ABSTRACT OF DISCLOSURE The specification discloses an improved wrapped fiber felt drain layer for use in conjunction with one or more filter layers and/or a plastic retaining tube, in whatever order desired, to provide improved drainage for coalescing filter tube constructions. The wrapping of said drain layer is not limited to circular filter tubes, but may be used on filters of square or rectangular cross section and the like, and also on filter constructions of pleated cross section, there being no practicable limit as to the cross section of the filter assembly on which the drain layer can be mounted. Additionally, such drain layers can be used both on in-to-out and out-to-in filter constructions.
