3M DP290 Dual Port Manifold System: The Gold Standard in Commercial Water Filtration

Seamless Multi-Application Water Filtration

The 3M DP290 Dual Port Manifold System takes commercial water filtration to new heights, offering the versatility and performance you need for various applications—be it ice, coffee, or cold beverages. Capable of handling a combined flow rate of up to 10 gpm, this powerful system provides dual streams with tailored filtration to suit each application’s specific needs.

Enhanced Beverage Quality and Equipment Protection

One stream focuses on scale inhibition, reducing the chances of calcium and magnesium build-up on essential components like ice machine evaporator plates and coffee brewer heating coils. The other stream targets cold beverage dispensers, reducing particulate, chloramines, and chlorine taste and odor but leaving out the scale inhibitor. This way, the 3M DP290 dual port system not only ensures the highest quality in your beverages but also minimizes the wear and tear on your machinery.

Easy Maintenance and Reliable Performance

With its Sanitary Quick Change (SQC) feature, cartridge replacement becomes a breeze, negating the need for a filter wrench and reducing maintenance time. The dual port system delivers the benefits of multiple equipment filtration in one compact package—simplifying your water filtration solution.

  • One system with dual outlet connections simultaneously supplies cold beverage dispensers and ice machines/coffee brewers.
  • Up to 10 gpm (37.9 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.
