Sun ind international supplies wind-driven roof top ventilator named turbovent.It is used for clean, green and economical industrial ventilation. The power of wind as well as stack effect is used to drive the machine. The power of the air is generated by the movement of air in the buildings due to a difference in indoor-to-outdoor air density caused by temperature and vapour pressure differences. For that it does not energy to run. It has no operational and maintenance costs if its is installed after proper pre analysis. The durability of the ventilator also depends on the pre analysis. The pre analysis means the study of the process, climatic conditions, geography, etc. Stainless steel, aluminium and titanium are used to manufacture the ventilator. Sizes available are 16" and 24" in diameter and 13" and 21.5" in height. The vibration is reduced by the precision balanced low inertia head design material. It can be installed in metal, asbestos, and fibreglass roofs. This roof top ventilator comprises custom built welded adapter. The ventilator is leak proof and noise-free, and can withstand wind of up to 140 km/hr.
