  1. Cartridge Filter Media

    Leave a Comment

    Selecting the right filter media for your cartridge dust collector plays an important role in keeping your system running at peak performance. You want to ensure the filter media you choose is best for your unique application and specific needs. Choosing the incorrect cartridge filter media can negatively impact the life of your filter, escalate energy usage, and increase the risk of dust build-up resulting in a dangerous dust collector explosion.

    Most Common Cartridge Filter Medias

    For a majority of cartridge dust collector applications, about 90% can be handled with just one of these common types of filter media. There are other specialty media’s that can help with unique environmental conditions, but it is rare and can cost two to three times as much as Spunbond polyester filters.

    80/20 Cartridge Filter Media

    80/20 filter media is comprised of 80% cellulose and 20% polyester. It is one of the most common and lowest priced filter media available for basic applications. This mixed filter media will provide more strength than a 100% cellulose cartridge filter.

    Industry UseTreatmentsBenefits
    Blasting, Paint Booths, General Dust FiltrationFire retardant (FR): can be added to help keep flame from bursting; doesn’t increase temperature resistance, Anti-StaticLowest price, widely available commodity filter for basic applications

    Nanofiber Cartridge Filter Media

    Nanofiber comprises of a thin, synthetic web of fibers that is overlaid on top of a substrate, usually 80/20 but sometimes polyester. This works similar to a PTFE membrane on a filter bag; the web of fibers will act as a dust cake and capture a bulk of the dust particulate. One of the other features of Nanofiber is that in comparison to 80/20 filter media, nanofiber can withstand greater cleaning demands.

    Industry UseAvailable TreatmentsBenefits
    Plasma cutting, Metalworking, Castings, Smoke or very fine dustFire retardantBetter at handling superfine dust versus 80/20

    Spunbond Polyester Cartridge Filter Media

    Spunbond polyester performs well in applications with heat, or abrasive dusts. This option is ideal for applications that require a strong filter media with enhanced dust release.

    Industry UseTreatmentsBenefits
    Cement, Cardboard, Sandblasting, Abrasive BlastingFire retardant, PTFE, Hydro-Oleophobic, Anti-staticHigh burst strength, increased dimensional stability

    Polyester Cartridge Filter Media

    Polyester is rigid and contains additional pleats, making it more permeable and allowing an easier flow of air.

    Cement, Cardboard, Sandblasting, Abrasive BlastingFire retardant, PTFE, Hydro-Oleophobic, Anti-staticHigh burst strength, increased dimensional stability

  2. Cartridge Filter Construction

    1 Comment

    Cartridge FiltersCartridge dust collectors are designed to be modular and compact while engineered to capture fine dust particulate. Common applications include metalworking and castings, powder coating, rubber manufacturing, bulk powder processing and more. This type of dust collection system requires cartridge filters. The right cartridge filter for your system will be dependent on your dust collector’s design and application. Below we are exploring some of the most common construction options for cartridge filters.

    Cartridge Filter Construction

    Top ConstructionBottom ConstructionOuter ConstructionFrame or Top MaterialShape
    OpenOpenOuter Bands: Commonly made out of nylon and used to hold pleats in place.Polycore (hard plastic)Round – Most common. Standard cartridge filter diameter sizes for this shape are 12.75”, 13.8”, and 13.9”.
    FlangeClosedExpanded Metal: A sheet of metal perforated with dashes which are off set, and then stretched out or expanded over the pleats. The same metal frame can be added to the inside of the cartridge. This construction can be referred to as inner and/or outer expanded.Galvanized Metal – Most common Oval
    Closed with Bolt HoleNone: The outer construction can also have neither a band nor frame.Stainless Steel – Least common, most expensiveConical

    Cartridge Filter Media

    • 80/20: Constructed of 80% cellulose, 20% polyester which provides more strength to the cartridge filter than 100% cellulose.
    • Nanofiber: A thin, synthetic web of fibers which is overlaid on top of a substrate, usually 80/20 but sometimes polyester.
    • Spunbond Polyester
    • Polyester
    • Specialty Medias: Aramid is one example of rare cartridge filter media. This specialty media can cost up to 2-3 times more than Nanofiber or Spunbond.

    When it comes down to choosing the right filter media, it may not be as tough as you think. 

    Do you know the characteristics of the dust you will be filtering?  If you do, then you’re a step ahead of the game. 

    There are three common medias for filter cartridges and they can cover a wide variety of applications. If you know your dust characteristics then watch our short video guide that provides a brief introduction and understanding into cartridge media, and which one may be best for your application.


    Video Transcript:

    Hi this is Bob from US Air Filtration and today we’re going to talk about cartridge filter media’s.

    While there’s a lot of different media’s out there, most applications, probably over 90% of them, can be handled with one of three common medias. We’re gonna take a look at those today.

    I have here a couple of standard filters. This one is made from a media called 80/20. 80/20 gets its name from being 80% cellulose and 20% polyester which is mixed in to give it some strength. But it looks and feels a lot like paper and the paper is folded into pleats and packed into this cartridge.

    This is what a swatch of the media looks like before it’s been put into the cartridge. This filter is a great general use filter for blasting or paint boosts and just general dust filtration.

    The next filter I want to show you is one made with a media called nanofiber. Now you look at these two filters they look almost identical. Actually when you look at the media, the media looks identical, and that’s because nanofiber is made by taking the same 80/20 substrate and putting a microscopic web of fibers over the paper.

    So when you look at them next to each other they look identical, but the Nanofiber is much better at handling the superfine dust particulate.

    So when you have plasma cutting or smoke or really fine dust, nanofiber is going to be the better choice for you because those little fibers capture the dust and keep them from plugging up the filter.

    You can use nanofiber as a general use filter as well. Some people say it lasts longer than the standard 80/20 because of that layer of nanofiber on the top of it.

    The third filter I want to show you (or filter media) is this one which is made from spunbond polyester.

    You’ll notice that the pleats are not as packed in this filter and that’s because this media is a little more permeable. This is a very tough rigid plastic feeling filter media.

    This is what the spunbond polyester looks like a close. This is filter is one you that you want to use when you’re trying to avoid damage to the filter because you’ve got tough dust. So this is used often in cement industries, cardboard, abrasive blasting, sandblasting or anything else where strength is required. Spunbond polyester is the filter media of choice.

    You can also add a PTFE membrane to spunbond polyester that you can’t to these other filters. So when you have a real sticky dust, putting the membrane on spunbond polyester may also be an option for you. There are also other specialty media’s to help take care of unique environmental conditions. To find out which filter media is right for you call and talk to one of our experts.
