120 ® H I G H C A P A C I T Y F I L T E R B A G S Rosedale has a wide selection of filter media available to help solve your filtration problems. Our product offerings include filter bags, filter cartridges, and perforated strainer baskets. This selection features a variety of options from low-cost, disposable filter media; through high-performance filter cartridge; to cleanable stainless steel elements. The filtration efficiency values specified in our data (see Element Performance Chart on page 123), are the indication of the filter's performance. Unlike many manufacturers, Rosedale publishes the filtration efficiency and dirt capacity of our media, providing all the information needed for an accurate sizing of a filter. Our media is offered in standard grades and high efficiency. Standard grade refers to products which are nominally rated. This means there is no specified efficiency at the Rosedale Filter Media micron size but the product is interchangeable with industry standards. Rosedale high efficiency filter media is rated 95%, 99%, or 99.98% efficient at the specified micron level. Bag or cartridge filters are usually selected so that the clean pressure drop does not exceed 2 psi. Change-out is recommended at 15 psid (for bags), and 30 psid (for cartridges).

Performance Problems?Not with Rosedale’s filter elements!
Rosedale offers different levels offiltration to meet different needs, suchas low-cost, standard efficiency bags, upto high-efficiency, high-capacity elements.Our standard capacity elements usuallyhave about 4.4 square feet of surfacearea, holding approximately a poundof contaminant, perfect for manyapplications. The bags we offer for thislevel of filtration include our standard bag,the Beta Bag®, and our new Locktopplastic top, self-sealing bag. These bagsfit our standard side inlet housing, which,coupled with bag technology, offers easeof use, storage, and change out.

Still Not Enough?Don’t worry, we’ve got moresurface area
If you have contaminants in your system,Rosedale has the solution. Typically theseunique filter bag has from 5 to 25 squarefeet of surface area, and holds from 1 to 11pounds of contaminant. Offers greatbalance between cost and capacity. Filterelements in this grade of filtration includeseveral bags featuring our unique designs.The new X-Tend bag, the Surface Plus bag,the Graded Density bag, and our bag-sizedPleated Cartridge. All will fit our standardhousings, and offer features that Rosedaleis famous for, such as keeping costs downand keeping contaminants inside the bag.
Size Doesn’t Matter...But surface area does!!!
If you require ultrahigh capacity filtrationand efficiency, nothing beats our Platinumseries of filter elements. They use between85 and 600 square feet of surface area tofilter out anywhere from 8 to 600 poundsof contaminant. At efficiencies as highas 99.98 at a beta rating of 5000. Imaginechanging your filter element just once everysix months. It’s possible with Rosedale’sPlatinum Elements!!! The 500 series, 700series and 900 series of Platinum elementsare large multi-surface, pleated filters,constructed like cartridges. Different Seriesfit into different Rosedale housings, butall can be accommodated in one of ourstandard style housings, offering fantasticfiltration options.

Use this chart to determine the filter performance you require. The Product Groups are listed on the left,Micron Sizes are in (red), with corresponding Efficiency (blue) and Beta Rating (green) along the top.
* Range of flow varies with micron selection - consult individual product group flow curves. ** Dirt capacity is based on minimum flow using AC Fine, AC Coarse, or Composite Test Dust.

Bag-Sized Pleated CartridgesInnovative design combinesthe advantages of bags withthe best features of cartridges.Like bags, contaminant istrapped inside, and they’reeasy to handle. Pleatedconstruction, like a cartridge,packs more surface area inless cubic space. Rated 1-110microns at 95% efficiency.See page 139.
SurfaceplusFilter BagsThese filter bags are forheavy dirt load applications.With 3 times the surfacearea of similar sized bags, itwill increase the amount ofcontaminant held, andextend the time betweenchange-out. Rated 35-110microns at 95% efficiency.See page 137.
Standard BagsHigh-capacity filter bagswith ratings to 1 micronare available in a widerange of sizes and materialsfor general use. Special-purpose bags for high-temperature service and oilremoval are also available.See page 126.
Graded Density Bags(Membrane Prefilters)Great dirt-carrying capacityis combined with fine filtrationefficiency in these multilayerbags. These bags are excel-lent prefilters in applicationspreviously requiring cartrid-ges, cutting costs. Rated 1-19microns at 95% efficiency.See page 134.
Beta BagsThese bags meet the moreexacting requirements of fineprocess filtration and hy-draulic and lubricating fluidfiltration. They’re rated bythe multi-pass method offilter performance evalua-tion, allowing direct com-parison between Beta bagsand cartridges. Rated 8-47microns at 98.7% efficiency.See page 131.
All-Polypropylene BagsThese bags have a plasticcollar sonically welded intotheir opening. This collarhas integral handles asstandard feature. The bagsare sewn, then turnedinside out to preventleakage through thethreads. Rated 1-110microns at 95% efficiency.See page 129.
