Pleated Filter Cartridges (ISO 2941 / ISO 16889 beta-rated) is specified where the duty calls for packing three to five times more filter area into the same housing with pleated stainless steel mesh cartridges, for higher flow, lower pressure drop and longer intervals between cleaning. The sections below cover the typical end-uses by industry, the mesh, micron and material decisions for each, installation practice, and the applications this product type is not suited to.
Typical Applications for Pleated Filter Cartridges
Where Pleated Filter Cartridges is specified and bought:
- Hydraulics & lubrication: high-pressure and return-line elements.
- Polymer & fiber: pleated melt filter candles.
- Gas & steam: process gas and clean steam filters.
- Water & coolant: high-flow strainer elements.
How to Specify Pleated Filter Cartridges for Your Application
- Pleat geometry: Pleat count and height set filter area; tighter pleats suit thinner media.
- Media: Woven stainless, dutch weave, sintered mesh or stainless fiber felt.
- Core & caps: Perforated support core and welded or bonded end caps rated for the differential pressure.
- Standard: Quote ISO 2941 / ISO 16889 beta-rated and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Handle by the end caps; pressing the pleats deforms them and opens bypass gaps.
- Back-flush or clean ultrasonically before the pressure drop reaches the collapse rating.
Common Selection Mistakes with Pleated Filter Cartridges
- Over-pleating stiff dutch cloth, which cracks at the pleat tips.
- Ignoring end-cap sealing, so fluid bypasses the media.
Where Pleated Filter Cartridges Is Not the Right Choice
Not for slurries with high solids that bridge between pleats — a cylindrical or basket element is easier to clean.
