Compressed Air Industry FOOD PROCESSING | 03/08 | Service life of coalescing filter elements are determined by the amount of solid contamination that is collected. Solid particulate is removed in equal efficiency to that of liquids, yet behave differently after collection. Solid particulates do not coalesce and become a permanent contaminant within the element. Due to the inherent benefit of the vacuum formation design, particles are trapped through entire cross section of the filter, lowering pressure drop, maximizing solid loading capacity and increasing service life of the element. 6 A non-wicking fiberglass media wrap is added to the outer diameter of the support core. The support core enhances the structural integrity of the element. Cores made of either rigid, high impact plastic or corrosion resistant steel are selected based upon customer requirements. After formation of the filter core, the element is cured through a heating process. Proper dehydration time allows the core to stabilize and become suitable for further handling. A non-wicking, polyester drain layer is added. Multi-staging the element with a dedicated drain layer prevents re-entrainment of liquid. Elements with plastic support cores are precisely cut to desired length. Element length must conform to physical dimensions of the respective filter housing. Magnified cross section of borosilicate fiber 7 8 9 10 An optional 3.0 micron pleated pre-filter is placed into the internal diameter of the inner support core. The added media layer extends the service life of the coalescing filter by removing solid contamination. A metal, corrosion resistant support screen is added to maintain the mechanical integrity of the pleated media under back flow conditions. 11 End caps are bonded to the element, which facilitate insertion into the filter housing. End caps made of anodized aluminum, plastic, silicone or urethane, are customer specified. 12 After sufficient curing time of the bonding agent, the elements’ part number is diamond etched on the bottom end cap. 13 The product is placed is a heat sealed transparent wrap, placed in a shipping carton, then placed on the shelf as finished goods available for service. Ultra Air Delta Series high-performance filtration products are equipped with vacuum formed filter elements. Micro-Filtration also utilizes the vacuum formation process when manufacturing a comprehensive range of Upgrade compressed air filter elements.
