Centrifugal fan VENTS VNV-1 80 KP

Application

• 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.

Design

• 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.

Motor

• 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.

Front panel modifications

Mounting example

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.

Options for 2 speed fan models

• TR — adjustable timer modification
• I — interval switch modification
• F — built-in photosensor modification
• Н — humidity sensor modification
