Ventilation is must for any industry for safe, efficient, effective working and maintaining a healthy environment for employees. A World Health Organization (WHO) study in 1984 reported that almost 30% of the new and modified construction is facing a problem of poor indoor air quality. A turbo ventilator is an alternative to motor driven ventilating systems and operates on natural wind energy and which is used as common ventilation device due to its affordable price, more efficiency, simple operating mechanism and low maintenance cost. Turbo ventilators are maintenance free and sustainable solution in providing comfortable indoor environment for buildings. In this paper detailed studyabout the current improvements and future scope of the turbo ventilator is done. The results of analytical and the experimental works are analyzed by considering its performance for the various applications. The combined device i.e. turbo ventilator with internal blades on central shaft shows the best results. Performance of the modified combined turbo ventilator with throat diameter 600 mm was found to be better than that of the other turbo ventilator.
