Abstract
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.
