3M™ Water Filtration Filter Dual Port System DP390. 1/case


Sale priceCAD $2,150.00


The 3M Model DP390 dual port water filtration systems help provide consistent high quality water for the multiple applications of cold beverages, ice and coffee at a combined flow rate of up to 15 gpm (56.8 lpm). Two separate streams exit the manifold. Both streams have reduced sediment and chlorine taste and odor. One stream has added scale inhibition media from a dedicated cartridge to help reduce the ability of calcium and magnesium to precipitate as hard scale on the evaporator plates of an ice machine and/or the heating coils of a coffee brewer. The second stream supplies cold beverage dispensers and includes no added scale inhibitor. The DP390 filters combine chlorine taste and odor reduction with cyst, bacteria and sediment reduction to 0.2 micron


  • One system with dual outlet connections simultaneously supplies cold beverage dispensers and ice machines/coffee brewers.
  • Up to 15 gpm (56.8 lpm) total flow of water especially treated for consistent great tasting cold beverages, clearer and consistent ice and the perfect cup of coffee or tea
  • Revolutionary Integrated Membrane Pre-Activated Carbon Technology (“IMPACT”)
    dual-zone media cartridge construction combines a membrane in series with premium activated carbon to provide superior throughput and cartridge life.
  • Reduction of up to 99.99% of common water-borne heterotrophic bacteria by membrane filtration as tested by 3M Purification (HF90 replacement cartridge).
  • NSF and/or FDA CFR-21 compliant materials.
  • Built-in bacteria inhibitor intended to reduce fouling of media (HF90 replacement cartridge)
  • Reduction of scale build-up on evaporator plates and heating coils from a controlled forced-feed orifice addition of scale inhibitor, as tested by 3M Purification.
  • Sanitary Quick Change (SQC) encapsulated cartridge design allows for fast and easy cartridge change-outs with a 1/4 turn.
  • 3/4” NPT horizontal inlet and outlet ports allow direct or easily adaptable connections to existing plumbing lines.
  • Expansion kit available to serve higher capacities and flow rates
  • Auxiliary inlet gauge port allows optional monitoring of differential water pressure.
  • Manifold includes outlet check valves and vent valve.
