Plastic casing KVK 80

Application

• Casing for the ventilation unit VNV-1 80.
• Suitable for premises with mono-pipe ventilation system.
• Mounting in kitchens, bathrooms, toilets, storerooms and other household areas.

Design

• Installed into a wall during construction works.
• Equipped with maintenance-free fire-retarding damper to prevent fire and smoke penetration along the air ducts.
• 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.
• Made of high-quality durable ABS plastic.
• Connected to the main ventilation shaft with a flexible air duct.
• Connecting branch pipe diameter 80 mm.

• Supplied with the protective cardboard plate to protect the casing from dirt and dust penetration during construction and finishing works in the room.
• In case of adjacent 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 adjacent room is used
