Centrifugal fan VENTS VNV-1 80 KP

• 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-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.

VNV-1A(E) 80 KP T — the fan is equipped with a timer.
VNV-1A(E) 80 KP TR — the fan is equipped with an adjustable timer.

VNV-1A(E) 80 KP I — the fan is equipped with an interval switch. 
VNV-1A(E) 80 KP H — the fan is equipped with a humidity sensor.

• In case of second room ventilation system the casing is equipped with extra branch pipes with three air duct layout modifications for adjacent room ventilation.
• In such a case the kit for exhaust ventilation of the adjacent room is used.

VNV-1A(E) 80 KP-D — the fan is equipped with a extra branch pipe on the bottom.

• 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.
