The Curvent Fire-X 1620 fire ventilator is a louvred bladed 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 fully waterproof system in the closed position. In the event of fire, the spring loaded louvres automatically open to 90°, causing a “chimney effect” to allow hot gasses to escape, preventing fire spread while protecting the building’s structural integrity against building collapse. The smokeless layer of fresh air created at lower level creates 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 Curvent Fire-X 1620 Lumina range with translucent louvre blades adds natural light and the patented translucent blades refracts ultra violet light to limit heat build-up to buildings with the assurance of a highly effective fire ventilator, designed to save lives. The Curvent Fire-X 1620 fire 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.
