  • Legend
  • 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 fireproof casing KP 80 for flush mounting to wall.
  • Equipped with a 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 front panel is made of high-quality durable ABS plastic.
  • The turnable front panel conceals possible inaccuracies of the fan casing installation.
  • Energy efficient 2- or 3-speed motor on ball bearings with minimum energy demand.
  • Automatic maintaining of constant pressure and air flow 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.

  • Speed switch is performed with the external manual speed switch. P3-1-300 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 led out 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 works the protective cardboard plate is removed and the VNV-1 80 ventilation unit is installed into the casing that is connected to the wiring.
