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.

 

The DUOLINE bag filters are based upon the TOPLINE, SIDELINE and FLOWLINE bag filter vessels.  The TOPLINE style is recommended for absolute rated retention filter bag applications; the SIDELINE version is best for nominal (most common) filter bag retentions and the FLOWLINE version does not have an ASME code stamp option, it's the "economy" version.  You can review each of their respective webpages for a more detailed description of which version is best for your application.

 

The MODULINE, PROLINE and MAXILINE multiple chamber bag filter vessels have from 3 to 24 filter bag chambers for higher flow rate applications.

 

If you require spare parts for an existing DUOLINE bag filter, please refer to the replacement parts pages for the TOPLINE, SIDELINE or FLOWLINE style - depending upon which version you have.
