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.
The fire resistance rating is E90/І60 for the KP 80 casing and EІ90 for the KP2 80 casing.
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.
KP casing
KP2 casing
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.
Installation of an extra branch pipe into the
fireproof casing can only be made at the
factory and therefore must be specified when
ordering.
If fan in fireproof casing is to be mounted
into a ceiling, this must be indicated when
ordering the product in order to ensure
correct positioning of the fire-resisting
damper at the factory.
FIRE-RESISTING 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.
