Filterite Claris Filters
Filterite Melt Blowing Expertise At Work
Filterite Claris Filters offer the most advanced melt blown filter cartridges available in the market today. From the innovative POLY-FINE® ARD with its layers of precisely defined melt blown sheets, to the Nexis with its patented CoLD® Fiber Technology, Filterite melt blown filters deliver the optimum solution for unsurpassed fluid cleanliness. The unique technologies, offered by Filterite, prove that we are the technological leader in melt blown filter manufacturing.
The patented production techniques and micro-processor controlled equipment result in the finest, most consistent, and reliable filters on the market. Recognizing that various applications have different cleanliness specifications, and therefore, different filtration requirements, Filterite strives to provide the best solution at the lowest possible cost. For highly critical applications, the absolute rated Poly-Fine ARD or NEXIS® A Series deliver the ultimate in depth filter retention coupled with long on-stream life.
For other critical applications, where absolute removal efficiencies are not required, the Nexis T Series offers highly consistent removal efficiencies with all the benefits of CoLD Technology at a somewhat lower overall cost. However, for many less critical applications, where general particle count reduction is desired at the lowest possible cost, the Claris filter now delivers the most economical solution.
The Case for Claris Filter Cartridges
Purity of Construction
Claris filter cartridges are constructed of 100% high purity polypropylene and are surfactant, binder and adhesive free. This chemically inert material of construction permits their use in a wide array of corrosive and non-corrosive applications. And, spent polypropylene cartridges can be readily incinerated to trace ash. Claris Series filter cartridges are extremely safe for use in critical applications. Tests indicate that the cartridges impart negligible levels of extractables and meet USP-XXIII Class VI plastics requirements. Finally, all materials used in the construction of Claris filter cartridges are listed for food and beverage contact by the US Food and Drug Administration.
Multiple fiber zones are created within the Claris filter to provide a graded pore structure throughout the depth of the filter. The different pore sizes allow for the efficient capture of various size particles throughout the depth of the filter medium. The result is maximum usage of the entire filter’s depth, for higher dirt holding capacity and long on-stream life. This gives the Claris filter a major competitive advantage over other melt blown filters with less gradients in their structure and over molded filters which feature virtually no pore size gradient.
E-Core Fibrous Extruded Core
The most unique feature of a Claris filter, requires a closer look inside. There, you will see an innovative center support structure, known as the E-Core. The patented E-Core replaces the injection molded center core found on many depth filters. By extruding a fibrous center core as part of the filter manufacturing process, we are able to more efficiently manufacture, and therefore, pass the savings along to you.
Yet the E-Core offers no compromises. Unlike coreless melt blown filters which use densely packed filtration fibers to create a support structure, the E-Core delivers high porosity and no flow restriction. And the E-Core delivers high collapse strength making it suitable for many applications. Finally, the E-Core does not reduce the amount of depth in your filter cartridge. Occupying about the same thickness as an injection molded core, the E-Core allows for an equivalent thickness of media to be formed on top, with no negative impact on the filter’s dirt holding capacity.
Clearly the Proof is in the Performance
To truly appreciate what has been achieved in the creation of the Claris filter, requires putting it on trial in your application. There, the benefits of the gradient pore structure, the consistent performance and the support afforded by the E-Core will speak for themselves.
Filterite Claris filters complete the Filterite product spectrum of melt blown depth filter cartridges. Claris is a general purpose filter that delivers consistent, reliable filtration at the lowest possible cost.
Filterite Claris filters Cartridges are constructed by collecting melt blown fibers of varying size on a unique patented* extruded fibrous core (E-Core).
