Eaton”s Duplex POLYLINE Bag Filters have no metal components to rust or corrode, and their one-piece polypropylene molded filter housing bodies have no seams, welds, or crevices to trap particles. The filters do not require flow shut down for filter bag changeouts, as a quarter-turn of the operating lever diverts the flow from one filter housing to the other through a CPVC plastic valve assembly that allows the process to continuously run during bag changeouts. Suited for automated or remote operation. The filter housing covers are hand removable and feature an all-plastic, built-in vent valve with an integral gauge tap. The inlet and outlet connections can be adapted to both in-line and loop piping arrangements for application flexibility. An integral plastic mounting skid, standard with all POLYLINE Duplex Bag Filters, simplifies installation. Available in sizes for standard number 1, single length or number 2, double-length filter bags in polypropylene construction with CPVC valve assemblies.
