  Features

DUOLINE filter housings are for applications where the system flow cannot be shut down for filter bag change out. Either a butterfly or ball valve assembly is used to divert the flow between the two housings so that the isolated, out of service, housing can be serviced. The flow is never shut down.

An integral valve linkage assembly is available for DUOLINE housings with butterfly valves that permits operation of the valves with a single handle.

Features/Benefits

  • Can be equipped with the most advanced TOPLINE™ single bag filter housing, the SIDELINE™ single bag filter housing for a greater range of applications, or the economical FLOWLINE™ single bag filter housing for coarse particle filtration.
  • System arrangement assures continuous flow rates. One unit can be taken off-line in sequence for filter bag change-outs without having to take the other filter unit off-line.
  • Swing bolt cover for quick, easy filter bag change-outs. The TOPLINE single bag filter housing features a domed cover. FLOWLINE and SIDELINE single bag filter housings covers feature an integrated ergonomic handle.
  • TOPLINE and SIDELINE models feature extended five year warranties and are designed in accordance with Section VIII, Division 1 of the ASME Code (standard in the US), “AD 2000-Merkblätter”, EN 13445 and PED (standard in EMEA).
  • Smooth, bead-blasted finish makes it easy to completely clean the interior.

DUOLINE housings are available in carbon steel or stainless steel for size 02 (double length) filter bags. End connections are either 2" or 3" flanged.

Options

  • Housings and fittings available in stainless steel for high corrosion resistance. Carbon steel versions available in the US.
  • Available without valves, with butterfly valves or with ball valve assemblies.
  • Buna-N® O-rings for the cover are standard. EPDM, Viton®, PTFE encapsulated Viton or silicone rubber seals and gaskets are available.
  • Linkage assembly available. A quick turn of the linkage handle diverts the flow from one single bag filter housing to the other, guaranteeing a synchronized changeover.

Applications

  • Automotive
  • Food and Beverage
  • Chemical Processing
  • Paints, Inks, Resins and Coatings
  • Electronics
  • Petrochemicals
  • Municipal Water Treatment
  • Industrial Water Treatment
  • Pulp and Paper
  • Pharmaceutical
