Using Pleated Media Cartridge TechnologyTo Optimize Dust Collector PerformanceBy Lee MorganCartridge dust and fume collectors are the most popularcollection systems for thermal spray operations today. Highefficiency cartridge collectors are compact; they operate atlow pressure drop; and they can be designed to produceemissions below the new OSHA limits for hexavalentchromium (Hex Cr) and other toxic metal dusts.However, many users of cartridge dust collectors mistakenlythink of the replaceable pleated filter cartridges ascommodity items. In point of fact, cartridges can varymarkedly in design and performance. Using the rightcartridges in your dust collector can ensure compliance withthe Hex Cr exposure limit of 5.0 micrograms per cubic meterand can also result in energy savings, reduced maintenance,and enhanced system reliability.Horizontal versus vertical cartridge mountingThe position in which a filter cartridge is mounted in thedust collector has a major impact on the effectiveness of thepleated media within. Sometimes filter cartridges aremounted on their sides. The biggest problem with horizontalmounting is that the dust does not get cleaned off the topof the filter, causing the dust to blind at least one third ofthe filter. This dust accumulation increases the air-to-mediaratio (which is determined by dividing the process airvolume by the filter's surface area) and can cause prematurefilter failure. One way to reduce this problem is to rotate theFigure 1 shows a top-loading problem in a horizontal filtersystem.filters monthly.In addition, because all of the incoming dust is dumped ontop of the filters, there is no chance for pre-separation ofheavy or abrasive particles from the air stream. Thissituation can shorten filter life or, in spark-generatingapplications, pose a fire hazard because any spark enteringthe collector will come into direct contact with filtercartridges. (Figure 1 shows a top loading problem in ahorizontal filter system.)The newest vertically mounted systems use a high, sideentry inlet that cross-flows the air into the dust collector atthe same height as the cartridges. The air is first sentthrough a series of staggered channel baffles that distributethe air while separating out larger particles and droppingthem straight into the hopper. This cross-flow effectcombines the benefit of a downflow-style air patternwithout turning the filters on their sides and wasting a largeportion of the pleated media.Pleated media selection factorsAn ultra-high efficiency, flame retardant media isrecommended for thermal spray operations. Polyester/siliconblended media with a melt-blown synthetic applied to thesurface will deliver up to MERV 16 efficiency, helping meetthe OSHA threshold for Hex Cr. This media also offers aSPRAYTIME Continues Industry NewsThe International Thermal Spray Association is pleasedto announce that it will continue to provide SPRAYTIMEfree-of-charge to the thermal spray community.

continued from page 2smooth surface for good dust release characteristics, facilitating cartridge cleaning.Use caution when comparing the media area (stated insquare feet or meters) contained in different filtercartridges. Although it is useful to compare the total mediaarea, it is actually more meaningful to know usable mediaarea. And do not rely solely on efficiency claims that arestated in percentages (e.g. 99.5% efficiency). OSHA limitsare measured not in percentages but in micrograms per cubicmeter, so you must make sure the amount of dust in the airis less than established limits. A reputable dust collectormanufacturer should provide a guarantee that emissions willbe below the allowable threshold.Advances in pleat configurationsA standard filter cartridge contains a pleated media packformed into a long cylinder and sealed at top and bottomwith end caps. In a typical cartridge, the inner section of thecylinder is essentially unused space, where a natural "cone"of dead air forms during operation. Through the years,manufacturers have sought ways to enhance cartridge dustholding capacity and service life.A recent solution has been the advent of internal conedesigns that turn the unused core of the cartridge intoadditional filtering space. An inner cone of pleated filtermedia adds 20-30% more usable media area to the cartridge.This extra filtration area reduces the air-to-media ratio sothat the media does not have to work as hard to filter thedust.On the standard cylindricaldesign (Figure 2, left), asignificant portion of thepulse energy is wasted inpulsing the bottom pan ofthe cartridge. With an innercone design (Figure 2,right), the cone does notuse any of the energy thatis normally used to clean the outer media pack: It simplymakes use of the energy that would have been wasted pulsing the bottom pan of the filter in conventional cartridgesystems. The result is lower pressure drop, which leads tofewer cleaning pulses. Both of these effects reduce energyconsumption and extend filter life. In addition, the reversepulse energy forces light dust particles directly into the hopper and out of the air stream, preventing dustre-entrainment.Pleat spacing and other design considerationsAnother important consideration is the actual spacing ofthe pleats in the filter cartridge.Since the inception of pleated dust collection cartridges inthe mid-1970s, a problem with their use has been properspacing and separation of the pleated media, to allow thedust that builds up in the pleats to be pulsed back off thefilter with a reverse blast of compressed air. Most cartridgesare made using either rotary or dimple-type pleaters thatcrease the media into an "S" shape, pinching off the bottomhalf of the pleat and thereby limiting its usability.INDUSTRYNEWS41 5 Ye a r A n n i ve r s a r y - SPRAYTIME Second Quarter 2007

