Turbo Ventilator

We have a concept in the wind operated Turbo Ventilator. This is new product for use in proper ventilation of pitched roof construction including industrial sheds, commercial buildings, farm houses etc. Turbo Ventilator is a wind operated ventilator installed on the roof and is rotated by the wind, the stale air inside is exhausted through the vanes and a natural inward flow of fresh air is boosted. We are the pioneers in wind driven ventilation in northern India. Turbine air ventilator works without electricity, it runs on wind velocity and it work hours a day and 365 days a year ,it doesn't require any kind of maintenance once installed and there are no accidents like fire due to short circuit shocks.
