Permatron products feature the unique Accumulator Chamber® construction for effective and efficient filtration. Years of experience, many thousands of filters and independent laboratory tests have proven that the engineering design of Permatron air filters enables them to outperform the competition.
Each one and two inch thick Permatron filter represents a miniature filter bank; there are in fact two filters in one. The outer steel frame holds two 1/4” panels also housed in steel frames. The three-frame construction, although lightweight, maintains strong support and assures that the media is firmly held in place even over long, hard use.
Between the two filter panels in an air space that is 1/2” wide on a one-inch filter, and 1 1/2” wide on a two-inch filter. This is our exclusive Accumulator Chamber.
Permatron woven filter media allows air to flow through, enhancing its electrostatic charge. This media never loses its charge, as it is an inherent property. The airborne particulates are attracted to the media fibers like iron filings to a magnet. The particulates, attracted to the fibers in the direction of air flow, build up on the fibers without face loading.
If an excess of particulates builds up (due to high concentrations in the air, or failure to clean the filter regularly) on the prefilter, they tend to break off, allowing air flow to sweep them through the prefilter into the Accumulator Chamber. Cross currents within the Accumulator Chamber cause further agglomeration and some settlement until the filter is rinsed. The afterfilter (back panel) attracts and holds particles that escape the prefilter or do not respond to and electrostatic charge.
InfiniPleat is a back panel filter designed with the every property to stop particulate in it’s tracks. Together Permatron and InfiniPleat create a double defense.
