Glad you found it helpful! It was originally going to be just a one-off video, but based on the interest I'm going to order a Ryco Syntec for a future video. I plan to get the same model as what was in the comparison so I'll be able to compare it to the Penrite. Thanks for your support!
Would think that's normal. Fluid is flowing through the filter, and it's only at the ends where it's folded that fluid flow is perpendicular to the element. The rest of the time it's running pretty well parallel. So any heavy stuff's going to be pulled along and hit the wall where it's folded.
