Vital Dome S
The patented device Vital Dome S slides totally overhanging on one side, letting vent surface free to improve air, smoke gas and heat flowing. It doesn't need other actuators for daily opening to air exchanging.



Vital Dome R
Vital Dome R is the overturning natural vent device. It can permit air exchanging only with the addition of an electric device.


Both "S/R" systems work using the same concept: pneumatic actuators feed by dedicated compressed gas bomb, activated by thermal valve set at 68°C, 93°C or 110°C. The remote opening (manual or automatic), can be made by oneway electric system like pyrotechnic actuator; using electromagnetic rearm able multipurpose valve, or pneumatic plant controlled by BOX having different function levels.
