3M™ LifeASSURE™ BA Series Filter Cartridge membrane technology allows casting of an integral membrane onto a variety of substrates. The result is a microporous membrane with characteristics, such as increased flow and reduced pressure drop, tailored to provide ideal performance for the intended application.
The LifeASSURE™ BA series cartridge filter has 40% more surface area than competitive filters. Cartridge filter life is directly proportional to filter area and inversely proportional to face velocity (flow rate per filter area). For most beverages, when the filter area is doubled at the same flow rate, the throughput is increased by two and one-half times. The LifeASSURE™ BA series cartridge filter area is 20 to 50% higher than competitive filters, so the face velocity can be lower and throughput greater.
LifeASSURE™ BA series cartridge filters (PDF, 420.7 Kb) and LifeASSURE™ BLA series prefilter cartridges are both manufactured to withstand a mild alkaline flush after each days run (typically 30 minutes of forward recirculation
