However, the fundamental problem with finer fibres is that they are just finer fibres. Very little about their composition, shape or ability to be formed into a web alters the aforementioned relationship that exists between pressure drop, flow rate and retention. If anything it makes it worse since smaller fibres in a web results in smaller interspatial void volume (pores) with the media becoming more of a highly retentive surface filter with limited loading capacity, reduced flow rate and increased pressure drop.
Ahlstrom’s Disruptor™ technology is capable of shattering the relationship between increased pressure drop and decreased flow rate as retention is increased. This is possible because Disruptor™ technology represents a breakthrough in materials science that synergistically combines the best aspects of charged and mechanical filtration in one media. The patented technology behind Disruptor™ is was invented by Fred Tepper and Leo Kaledin  of the Argonide Corporation and is manufactured and sold by Ahlstrom under an exclusive, global license.
