Omnipure K5755-JJ - 14" In-Line Deionization Water Filter

Mixed Bed Ion Exchange Process for Ultra-High Purity Water

Omnipure K5755JJ is a self-contained inline DI filter containing mixed bed dionization resin for producing ultrapure water with a mininum TOC Background.  Ideal for use in an RODI system as a polishing filter to polish the RO product water, Omnipure K5755-JJ DI Filter has 1/4" quick connect fittings on each end for direct connection to the tubing leading to the dispensing faucet.  The large 2.5" x 14" contains 42.4 cubic inches of deionization resin, with a DI capacity of 310 grains - almost 40% more than a standard 10" Filter.  Omnipures Mixed Bed Deionizer Replacement Filters can be used in many major brands of laboratory water systems including Aquamax, Millipore, Barnstead, Labconco and Continental/US Filter laboratory water purification systems.  The in-line installation allows for the filters to be easily added to an existing RO system to provide an additional stage of polishing.

Omnipure’s K Series filter body features 1/4" Quick-Connect™ fittings, allowing for fast, simple, hassle-free installation, and replacement. These fittings are molded directly into the filter body and cap as a single unit, reducing the chance for weeping or seepage. Cap and body are spin-welded together producing a smooth, consistent seal without the use of glues or binders that can cause contamination.  One of the primary uses of this product is as a system component. The benefit is derived from the fitting being molded directly into the filter cap, greatly reducing clearance.

The direct in-line installation eliminates the need for an additional housing.

Benefits of Omnipure K5755 Deionization Filters

  • High Capacity:  The larger 2.5" x 14" filter body  holds 42.2 cubic inches of media for a Di capaciyt of 310 grains - nearly 40% higher than a standard 10" DI filter.
  • Point-of-Use: Unobtrusively added to the water source quickly and easily.
  • Disposable: The filter is a self-contained capsule that is simply discarded at the end of service life. NO mess. No hassles.
  • Inexpensive: A point-of-use filter makes for cost-effective water filtration. By filtering the water being used for drinking, laboratory, or other purposes, the user saves a tremendous amount of money over whole-house filtration. 
  • Made in USA:   The Omnipure production complex is a state-of-the-art facility constructed and organized to implement the manufacturing techniques that make the Omnipure products the finest in the world.
