Facet CC-U5-2DP Series coalescer cartridges are designed for removing free and entrained water from BTEX compounds-xylene, benzene, toluene and ethylbenzene, or removing BTEX compounds from water. When removing water, a two-stage housing using Facet's synthetic separator cartridges as the second stage will greatly improve efficiency. When removing BTEX compounds from water, use the CC-U5-2DP in a single-stage housing.This coalescer cartridge is constructed of a single piece fiberglass tube, stainless steel metal components and non-asbestos gaskets. It is 6" (152 mm) OD, by 3 1/2" (89 mm) ID by 14 1/2" (370 mm) long which makes it interchangeable with most 6" (152 mm) OD coalescer cartridges.
