Abstract
A fill pack includes a first fill sheet defining an air intake edge, an air exit edge and an airflow axis extending between the air intake edge and the air exit edge. The first fill sheet defines a first flute section having a first inlet end, a first outlet end and a first peak extending between the first inlet end and the first outlet end. A second fill sheet defines a second flute section having a second inlet end, a second outlet end and a second peak extending between the second inlet end and the second outlet end. The first peak extends relative to the second peak such that a first flute portion defined by the first and second flute sections has a cross-sectional shape that changes between the first and second inlet ends and the first and second outlet ends.
