Description: Turbine air ventilators based on new technology are offered without power or operating costs. These turbine air ventilators improve working conditions and increase productivity; are easy to install and can be fitted to any type of roofing; can be configured to meet required fresh air changes; they run on wind power; are weather and storm proof; economical and ecological; maintenance free; work on thermal currents, centrifugal force to exhaust and turbo design create suction; sturdy, light weight, slight breeze enough to rotate ventilator; and temperature-resistant alloy steel materials. The turbine air ventilator works by utilising the wind energy to induce air flow by centrifugal action. The centrifugal force caused by the spinning winds creates a region of low pressure area which draws air out through the turbine. Air drawn out by the turbine is continuously replaced by fresh air from outside. The slightest breeze will make the turbine to spin and even after the breeze has stopped, the flywheel effect of the rotor cage will use it continuously to remove air, giving rise to ventilation. Suction is maintained even at low wind velocity. Advantages of these turbine air ventilators include no maintenance cost; no electricity charges; no accidental hazards like fire due to shortcircuits, electrical shocks; low cost of installation; assured ventilation for 24 hrs/365 days; protects food products and chemicals; and 100% depreciation under Sec 32 of IT act. These turbine air ventilators are offered by Blaze Engineers.
