Suitable for utilization on various kerbs and domes. The vents are manufactured according to EN-ISO 9001 quality control standards and comply with the European requirements for NSHE according to EN 12101-2. The vents are formed from high quality corrosion resistant aluminium to ensure low maintenance requirements and watertightness. 

Various methods of operation using pneumatic or electric actuators are available. COVIA RA is a perfect solution for preventive fire protection in staircase rooms and can also work as a roof access system. Within the range on the minimum and maximum possible construction sizes, the devices can be supplied in variable dimensions.
