安德烈亚过滤器由两片折叠的实心纸板组成,它们以弯曲的方式粘在一起。在前面的开口是不对称的位置对开口在后墙。当空气通过过滤器时,气流在各个轴上都发生变化。在后壁上,v字形的深度弯曲形成了凹槽,用来捕获分离的液体颗粒。原理:充满液体颗粒(如油漆)的气流在通过过滤器时被加速,并成倍改变其方向。比空气重的粒子由于惯性从气流中分离出来。空气通过过滤器的出口开口逸出,而油漆颗粒则积聚在捕获室中。优点:涂料在气流外的积累减缓了压力和空气流速差异的增加。Andreae过滤器的寿命比平片、羊毛过滤器长3-5倍。过滤器在气流中显示出高稳定性。 The front V-shape wall prevents the reflection of overspray. The employee remains in a clean environment and the air stream around the sprayed objects is stable. The folded structure of filters is very strong, it resists suction of ventilation and does not collapse even when it is relatively full. Filters with easy and quick exchange. They reduce operating costs for maintenance of spray booths.
