The 3M Betafine PEG series filter cartridge represents a major advance in pleated filter technology and performance. Building on 3M Purification’s history of filter design innovation, this absolute-rated, graded-porosity 100% polypropylene pleated filter cartridge features Advanced Pleat Technology (APT) that increases the usable filtration surface area while maintaining standard cartridge dimensions. The result is a filter cartridge that has dramatically enhances service life.
Advanced Pleat Technology (APT)
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 where the pleats are packed most tightly. The Betafine PEG series filter 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.
