1 1 APPLICATIONPROFILEF ilters for Compressed Air DryersThe ProcessClean, dry Compressed air plays an essential role in industry withmany applications, and is often considered a "fourth utility" atmost facilities. It is used to move conveyors, transport products,power pneumatic tools, automate equipment, operate criticalinstrumentation, packaging, and for process Compressed air drying process includes many equipmentcomponents including Filters . Their performance has an affect onthe degree of dryness and cleanliness of the Compressed air. Compressor:Atmospheric air is Compressed to a desireddischarge pressure level for downstream use.

2 Aftercooler:Water or air cooled heat exchanger cools thehigh temperature of the air resulting from the heat ofcompression. A significant amount of entrained moisturecondenses into liquids. Separator:Uses centrifugal action, vanes, baffles, or wiremesh pads to remove entrained liquids that are condensed bythe aftercooler. Prefilter: A coalescer designed to remove fine oil and watermist aerosols still remaining to prevent the fouling of thedesiccant bed in the dryer . Common prefilter ratings are to1 micron. dryer :Desiccant or refrigerated Dryers are common designsto remove the remaining water vapor from Compressed air.

3 Adual tower desiccant dryer provides the most effective moisturereduction. Dryness is achieved by dew point suppression andreduces further potential for moisture condensation indownstream piping. Afterfilter:A particulate filter to remove desiccant dust thatmay carry over from the dryer . Usually rated for 1 to 3micron particulates removal. Receiver: Provides storage capacity to meet peak airdemand and dampen compressor pulsations. The ProblemCompressed Air Quality. A major problem in Compressed airsystems is the presence of water, oil, and solid contaminantswhich can adversely affect air quality and lead to rust, scaling,instruments clogging, valves sticking, frozen lines, and processcontamination.

4 Water vapor is naturally present in air andcondenses as it is Compressed and cooled. Oils are introducedby lubricated air compressors. Solid particles can be in the formof scale, rust, desiccant from a dryer , and atmospheric dust froma compressor intake. Four Compressed air quality levels exist which are defined byapplication. Most industrial applications use one of the first three Level Application Plant AirPneumatic tools, general plant air uses Instrument Air Painting, coating, control instrumentsProcess AirIndustrial, food, pharmaceutical, electronics Breathing AirHospitals, diving tanks, quality level is often affected by two criteria; the dryness levelrequired and contaminant removal allowed by end useapplications.

5 Dryness:The dryer type can affect the dryness level. Twintower desiccant Dryers are most common for water vaporremoval with industrial applications because they are rated ata pressure dewpoint of 40F. Activated alumina, silica gel, ormolecular sieve are common desiccants used for water vaporadsorption. Contaminant Removal: A prefilter and afterfilter play avital role in removing condensate, oil lubricants, and & Water:A coalescer is used as a prefilter to removeoil and water aerosols to prevent fouling of a dryer sdesiccant bed. A prefilter is installed upstream of adesiccant dryer to protect it, enhance its effectiveness,and increase its life.

6 Desiccant Dust: As a desiccant dryer cycles betweendrying and regeneration, desiccant "fines" can be carriedover. An afterfilter is installed downstream of a desiccantdryer to remove this dust and to prevent plugging of valves,regulators, instruments, and potential FILTERSOLUTIONF ilters For Compressed Air DryersAGS Series Coalescer/PrefilterCP Series AfterfiltersHow it Works:The Consler brand AGS Series is a coalescer located upstream of the dryerand works as a prefilter to protect the dryer s desiccant bed from fouling byremoving oil and water aerosols.

7 Compressed air enters the housing,flowing from the inside of the coalescing element outwards. Oil or wateraerosols enter the element interior, are intercepted by a microglass filtermedia, extracted from the air, and agglomerate into increasingly largerdroplets as they are driven to the outside of the cartridge by the velocity ofthe air. These larger droplets once formed, drain off the element exteriorand fall by gravity into the housing : Coalescing elements rated for removal of oil and water aerosols and solidparticles, micron and up at a 99% minimum removal efficiency.

8 Mostdryer systems will typically require a prefilter be rated for to 1 micron. Utilizes a pleated, multilayered microglass coalescing media to offer morefilter surface area and a longer life. Offers a lower pressure drop. Most prefilters are sized for an initial cleanpressure drop of less than 1 psid. Housing design pressure ratings from 150 to 5000 psig. Housing connection sizes from 1/2" to 24".How it Works:The Consler brand CP Series is a solids particulate removal filter designedto provide positive protection of sensitive downstream controls, meters,regulators, and valves by removing desiccant dust carried over from thedryer.

9 The gas stream enters the housing and flows from the outside of theelement inwards with solid particles being intercepted on the filter element : Filtration of desiccant dust particles from to 25 micron. The mostcommon afterfilter rating being specified for dryer systems is usually 1 to3 microns. Pleated, "radial fin" filter elements with high surface area for longerservice life and higher dust holding capacity. Utilizes a replaceable, cleanable, and reusable filter element. Mostdesigns employ a single element. Offers a very low pressure drop. Most afterfilters are sized for an initialclean pressure drop of to 1 psid.

10 Many filter media options including polyester, polypropylene, cotton,fiberglass, Nomex, and paper. Polyester is frequently used forcompressed air up to 300 F. Fiberglass is common for highertemperatures up to 700 F. Housing design pressure ratings from 150 to 5000 psig. Inline housing connection sizes from 1/2" to 24".ISSUEGTX-224 Graver Technologies designs, engineers and manufactures Consler brand filtration products
