with maintenance-free fire-retarding damper. As the temperature in the shaft reaches 90°С the thermal fuse melts and the damper shuts automatically hot air access off, so the flame and smoke penetration though the ventilation shaft system is prevented.
  • The fire-retarding damper serves as a backdraft damper when the fan is off and prevents air moving from the ventilation shaft.
  • The turnable front panel conceals possible inaccuracies of the fan casing installation.
  • Connected with the main ventilation shaft with a flexible air duct.
  • Connecting branch pipe diameter 80 mm.
  • Energy-efficient 2-speed motor on ball bearings with minimum energy demand.
  • Independent maintenance of pressure and air flow rate in the duct.
  • Fastened to the casing by means of latches with no tools.
  • For precise characteristics, low noise level and safe operation each turbine is dynamically balanced while assembly.
VNV-1A(E) 80 KVK T — the fan is equipped with a timer and a fire-resisting damper.
VNV-1A(E) 80 KVK TR — the fan is equipped with an adjustable timer and a fire-resisting damper.

VNV-1A(E) 80 KVK I — the fan is equipped with an interval switch and a fire-resisting damper.
VNV-1A(E) 80 KVK H — the fan is equipped with a humidity sensor and a fire-resisting damper.

  • The case perforations allow connecting extra branch pipes for second room ventilation system. In case of second room ventilation system the casing is perforated for extra branch pipes for exhaust ventilation of the adjacent room. Remove a plug in the casing to connect extra branch pipe.
  • Speed switch is performed with the external manual switch. P3-1-300 speed switch for the three speed fan models and P2-1-300 for the two speed fan models. The speed switches are not included into the delivery set and are available upon order.
  • The fan casing is mounted during construction works and connected to the main ventilation shaft.
  • Electric wiring for connection of the VNV-1 80 ventilation unit is routed through a special hole in the casing.
  • The front panel is covered with the protective cardboard plate supplied with the unit to avoid damages or contamination during finishing works in the room.
  • After finishing the repair works the protective cardboard plate is removed and the VNV-1 80 ventilation unit is installed into the casing and connected to the wiring.

Name Description
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.
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.
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.
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.
