Pleated Filters

United Filters International Pleated Cartridge Filters are an alternative to string wound or spun molded filters. These filters are economical, multi-use, premium quality products that are available in various micron ratings ranging from 50 micron nominal down to 0.35 micron absolute. Filter medias available include, but are not limited to, polypropylene, polyester, and cellulose, as well as membranes constructed of polypropylene, nylon, PTFE, etc.

Pleated cartridge filters contain no surfactants or binders that can break down, leach out, or permit the typical problems of channeling and media migration. Maximum effective open surface areas allow for high flow rates at reduced pressure drop, as well as high dirt-holding capacity, long service life, large throughputs, and lower operating costs. These pleated cartridge filters may be used as either pre-filters or as final filters for bulk and point-of-use filtration, making them appropriate for use when high-efficiency filtration and economy are crucial.

AZURE-D™ is a unique broad spectrum anti-microbial polyester filtration media with Agion® technology inside, providing controlled long-term antimicrobial action, safety for drinking water, prevention of biofilm buildup, and durability in filter systems. With broad-spectrum efficacy, the media is active against bacteria, mold, mildew, fungi, biofilm formation, and some algae species over extended periods of time due to the carrier matrix that regulates the Agion® zeolite ion release.

Unlike coatings, AZURE-D™ and Agion® are incorporated into the polyester-based media structure, so the antimicrobial protection doesn’t wash off. It is compliant to NSF/ANSI 61/42 and EPA registrations for water treatment applications. The Agion® blended additive is NSF/ANSI standard 61 approved, EPA registration approved under 40 CFT152, and FDA GRAS recognized as safe for use in food and water system applications. It is not intended to sterilize water passing through.

For drinking water applications, utilize AZURE-D™ filtration media where submicron ratings are required for the removal of cryptosporidium and giardia cysts. Available in any pleated filter configuration available, UFI can design for any filtration needs, from standard filter designs to special and unique company-specific configurations. Durable filter designs maximize dirt holding capacity.

UFI JUMBO HIGH-FLOW (JB) Series filter cartridges are chemical- and bacteria-resistant noncellulose filters that are suitable for a wide range of industrial, well, and drinking water applications. The JUMBO HIGH-FLOW filter design allows for multiple sealing areas of the end caps that maximize utilization of the filtration media while enhancing overall cartridge performance with the center tube, end, and filter media thermally bonded as one unit. No separate O-rings are necessary, which prevents loss and concerns of form and fit within our unique sealing solution.

For drinking water applications, utilize AZURE-D™ or ULTRA-D® filtration media, where submicron ratings are required for the removal of cryptosporidium, giardia cysts and other contaminants. AZURE-D™ prevents microbiological growth on the media surface walls without influencing the quality of downstream water. The Agion® blended additive is NSF/ANSI standard 61 approved, EPA registration approved under 40 CFT152, and FDA GRAS recognized as safe for use in food and water system applications. It is not intended to sterilize water passing through.

They are available in a wide range of filtration media configurations, including pleated polyester (PE), pleated carbon (UCP), and our submicron filtration solutions of ULTRA-D® (USM) and AZURE-D™ (PEAZ). Durable filter design maximizes dirt holding capacity.

The pleated corrugated media provides increased surface area and strength, which results in extended life. End caps are fused to the cellulose media, preventing bypass and forming a gasket sealing area.

The chemical and bacteria resistance of the PE Series polyester media makes these cartridges suitable for potable water, most light industrial applications, swimming pool and spa, and well water applications. The durable, non-woven polyester fabric is both reusable and pleated to maximize its dirt holding capacity and extend the time period between changes.

PP Series polypropylene cartridges are designed for residential, commercial, and industrial filtration applications. Constructed of durable, chemical-resistant polypropylene media, they can be employed on many acids, alkalies, plating solutions, water remediation, and saline solutions. The cartridge filters employ a five layered, high-porosity bi-component polypropylene media consisting of both spun-bonded and melt blown polypropylene layers laminated together by ultrasonic sealing in order to provide depth filtration to the media. This depth filtration will allow the cartridge to collect more dirt particulate and, in most instances, offer a longer life.

The soft-spun bonded polypropylene with distinct dot patterns is employed on the outer three layers to serve as a pre-filter to reduce larger particles, while the smooth-textured melt blown polypropylene, which has been calendered in order to reduce the media pore size, is incorporated on the inner two layers for microfiltration. This arrangement of both the pre- and post-filter components provides two separate gradient layers in one filter. Gradient density filters reduce larger particles, which would blind-off ordinary surface filters on their outer layers, while reducing particles on their inner layers.
