Duplex bag filter housings are designed with two sets single bag filter housings fitted together at the inlet and outlet by a butterfly valve or ball valve. This increases flow capacity and allows the filtration process to run continuously even during filter bag change-outs.
All single-bag series of Seadon can be assembled into duplex units. These vessels are available in 304 stainless steel, and 316L stainless steel, polypropylene in flange or NPT/BSP styles.
