Above, let Xiaobian to tell you about the task principle and advantages of unpowered fans.
上面，就让小编来给大家讲讲无动力风机的任务原理和优点吧。
The unpowered fan is the application of air convection stop task, the blade of the unpowered fan into a certain arc, the air is constantly active, will promote the rotation of the stainless steel hood, at the same time of its rotation, drive the indoor air rise, slow down the air update, to adhere to the effect of fresh indoor air dust removal and smoke exhaust.
无动力风机是应用空气对流停止任务，无动力风机的叶片成一定的弧度，空气不停的活动，会推进不锈钢风帽的转动，在其转动的同时，带动那个室内空气上升，减速空气更新，到达坚持室内空气清新除尘排烟的效果。
Weatherproof characteristics: circular arc blades, each blade and the gap between the blades, rotating blades complement each other to fill this gap, a small amount of rain along the circular node line thrown out, a small amount of rain along the blade and the roof, will not flow into the turbine, at the same time, the rotating turbine makes the air out of the blade gap, preventing rain into the.
防风雨特性： 圆弧形叶片，每一叶片与叶片之间有空隙，旋转时叶片相互补位把这此空隙填补，少量雨水延着圆的节线抛出，小量雨水则 延着叶和片流落屋顶，不会流入涡轮里，同时旋转的涡轮使空气由叶片间隙流出，阻挠雨水进入。
