    • A filtering device 10, 10' that has a fluid inlet 12, a plenum 14, first and second filter layers 16 and 18, first and second fluid outlets 20 and 22, and a housing 24. The plenum 14 receives air that passes through the fluid inlet 12, and the first and second filter layers 16 and 18 are located on opposing sides of the plenum 14. The first and second fluid outlets 20 and 22 are located downstream to the first and second filter layers 16 and 18, respectively, on a side of each filter layer 16, 18 opposite the plenum 14. The housing 12 supports the first and second filter layers 16, 18 on opposing sides of the plenum 14. Very good distribution of fluid through the device 10 may be achieved because the plenum 14 and the filtering layers 16, 18 maintain their original relative positioning throughout use. Complex shapes can be produced, which enable the filtering device to accommodate devices of various configurations. Thicker filter media beds may be used on each side of the plenum to improve filtration performance and service life.
    • 具有流体入口12,增压室14,第一和第二过滤层16和18,第一和第二流体出口20和22以及壳体24的过滤装置10,10'。集气室14接收通过 流体入口12以及第一和第二过滤层16和18位于增压室14的相对侧上。第一和第二流体出口20和22分别位于第一和第二过滤层16和18的下游 每个过滤层16,18与增压室14相对的一侧。壳体12在集气室14的相对侧上支撑第一和第二过滤层16,18。可以实现流体通过装置10的非常好的分布,因为气室 14和过滤层16,18在使用过程中保持其原始的相对定位。 可以产生复杂的形状,这使得过滤装置能够适应各种配置的装置。 可以在集气室的每一侧使用较厚的过滤介质床,以提高过滤性能和使用寿命。
