Verified by manufacturer 3 months ago
Automatic opening vent (AOV) to reduce smoke and heat, with a choice of glazing types.
Application
To reduce smoke and heat in the case of fires, and to enable escape.
Description
Features and benefits:
- In addition to effective air flow when operational, the automatic opening vents resist weather penetration and provide appropriate thermal insulation when closed.
- Can be used with simple control systems linked to smoke detectors, networked systems or centralized control panels.
- Manufactured in accordance with EN 12101-2.
- High performance U-value.
- Can be with exposed actuators or concealed actuators.
- Wide range of bespoke sizes from 700x600mm to 1500x2500mm.
Operation and ventilation options include;
- 140° opening AOV (1500mm maximum span/opening width).
- Electrically operated.
