“Wind ventilators” are eco-friendly, Zero power consuming turbo-vaned to evacuate hot air from the enclosed area and make the working better for workmen and lower the temperatures (4 – 5 Deg. C) by inducing more air changes in the area but also improves the efficiency of most of the operating machines like compressors, condensers etc. “Wind Ventilators” works by utilizing wind power induced by centrifugal action. The temperatures (4 – 5 Deg. C) by inducing more air changes in the area but also improves the efficiency of most of the operating machines like compressors, condensers etc.
