PULSE FILTER DESIGN
A filter element includes a first filter portion extending between a first end and an opposing second end. The first filter portion includes a first cross-sectional dimension that is substantially constant along a length of the first filter portion between the first end and the second end. The filter element includes a second filter portion extending between a third end and an opposing fourth end with the third end being located adjacent the second end. The third end has a third end cross-sectional dimension that substantially matches the first cross-sectional dimension. The fourth end has a fourth end cross-sectional dimension that is smaller than the third end cross-sectional dimension.
