Particle Filter Element Prefilter element for the removal of particulate contaminants in gases. Ultraporex B Ultraporex Type B Prefilter Element Donaldson Ultraporex B prefilter elements utilize a highly porus sintered media for absolute filtration of particles down to 25 ìm in size. The primary filtration mechanism of this media is sieving, which captures most particles near the surface allowing for regeneration of the element and reduced operating cost through fewer element change-outs. Although the Ultraporex B is primarily used as a particulate prefilter, a simple reversal of flow through the element allows the Ultraporex B to be used as an effective course coalescing filter element, removing bulk quantities of water and oil from an air or gas stream (standard housings are equipped with an internal float drain, so no special equipment is required). The high-grade sintered bronze media ensures not only a high load capacity of contaminants, but also long life through its resistance to aggressive condensates and its ability to be regenerated many times. Applications The Donaldson Ultraporex B filter element is ideal in the following industries and applications: • Particulate prefilters upstream of final filters • Centralized prefiltration in compressor rooms • Course coalescing after cyclone separators and before fine coalescers • Installations with aggressive condensates AirCel™ ™ Element Type Flow Rate 100 psi (cfm)* 0035 20 0070 41 0120 70 0210 123 0320 188 0450 264 0600 353 0750 441 1100 647 Operating Pressure psi Conversion Factor fp 15 0.25 30 0.36 45 0.50 60 0.60 75 0.75 90 0.90 100 1.00 115 1.10 130 1.20 150 1.40 160 1.50 175 1.60 190 1.75 200 1.90 220 2.00 250 2.10 *cfm related to 15 psi abs. and 68°F Sizing example for pressure which deviates from nominal pressure: Vnom = 200 cfm, operating pressure = 130 psi Vcorr = Vnom /fp Vcorr = 200 cfm / 1.25 = 165 cfm Calculated Size: Type 0320
