Automatic release smoke natural vents

Brand: RVI

The Orion is En 12101-2 and CE certified for smoke exhaust natural ventilation systems. Its automatic release opening system through an actuator will open up the blades to evacuate smoke from a building in case of fire. It can also be used for natural ventilation through a manual or mechanized "Open & Close" function.
The vent can be linked to a rain sensor for ease of natural ventilation usage. We recommend that bird mesh be used for each vent, which can also be protected with burglar bars.

This roof ventilator is designed to extract smoke from the interior of a building through automatically operable roof-mounted ventilators.
