The high-performance gravity roof ventilation system delivers twice the capacity of conventional systems of the same size, while its optimized design provides a structure that is approximately 30% lighter. Featuring a positive-direction hood and vertically corrugated cladding, the system offers effective self-cleaning properties. With a high discharge coefficient of Cvo = 0.70, it demonstrates superior performance in industrial buildings with heavy heat loads. Maintaining high efficiency even under extreme climatic conditions, the RIF-P is an ideal solution for high-volume industrial ventilation applications and corrosion-resistant environments.
