Multi-zone microporous Nylon 6,6 membrane.

By eliminating dual-layer membrane construction, this multi-zone structure provides a larger surface area, a significantly increased contaminant holding capacity and a long service life. It has an open zone that acts as a pre-filter by capturing larger particles and colloids on the upstream side of the membrane and a tighter zone on the downstream side that retains smaller contaminants to maintain high retention efficiency.

Advanced Pleat Technology (APT).

3M’s APT design helps to maximize the useful surface area of the filter while maintaining open flow paths between the media pleats. It also provides lower pressure drops, a longer service life and lower overall operational costs.

100% integrity tested.

Users can integrity test 3M™ LifeASSURE™ BLA Series Filter Cartridges for bubble point, diffusive flow or pressure hold procedures while the filters are in the housing to ensure proper installation and operation.

Extensive food contact compliance.*

3M™ LifeASSURE™ BLA Series Filter Cartridges can be used for a variety of food and beverage filtration applications including wine, beer, water, soft drinks, syrups, dyes and intermediates.
