Betaﬁ ne™ XL Series

Absolute-Rated Pleated Poylpropylene Filter Cartridges

The Betafine XL filter represents a major advance in pleated filter technology . Building on CUNO’s history of filter design innovation, this absolute-rated, 100% polypropylene, pleated cartridge features an Advanced Pleat Technology (APT) that increases the usable filtration surface area while maintaining standard industrial cartridge dimensions. The result is a filter cartridge that dramatically enhances service life.

Advanced Pleat Technology

The service life of a pleated cartridge is often dictated by the accessible surface area. Conventional pleated filters may offer a large gross surface area, but when the media is packed too tightly into the cartridge, only part of the surface area is usable resulting in both flow restrictions and limited contaminant holding capacity. The “blind” or unusable area commonly occurs near the inside diameter (see figures below) where the pleats are packed most tightly. The Betafine XL cartridge is manufactured using a staggered pleat configuration that, when combined with a novel support material, provides more open space between the pleats.

The APT staggered pleats with increased open area allow for greater contaminant loading between pleats at the inside diameter, while the reduced length pleats take advantage of existing open space closer to the cartridge’s outside diameter. The result is a fully used surface area that provides superior service life.

Betaﬁ ne XL Advanced Pleat Technology utilizes a conﬁ guration designed to increase the accessible surface area for signiﬁ cantly greater ﬁ lter media use.

Conventional pleat designs, with full-depth densely packed pleats, ﬁ ll the upstream pleat surface with contaminant that quickly constrict ﬂ ow at the pleat’s inside diameter.

Superior Service Life

Extensive testing has demonstrated that the Betafine XL filter provides service life superior to competitive pleated filters of equivalent removal ratings when subjected to the same contaminant load. The result of using filters with significantly longer service life is substantially reduced filtration costs. Betafine XL filters provide a service life improvement of up to 4.4 times greater than competitive products! (Graph 1 )

Superior on-line service life provides significant total filtration cost reductions. From fewer filter cartridges used to a reduction in labor costs by decresing filter change-out frequency, Betafine XL filters provide the ultimate in cost effective pleated filter technology.

The Impact of Service Life on Total Filtration Costs

The service life of a filter has a direct impact on total annual filtration costs. To illustrate how great an impact can occur, the follo wing example is provided. The example is based on a model system with a flow rate of 250 gpm using 18 (30” long ) filter cartridges with a change-out frequency of one week.

Absolute Ratings

The assurance of predictable and reproducible contaminant removal can best be provided by the use of absolute-rated filters. Betafine XL filters are absolute rated to Beta 1000 (99.9% efficiency at its rating) and are available in 9 distinct ratings from 0.2 micron to 70 micron. This provides a complete choice of ratings to meet the exacting filtration requirements for the most critical applications.

Filter Cartridge Construction

Betafine XL filters, constructed of 1 00% polypropylene, provide excellent chemical and thermal compatibility. The filter media is constructed from continuous micro-fibers that are precisely controlled to provide a uniform matrix and consistent effluent quality. Betafine XL filter incorporates a polypropylene support upstream and downstream of the media to provide optimum flow characteristics and long service life. The all-polypropylene cartridge components are thermally bonded — no resin or binder compounds are used. All materials used in the manufacture of Betafine XL filters are FDA CRF Title 2 1 listed for direct food contact. Available in 9 distinct micron ratings and integral lengths

from 9 ing designs, Betafine XL cartridges are ideal for a wide variety of applications.
