Skylights are widely Wind operated Turbo ventilator is 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. Turbo Air ventilators work without electricity, it runs on wind velocity and it works 24 x 365 days a year. Turbo ventilator system functions and performs with the unlimited energy source like wind Skylights Turbo Ventilators used in daylighting design in residential and commercial buildings, mainly because they are the most effective source of daylight on a unit area basis. energy thus saving running cost of exhaust fans, wiring, maintenance etc. Wind Turbo ventilator does not require operating time, it continuously rotates with the wind , removes moisture laden air in the winter and extremely hot air in the summer. Turbo Ventilators provide energy free cooling and fresh air throughout the year.
