FIRE-X 1620


The Curvent Fire-X 1620 fire ventilator is a louvre bladed slope mounted fire ventilator with a low-profile design to enhance the architectural aesthetics of any building. The louvred blades are designed to close individually over its own rain channel, providing a waterproof system in the closed position. In the event of fire, the spring loaded louvred blades open automatically to allow hot gasses to exhaust. This will aid in the building’s structural integrity against collapse.  


The smokeless layer of fresh air created at lower level creates a safe evacuation passage for people and assists in firefighting disciplines. Natural day-to-day ventilation is made possible with the addition of electromechanical or pneumatic operating systems or Curvent Pinnacle Roof Turbine ventilators. The ventilator is renowned for its versatility. It provides for large ventilation areas, and can be custom-built to suit most steel structures, roof profiles and specific design requirements
