New Bag-Sized Cartridges
Provide Up to 12 Times More Dirt-Holding Capacity

End-users requiring a solution for their frequent filter servicing problems now have an option. The new PL series bag-sized cartridge element from Rosedale Products, Inc. incorporates the advantages of both bag and cartridge type elements into a single, absolute-rated unit capable of handling up to 12 times more dirt over conventional bags before needing to be replaced.

Like bags, Rosedale’s bag-sized pleated cartridges are easy to handle and trap contaminants inside, preventing “wash off” during removal of spent or dirty cartridges. Like cartridge elements, they provide larger surface area and greater dirt-holding capacity than standard bags.


Rosedale’s bag-sized pleated cartridges are uniquely constructed to enhance durability and performance. Twenty-five* square feet of high-efficiency material is sandwiched between two flow-enhancing, coarse-mesh screens, and then pleated in a supported construction. This supported pleat construction ensures flow cannot be pinched off, and it also greatly strengthens the overall integrity of the element. The cartridge end caps, made of solid molded polypropylene, are thermo-bonded to the pleated cylinder.

*For size 2 cartridges. Size 1 cartridges have 13 square feet of material.


  • Eleven micron retention ratings, from 1 to 110 at 95 percent efficiency, are available
  • Three different top sealing ring designs – one to fit all needs
  • Available in standard bag sizes 1 and 2, to fit housings 8-15 and 8-30
  • Low-pressure drop




Like the company’s other filter elements, Rosedale’s PL series bag-sized pleated cartridge elements use polyester or polypropylene micro fibers and standard fibers to produce the high-efficiency filter media. This unique construction provides filtration to 1 micron at 95 percent efficiency: a real rating for the real world, consistently giving the same level of performance from batch to batch.

Greater Capacity Means Longer Life Filtration Level

Rosedale’s PL series bag-sized pleated cartridge elements have been tested with the Single-Pass Efficiency Test using water and the AC Fine Dust Test. Water is passed through an initial pre-filter (at 0.45 ╬╝), after which contaminant is injected into the water line. An automatic particle counter analyzes the number of particles per milliliter greater than a selected size, before the water enters the filter. The water then passes through the test filter, and the effluent is analyzed for the number of those same-size particles. The number of particles removed provides the efficiency rating. For example, if after the single pass, 95 percent of the particles are removed, then the filter is 95 percent efficient at the specified micron rating.

Filtration Efficiency

Using the Single-Pass Efficiency Test, Rosedale has determined the following efficiency ratings for their pleated cartridges. Real ratings are accurate and reliable, time and time again.

Disposable Bag-Sized Pleated Cartridges Provide High Performance at a Low Cost – Compatible with Models 8, LCO, NCO, and Multi-Bag Filters
