Fireproof casing KP 80

Application

• Exhaust ventilation of multi-storey residential and public premises with high fire safety requirements.
• Casing for ventilation unit VNV-1 80.
• Suitable for premises with mono-pipe ventilation system.
• Mounting in kitchens, bathrooms, toilets, storerooms and other household areas.

Design

• Designed to prevent penetration of flame products through ventilation shafts into the premises in case of fire.
• Fire resistance rating is E90/160.
• Equipped with a maintenance-free fire-retarding damper and fireproof casing.
• Made of silicate plates manufactured by special cement technology based on calcium silicate.
• The plates contain no asbestos and have high mechanical and insulation properties. High hygroscopic and vapor permeable features provide humidity regulation by the material itself.
• Installed into a wall during construction works.
• Connected with the main ventilation shaft with a flexible air duct.
• Сonnecting branch pipe diameter 80 mm.
  

  

• The ventilation unit is fastened to the casing by means of latches with no tools.
• Supplied with the protective cardboard plate to protect the casing from dirt and dust penetration during construction and finishing works in the room.

Modifications and options

• In case of two-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.

Fire damper

• Prevents smoke and fire propagation through the air ducts in case of fire.
• 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 damper plate is made of stainless steel.
• Operates as a backdraft damper when the fan is off and prevents air flow from the ventilation shaft.
