Allied Group's new type of coalescing filter is constructed of three layers. The inner and outer layer act as a built-in pre-filter, according to flow. This is also the drain layer and support layers. The middle layer, "binder free" borosilicate fiber/microglass, is the coalescing portion of the filter. The pre-filter removes large quantities of dirt particles before entering the coalescing part, thereby increasing the life of the filter. Efficiencies range from 93% to 99.9999% at the 0.3 micron range and rated to over 5000 psi.The pre-filter can be constructed with microns from 1 to 75. We will custom design for new applications or cross reference competitive filters for existing applications.
