Definitions
- this layer of standard batting would suffer severely from the surface loading effect since the presence of the metal plate would actually reduce the surface area of the batting due to its intimate contact with the batting.
- the expanded batting 12 includes an upper entrance surface 36 and a lower exit surface 38. Expanded batting 12 is attached to the upper surface 40 of continuous batting layer 16 to form the composite fluid filter 10. Preferably, expanded batting 12 is glued or laminated to second layer 16, such that the force of a fluid stream on the upper surface 40 of the second layer 16 will not separate the first and second layers.
- the cross-sectional view of fluid filter 10 shows expanded batting 12 attached to second layer batting 16, with openings 14 extending from entrance surface 36 to the upper surface 40 of second layer 16. Arrows 42 are schematic representations of fluid flow through filter 10, with particulate 44 indicated within fluid flow arrows 42 prior to passage through filter 10.
