Dual/duplex Bag Housing

Duplex /dual Bag housing are used when the system flow cannot be shut down for bag cleaning or change out. A Dual type bag filter can operate continuously without shut down. The Dual/Duplex bag system consists of two single bag filter housings fitted together at the inlet and outlet by either a butterfly or ball valve assembly. Valve assemblies are connected together by a center post handle assembly in order to guarantee a synchronized change from filter A to filter B. A quick turn of the handle diverts the flow from one filter housing to the other. The filtration process runs continuously during bag change-outs.
