Abstract

In an inside-out flow filter, a transition pressure recovery member is provided at the inlet and has structured contoured guide surfaces guiding fluid flow therealong into the hollow interior of an annular filter element to minimize transition pressure loss from the inlet to the hollow interior. The transition pressure recovery member includes transition flow deceleration surfaces gradually decelerating flow of fluid into the hollow interior and minimizing pressure drop.
