APPLICATIONS |
|
|
|
- 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.