Interviewing The Manipulator, The LanguageINDUSTRYFigure 3 above shows a close-up of cartridge mediaproduced in this manner. The pleating method used here,and the resulting tight compression of pleats in thecartridge, render much of the surface area unavailable forfiltering, allowing dust to remain trapped within the filtereven after pulse cleaning.A newer pleating technology makes use of hot meltseparators that open up the full length of the pleat,allowing the entire depth of the pleat to be utilized. Thisdesign allows significantly higher air flows per sq ft of mediathan what has been achieved in the past.Second in a Series from Plasma Powders and SystemsWhich manipulation system is best for your shop or specificapplication? Manipulation involves motion control andpositioning. Many manipulator configurations have beenused in thermal spray. A thermal spray manipulation“system” can be as simple as a fixed-speed turntable or ascomplex as two robots working together for the coatingprocess; one holding the part and the other the gun. Whatis available and what are the pros and cons of each? Thisquestion can be approached by “Interviewing” the differentcandidates that apply for the position of Manipulator.Before this though, it would be good to review theterminology, the dialog, of The Manipulator, especially whenrobots are considered. As with many technical specialties,the robotics industry has their own terminology. Terms thatare used include:*Absolute Encoder. Encoders are the electronic devices thatkeep tract of the position of each robot joint. Simpleencoders need to be “told where they are” each time thesystem is powered up. Absolute encoders retain knowledgeof their position, even when the system is turned off. Forsome systems, batteries are used with the encoders tosupply continual power for position records in order toconvert a standard encoder into an absolute encoder.Articulated. A term used for a robot consisting of segmentsheld together by joints, much like the human arm. Most offthe-shelf robots are of the articulated type.NEWSThe media pack in Figure 4 above shows an open pleatconfiguration. Virtually all the media surface is exposed tothe air stream, so the filter holds more dust betweencleaning pulses. The breathable design also reduces pressuredrop and improves dust release characteristics duringcleaning, using fewer pulses (and therefore, less energy).Tests have shown that open pleat cartridges, used incombination with HEPA safety filters, can achieve emissionlevels as low as .012 microgram per cubic meter on Hex Cr ensuring OSHA compliance and allowing recirculation of airdownstream of the collector for energy savings.For more information, contact Lee Morgan, president ofFarr Air Pollution Control, 3505 S.

Auxiliary Axis. Standard robots can also be provided with anadditional axis. For example, the robot supplier can provide arobot with an additional motor and associated control for usewith a turntable.Axis. This term is typically defined as the center around whichsomething rotates (syn: the axis of rotation). However, it hasbeen somewhat modified by the motion controls industry toinclude linear motion (“A linear axis”). For example, a five-axisrobot mounted to a slide with position control is considered asix-axis robot. In addition, in this industry, the term is usuallyapplied only to positioning devices. A rotary turntable withoutposition control is not considered an axis.Cartesian Robot or Gantry Robot. Unlike the articulatedrobot, a slide is used for each axis of the robot.Degrees of Freedom. This term is used in place of axis. A fiveaxis robot is also stated as having five degrees of freedom.End-effecter. Also called end-or-arm tooling. For the thermalspray industry, this is often the gun but, when the part is heldand moved by the robot, this is the device that holds the partwhile it is being sprayed.Payload. This is the total weight (including fixture, hoses andcables) that can be mounted to the end of the robot withoutdegrading the performance of the robot (operating within thespecified levels of acceleration).Reach. This is the maximum distance from the first axis of therobot to the end of its tool mounting plate. It is importantwhen evaluating the area that can be sprayed.Robot. This is a machine that can be programmed to performmotions with at least three axes. (An elevator is not a robot)Wrist. This is usually the next-to-the-last axis of the robot.The motion is like the motion of your wrist. The last axis isusually pure rotation, like spinning the dial on a wall safe.(Next, considering the various applicants for The Manipulator.)For a comprehensive glossary list, go towww.robots.com/glossary.htm.For more information, contact series author, Dale Moody viaemail dalermoody@aol.com(The first article appeared in SPRAYTIME second quarter 2007 issue.)Technical Program Open To PublicNext Program in HawaiiThe International Thermal Spray Association welcomesnon-member participation at the Technical Program portionof their membership meetings.

NCS Bonds with StrongholdThe joint research and development projects betweenNation Coating Systems (NCS) and Stronghold Coatings hasstarted to grow into several large projects. The completionof the Met Lab at NCS has given Stronghold the ability toreview coatings and make modifications for variousapplications. The actual projects have grown from nanoparticle applications to new improved sealers for thermalsprayed coatings.One major project is with RNT, which was covered in anarticle in the American Welding Society magazine on a newmaterial, that will enable soldering and brazing without atorch. NCS is making the development parts for RNT for trials of their material on various parent materials for all typesof applications. Stronghold has been doing trials anddevelopment of which coating process will give the highestbond strength with the lowest cost.Another major application project is utilization of Dichtolas a sealer for testing with the Navy Research Lab. Thiscoating has passed several tests and is now being looked atby several major organizations. The coating is being lookedat for many types of applications and some information isnot open for publication. Stronghold along with NCS hasmade several improvements in the application such asremoval of a former HAPS material (xylene) which is now nolonger used. The newest work being done with Dichtol isremoval of just about all of the VOCs in the solvent system.This is still under trial and no samples are ready for testinguntil Stronghold has finished its homework.The new material Liquid Mask, which is being used byseveral thermal spray shops, is almost ready for a majorchange. Stronghold is now testing a new version of Liquidmask which has no solvents. Many shops liked the newmasking material when it first came out but the solventcontent made it not a material that they wanted to use. Thenew version will soon be ready for testing by customers anda notice will be sent out for possible shops that areinterested. NCS is the current test site and with a few modifications it will meet their application requirements.The above are some of the joint projects performed by thetwo companies. Applications vary from commercial to military. If every thing goes right development will start for amajor aircraft engine manufacturer. Doing development foractual applications and not for just test or a paper has paidoff for the both companies.For more information, contact Larry F Grimenstein, NationCoating Systems, Inc., email: ncslgrimen@aol.com or visitwebsite www.nationcoatingsystems.comW H E R E I S YO U R A RT I C L E ?You and your company have the opportunity to helpdesign the content of your thermal spray communitynewsletter.The SPRAYTIME Editorial Staffencourages and welcomes your contribution.Send news and articles via email tospraytime@thermalspray.orgINDUSTRYNEWS101 5 Ye a r A n n i ve r s a r y - SPRAYTIME Third Quarter 2007
