Abstract
A filter element for filtering a fluid that comprises a pleated filter media and a support structure. The pleated filter media comprises pleats that define an upstream gap along an upstream surface of the pleated filter media and a downstream gap along a downstream surface of the pleated filter media. The support structure extends along the downstream surface of the pleated filter media and supports the pleats. The support structure is folded into two layers comprising a first layer and a second layer within the downstream gap. The first layer inner surface and the second layer inner surface are positioned adjacent to each other within the downstream gap. The support structure comprises at least one spacer that increases a distance between the first layer outer surface and the second layer outer surface such that the differential pressure drop through portion of the support structure that is within the downstream gap is decreased.
