DUOLINE bag filter housings consist of two #2 size filter bag chambers for a maximum flow rate of approximately 360 GPM for nominal filtration of water-like fluids. When one #2 size bag filter is not enough for your flow rate and the HAYFLOW upgrade option† isn't viable, consider the DUOLINE.
† increases maximum flow rate of a #2 size housing from approximately 180 GPM to 300 GPM for nominal retention of water-like fluids. NOTE: you can apply the HAYFLOW upgrade option to the DUOLINE bag filter vessels to increase their flow capacity further.
This differs from a duplex bag filter housing, which has valves to divert flow from one side to the other; the DOULINE bag filter housings are simply a multiple chamber (just 2) bag filer housing to support higher flow rates than a single #2 size housing would support. The MODULINE, PROLINE and MAXILINE multiple chamber bag filter vessels have 3 to 24 #2 size filter bag chambers in support of even higher flow rate applications.
The DUOLINE bag filters are based upon the TOPLINE, SIDELINE, FLOWLINE and FLOWLINEII bag filter vessels. The TOPLINE style is recommended for ≤ 25 micron nominal and absolute rated retention filter bag applications. The SIDELINE and FLOWLINE versions are best for > 25 micron nominal filter bag retentions, with the SIDELINE available with an ASME code stamp. Review the filter housing page for each variation to better understand the design differences.
