Multirow Source Stacked Fan

Gallery / Feature Showcase

A source section spanning three grid rows feeds three vertically stacked downstream sections through one right-exit port, while an in-section terminal forces the exiting lines onto a bypass. The three lines descend together from the trunk to the lower exit row over a diagonal flattened toward 45 degrees, so they read as distinct parallel tracks rather than fusing into one stroke on a near-vertical drop.
