UFI PLEATED 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 .10-micron absolute. End cap configurations include DOE (double open end, flat gasket) and SOE (single open end, external double 222 O-ring/button end cap). Filter medias available include self-bonded fine diameter polypropylene fibers as well as membranes constructed of polypropylene, nylon, or PTEF.
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. They are most appropriate for use when high efficiency filtration and economy are crucial. To download our cut sheet, please click on the pdf icon below:

The UPE Cartridges are available in .25 to 250 microns and are stocked in 10-inch, 20-inch, 30-inch, and 40-inch lengths in both 2.75-inch and 4.5-inch outside diameter. Each 10-inch x 2.75-inch cartridge contains 4 square feet of durable, non-woven polyester fabric. Big Blue, 4.5-inch diameter cartridges contain 16 square feet of surface area. End caps, polypropylene core and polyester media are bonded into thermo-set vinyl plastisol which fuses all components into a single homogenous cartridge. Side seams are sonically welded to preclude bypass and improving efficiency. Washable, resistant to bacteria and chemicals and compatible with a wide range of filtration uses, the United Filters UPE Series Cartridges are ideally suited for residential and commercial/industrial applications.

PLEATED POLYESTER The chemical and bacteria resistance of the Series PE 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 reusable, while being pleated to maximize its dirt holding capacity and extending the time period between changes.
POLYPROPYLENE PLEATED FILTERS 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 (5) 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 having distinct dot patterns is employed on the outer three (3) layers to serve as a prefilter 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 (2) 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 the final particles on their inner layers. This design is an advancement in filtration technology and maximizes utilization of the filtration media while enhancing overall cartridge performance. Cartridge ends have been immersed in vinyl plastisol, creating a unitized end cap and gasket which virtually eliminates by-pass.

CELLULOSE PLEATED FILTERS are designed for general water filtration purposes. They are economical, yet highly effective, at reducing sediment particulates dowN to nominal 1 micron in size. 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. Custom sizes and end cap configurations available.
