VENTILODICE V & VC
Fire resistant air transfer grilles
Based on powerful intumescent technology, the rectangular (V) or circular (VC) air transfer /ventilation grilles, VENTILODCE, are ideally placed for the natural ventilation through fire resistant partitions or doors.
These fire resistant air transfer grilles are developed to allow the free circulation of air at room temperature through construction elements (walls, doors etc.) while at the same time offering effective protection against flames, smoke and gases in case of fire.
When the grilles are exposed to fire, the intumescent blades expand under the effect of the heat and prevent flames, smoke and gases from passing through.
VENTILODICE grilles are available in rectangular shape (Ventilodice V) and circular shape (Ventilodice VC).
VENTILODICE grilles are available in various sizes and thicknesses, making them suitable for all types of applications.
Standard color: grey (for other colors please consult us).
Standard dimensions:
Thicknesses: 25, 40, 50, 60 mm.
VENTILODICE V nominal width and height: from 100mm to 600mm.
VENTILODICE VC nominal diameter: from 100 mm to 400 mm. (Ø125mm also available)
VENTILODICE V&VC grilles are manufactured by steps of 50mm (consult us if specific dimensions are required).
Fire resistance: EI-30, Ei-60, EI-90, EI-120.
The fire resistant air transfer grilles VENTILODICE V&VC react at low temperature (from 100°C). The intumescent blades expand under the effect of the heat and prevent flames, smoke and gases from passing through.
The pictures hereunder show the VENTILODICE V grille after 120 minutes of fire test. First photo - view of the grille on the fire side, second - view on the non-fire side.
The actual dimensions of the VENTILODICE V & VC grilles (heights and widths) are always 3 mm smaller than nominal dimensions. Any fitting clearances of up to 4 - 5 mm must be filled using ACRYLODICE F intumescent sealant.
VENTILODICE grilles suit mainly for indoor applications (avoid contact with water, high humidity and temperatures >40ºC).
Examples of applications for Vision fire resistant air transfer grilles VENTILODICE V & VC: Fire resistant doors, fire resistant walls, fire resistant partitions.
