The invention relates to a filter device having a stepped filter consisting of separate filter elements arranged in fluid series, through which two flow paths for a flow of air extend, wherein the first flow path extends through at least two of the individual filter elements such that the individual filter elements can be flowed through by air, and wherein the second flow path extends through a single individual filter element such that the single individual filter element can be flowed through by air; an air flap arranged upstream or downstream of the stepped filter, by means of which a first of the air streams and/or a second of the air streams are guided through the stepped filter along a first flow path or along a second flow path. The invention also relates to a method for operating such a filter device.

    本发明涉及一种过滤装置,其具有:阶梯式过滤器,该阶梯式过滤器由流体串联设置的独立过滤元件组成,用于空气的气流的两个流动路径延伸穿过该阶梯式过滤器,其中第一流动路径延伸穿过这些独立过滤元件中的至少两个独立过滤元件,使得这些独立过滤元件能够被空气流过,其中第二流动路径延伸穿过单个独立过滤元件,使得该单个独立过滤元件能够被空气流过;设置在阶梯式过滤器的上游或下游的空气瓣,借助于该空气瓣,这些气流中的空气的第一气流和/或这些气流中的空气的第二气流沿第一流动路径或者沿第二流动路径引导穿过阶梯式过滤器。本发明还涉及一种操作这种过滤装置的方法。
