摘要： An air filtration system comprises an airflow inverter valve, an internal diffuser and a cylindrical filtration element positioned between the airflow inverter valve and the internal diffuser. A frustoconical external diffuser is joined to the airflow inverter valve so as to at least partly surround the filtration element. If desired, the airflow inverter valve and the external diffuser may be built as a single monolithic member. In one example, the airflow inverter valve, internal diffuser, filtration element and external diffuser each have a central axis of rotation aligned along a common central axis of the air filtration system.

摘要翻译： 空气过滤系统包括气流逆变阀，内部扩散器和位于气流逆变阀和内部扩散器之间的圆柱形过滤元件。 截头圆锥形的外部扩散器连接到气流逆变器阀，以至少部分地围绕过滤元件。 如果需要，气流逆变阀和外部扩散器可以构建为单个整体构件。 在一个示例中，气流逆变阀，内部扩散器，过滤元件和外部扩散器各自具有沿着空气过滤系统的共同中心轴线对准的中心旋转轴线。
