MESSER DUST COLLECTORSModels 2-8 through 4-128 Messer collectors are designed for extra-fine particulate generated inoxyfuel, laser and plasma cutting applications.Messer filters feature MERV 15 Ultra-Web filters with Donaldsonnanofiber technology.Configurable systems are available with fans, control panels and dustdisposal systems to meet your exact needs.Service centers throughout North America.

MESSER CUTTING SYSTEMS, INC.DONALDSON COMPANY, INC.CARTRIDGE FILTER TECHNOLOGYULTRA-WEB NANOFIBER FILTER MEDIADonaldson leverages almost 100 years of air filtration experience in the development of filtration media,providing tremendous value to our customers. Ultra-Web media incorporates a durable layer of premiumnanofiber designed to intercept the smallest dust particles at the surface of the media.Independent laboratory testing determined that Ultra-Web media has a Minimum Efficiency ReportingValue (MERV) of 15 based on the ASHRAE 52.2-2007 test standard. Ultra-Web media rated MERV15 is themost optimized, balanced and cost-effective media in the marketplace, providing higher efficiency withoutcompromising pressure drop or filter life. For more information on Ultra-Web and MERV ratings,please visit www.ultrawebisalwaysbetter.com.10 micron10 micronNanofiber Media(600x)Nanofiber surface loading technology is availablein all Ultra-Web and Fibra-Web cartridge filters.Commodity Filter Media(600x)Conventional media has spaces of up to 60 µm betweenfibers, allowing dust to become deeply embedded.SYSTEM ENERGY EFFICIENCY, SAVINGSAND NOISE CONTROLSurface loading is a key characteristic of Donaldson's Ultra-Web media. This surface loading capabilityimproves the effectiveness of pulse cleaning, which minimizes system pressure differential, thereby conservingcompressed air usage and brake horsepower requirements of the system fan.Clean Ultra-Web FilterSurface-Loaded Ultra-Web Filter(substrate still clean)Ultra-Web nanofiber media is loaded with ISO fine dust. Dust particles collect on the surface of the media and clean off easily while the substratestays clean. A depth-loading filter would allow dust particles to penetrate deeply into the substrate where they build up and choke off the airflow.

MESSER CUTTING SYSTEMSSYSTEMS, INC.DONALDSON COMPANY, INC.KNOW YOUR CUTTING DUSTSThe U.S. Occupational Safety and Health Administration (OSHA) has issued a National Emphasis Programand continues to communicate with most industries on the hazards of combustible dust. The agency'sfocused effort is targeted at reducing combustible dust risks in industrial plant settings. Is your planteffectively managing the risks associated with combustible dust in its processes?For decades Donaldson Torit has been providing quality dust collectors that have become an integral part ofmany plant’s combustible dust compliance strategies. Donaldson remains active in supplying dust collectorsto support your combustible dust control strategy by interfacing with you and your experts on fire andexplosion protection equipment and strategies.These pages are intended to increase your understanding of typical combustible dust management strategiesand some of the components involved.WHERE TO START?A Messer representative can review your operational challenges to help you better understand how to integrate dustcollection into your combustible dust management strategy.

MESSER CUTTING SYSTEMS, INC.As a manufacturer and supplier of Industrial Filtration Products,Donaldson can assist process owners/operators in the selectionof filtration technologies.Compliance with applicable codes and standards remains theresponsibility of the process owner/operator. Among otherconsiderations, the current National Fire Protection Association(NFPA) standards require owners/operators whose processesinvolve potentially combustible materials to have a currentHazard Analysis, which can serve as the foundation for theprocess owners/operators hazard mitigation strategies.Upon request, Messer can assist owners/operators toincorporate Donaldson Filtration Product into a comprehensivefire and/or explosion mitigation strategy. Messer requirescomplete and accurate information on all potentiallycombustible contaminants and fire and/or explosion mitigationstrategies that process owners/operators intend to pursue.Visit www.nfpa.org for more information.STANDARDS, CODES, ANDGUIDELINES THAT IMPACT DUSTCOLLECTOR DECISIONSMany standards and codes may influence your decisions ondust control, including local, state and federal regulations.Knowing the codes that apply to your facility is critical, andwe recommend research of code requirements in your area.A few commonly referenced standards for combustible dustrisk management strategies include those issued by: NFPA,the International Mechanical Code, the International Fire Code,Factory Mutual Property Loss, and OSHA (federal).Since each Authority Having Jurisdiction may have a specificset of codes it references, you should have general knowledgeof more than one standard or code. Standards are published byNFPA, including both design and operational standards focusedon combustible dust (see above).FIRE TRIANGLEFire management strategies traditionallyfocus on the control or elimination ofone of the three key elements necessaryfor a fire — often represented by the“fire triangle." Managing one or moreof the elements in the triangle candecrease the fire risk.EXPLOSIONPENTAGONExplosion risk management strategiesconsider a slightly expanded set ofelements often represented as an“explosion pentagon.” In addition tothe key elements from the fire triangle —fuel, heat and oxygen.The explosionpentagon includes two additionalelements necessary for an explosion:“Dispersion of Dust” and “Confinementof Dust.” As with fire managementstrategies, the management or removalof one or more of the elements in theexplosion pentagon can reducethe explosion risk. While many explosionmanagement strategies focus oncontrolling the same elements in thefire triangle, explosion risk managementstrategies that focus on the dispersionof dust, or the containment of dust alone,may require a separate strategy toaddress any remaining fire risks.IGIRGYXOIONRS TPESDIS F DUOSince these standards are often cited by OSHA and havebeen adopted as code in many areas of the country, they area good starting point for developing your combustible dustmanagement strategy.NE/ANITIO[H NE SOAT U]RCDUSTEXPLOSIONECONFIOF NEMDU ENTSTCOMBUSTIBLE DUST STATEMENTDONALDSON COMPANY, INC.COMBUSTIBLEDUST/FUME[FUEL]To be compliant with OSHA regulations, you must meet other requirements and all applicable standards or codes.Visit www.osha.gov to find OSHA regulations.
