Features & Benefits

Multi-Zone Naturally Hydrophilic Nylon 6,6 Membrane

• No IPA pre-wetting and system flushing required — avoids a potential source

of contamination and chemical interaction, while reducing downtime and hazardous

waste disposal

• Reduces potential for microbubble formation by not dewetting in outgassing fluid

unlike hydrophobic membranes such as Polypropylene, Polyethylene, and PTFE

• Enhanced contaminant reduction capacity results in longer lifetime than competitive

filter cartridges

• Economic alternative to PTFE filter cartridges

Advanced Pleat Technology

• Superior flow characteristics in a compact design reduces the number of require

filter elements

• Increased flow rates provide faster bath clean-up and reduced energy consumption

• Provides a low differential pressure to minimize micro-bubble formation

• Increased throughput and filter lifetime which lowers cost-of-ownership

Series Filter Cartridge

6,6 filter elements designed to meet the exacting requirements of DI water, critical

parts cleaning, and chemical applications. Utilizing multi-zone microporous membrane

and Advanced Pleat Technology (APT), LifeASSURE IMC filter cartridges provide superior

flow characteristics with minimal pressure drop. Increasing flow while maintaining filter

efficiency results in particle specifications being achieved in less time. This decrease in

processing time results in lower total filtration costs — reduced energy consumption,

pump wear, and labor.

The naturally hydrophilic Nylon 6,6 membrane in an all polypropylene construction,

provides low extractables, increased filter life, and superior contaminant reduction as

compared to other membrane cartridges. LifeASSURE IMC filter cartridges are ideally

suited for DI water, critical parts cleaning, and numerous chemical applications where

high efficiency contaminant reduction at 0.1 μm, 0.2 μm and 0.45 μm is required.

Multi-zone Microporous Membrane Technology

LifeASSURE IMC filter cartridges incorporate 3M Purification’s multi-zone microporous

membrane technology to maximize contaminant holding capacity while maintaining

particle reduction efficiency. Microporous membrane consists of a higher porosity (more

open) zone on the up stream section and a lower porosity (tighter) section on the down

stream side. The higher porosity zone on the up stream side provides effective pre-

filtration of large particles resulting in higher contaminant reduction capacity and

increased filter life time. The lower porosity zone on the down stream section provides

a sharp retention cut-off at the rated pore size. As shown in SEM micro graph (Figure 1)

the multi-zone structure enhances the surface area, lowers pressure drop, and increases

contaminant holding capacity and filter lifetime thereby eliminating the need for more

costly filters constructed with a double layer of membrane.
