3M™ Betafine™ PEG Series Filter Cartridge

Betafine PEG series filter cartridges effectively reduce the contaminating particles while maintaining or increasing process yields. These filter cartridges represent a major advance in pleated filter technology and performance that is built upon our history of filter design innovation. This absolute-rated, graded-porosity 100% polypropylene pleated cartridge features our highly effective Advanced Pleat Technology (APT) design that increases the usable filtration surface area while maintaining standard cartridge sizes. The result is a filter cartridge that has consistent performance and long service life.

ABCs of the APT Design
We developed our innovative Advanced Pleat Technology (APT) design to increase the service life of every Betafine™ PEG series filter cartridge. This design technology maximizes the useful surface area while maintaining open flow paths between media pleats. The design also supports a graded-porosity media structure, which results in lower pressure drops, longer service life and lower overall filtration costs. These filters are manufactured using our staggered pleat configuration that, when combined with a novel support material, provides more open space between the pleats. The increased open area of the staggered pleats allow for greater contaminant loading between each pleat at the inside diameter, while reduced-length pleats take advantage of existing open space closer to the outside diameter. The result is a fully usable surface area that provides superior service life.

Applications

Electronics Manufacturing

• Pre-reverse osmosis water filtration
• Plating and cleaning baths
• Complex multi-layer board processes

Fine Chemical Production

• Clarification of high purity chemicals
• Organic and inorganic chemical intermediates
• Various acids and bases
• Solvents and polymer solutions

Graded-Porosity — the Key to Longer Life
The Betafine™ PEG series filter cartridge's graded-porosity media structure reduces particles sequentially by size — the larger particles by the more open, outer medium and the smaller particles by the tighter, inner medium. The outer medium acts as a pre-filter, while the inner provides the absolute removal specified by the cartridge rating. Our unique construction effectively spreads the contaminant through the depth of the filter media resulting in high contaminant capacity with lower pressure drop for longer service life as compared to competitive filters.

Chemical Compatibility
Fine chemical production demands economical, rigorous filter cartridges with long service life. Our durable polypropylene construction provides broad chemical and mechanical compatibility for many demanding process fluid applications. Compatibility is influenced by process operating conditions; in critical applications, cartridges should be tested under actual conditions to determine the correct selection. We specifically designed, manufactured, and quality engineered Betafine™ PEG Series Filter Cartridges to meet the requirements of the electronics and fine chemical processing industry. The higher surface area of our exclusive APT design, our multi-layer, graded porosity media structure and broad chemical compatibility deliver the effective filtration you need while lowering your operational filtration costs.
