How wind ventilator works

The turbine ventilator operates by utilising the velocity energy of the wind to induce air flow by centrifugal action The centrifugal force caused by the spinning vanes creates a region of low pressure area which draws air out theough the turbine. Air drawn out by the turbine is continuously replaced by fresh air from the outside.

The slightest breeze will cause the turbine ro spin and even after the breeze has stopped, the fly wheel effect of the rotor cage will use its stored energy to continuously remove air giving rise to ventilation. Suction is maintained even at low wind velocities. Hot air becomes lighter and accumulates at the center apex of the shed. MotorisedExhaust Fans prove to be ineffective as they are unable to extract air from the apex of the Factory Shed. Mostly these fans are installed on walls and near windows and doors sucking most of the air from the outside and throwing it back again. The process and equipments continue to release odour, fumes even after factory shut down. These motorized fans cannot run 24 x 7 without being overheated and breaking down. Even if they do run 24 x 7 the cost of electricity would become prohibitive.
