Parker Hannifin CorporationFiltration and Separation DivisionOxford, MIOPERATIONAir coalescing is a continuous, balanced, steady-state process occuring ator below rated flow, which depends on two factors for high performance:(1) The bowl must be kept free of waste liquid build-up and (2) The elementmust be replaced when the differential pressure reaches 6-10 psid, 12 psidmaximum. Differential pressure can be sensed at the inlet and outletports by two gauges, or by observing system characteristics.Bowl draining is accomplished by slowly opening the manual drain valves,at least once every 8 hours depending on the liquid load. Finite's new HighPressure Drain Kits are useful tools that can be utilized in order to safelydrain condensate from a high-pressure air / gas system. See Finite BulletinNP024 for more details.A Finite coalescer, under normal system conditions, will operate for 6 to12 months before reaching its maximum differential pressure. With shortercoalescing element life a "PWC" series Particulate or"WS" Water Separa-tor element should be employed ahead of the coalescer to increase its life.A precoalescer (Grade 10) can also be used to extend the life of the highefficiency coalescer (Grade 4).Finite coalescers are designed for nominal operation with 10-20 wt.oil. Anyviscosity increase over that of 20 wt. oil must be offset by a proportionateoversizing of the filter element. Consult your Finite representative.PROBLEM PROBABLE CAUSE SOLUTIONToo High Initial Air flow excessive for housing size. Install larger filter.Pressure Drop Filter media grade too fine. Install coarser element.Too much oil/water from compressor. Pre-coalesce with grade 10 - oversizehousing.Premature Clogging Lubricant improperly selected for compressor, Change oil, consult with lubricant(Air Flow Drops Off) causing varnish or carbonizing of lubricant. supplier.Excessive inlet particulate contamination. Prefilter with Particulate Filter.Excessive lubricants present on element caused Prefilter with Grade 10 or 100WS andby either high lubricant viscosity or very high oversize coalescer to compensate.inlet aerosol level.Oil/water emulsion forming on element.

The filter should be installed at the highest pressureavailable, as near as possible to the equipment to be protected. It should also havea drip leg immediately upstream. All filters should be visible and easily accessiblefor periodic draining and maintenance.The filters should be piped in accordance with the instruction tags and flow arrows.Should these tags become unreadable, install the coalescer and water separator sothat flow passes through the filter tube from inside-to-outside. Plumb particulateand adsorber filters so that flow passes through the filter from outside-to-inside.The filter locations relative to other equipment should be as follows (unless specificinstructions are given to the contrary): (1 ) The COALESCER is placed beforethe dryer.(2) The PARTICULATE or WATER SEPARATOR goes ahead of theCOALESCER when prefiltration is required. (3) The PARTICULATE is installeddownstream of desiccant dryers to prevent desiccant migration.(4) The ADSORBERand DESICCANT CARTRIDGE are always preceded by a COALESCER.MAINTENANCEWhen Coalescer or Interceptor differential pressure reaches clogged condition(6-10 PSID) replace element immediately. DO NOT ATTEMPT TO CLEANFILTER TUBE. System contamination can result. DO NOT ATTEMPT TORESEAT A FILTER TUBE. New serrated indentations can be formed causingleakage. DO NOT BY-PASS THE COALESCER unless the by-pass line is alsofiltered. DANGERFilter housings must be depressurized beforeperforming any maintenance activities, and depressurizationverified by a pressure gauge known to be in working order.!TROUBLESHOOTING CHART
