The rotation principle of wind driven turbo ventilators ※The sphere could work through hot air rise inside and hot air discharge from the chink of twenty-      four blades. ※The power come from the air discharge from inside to outside and the temperature range and          pressure difference    between inside and outside. ※Breeze could bring air pressure to drive the sphere. Therefore, ventilators run without consuming    electricity.

免電力通風器轉動原理 ※藉由室內熱氣上升，熱氣自24片葉片縫隙排出，驅動主機球體運轉。 ※室內氣流由內往外排出，室內外溫差壓及氣壓差，產生動能。 ※戶外微風形成壓力使主機球體驅動，完全不需電力。
