Datasheet: Betafine XL Series Prefilter

Providing Reduced Total Filtration Costs and Predictable Filtration Performance

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 a patented 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 to provide:

• Reduced Total Filtration Costs - Fewer cartridges used, reduced cartridge change-out frequency, reduced downtime and product waste, and reduced labor and disposal costs.
• Predictable filtration performance - Reduced quality checks, reduced product rejects and rework, and increased productivity and plant capacity

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 to right) where the pleats are packed most tightly. The Betafine XL cartridge is manufactured using a patent pending 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.
