Pleated Filter Technology
Pleated filters are widely used as effective surface filtration due to their excellent flow rates and high efficiency.
Pleating significantly increases filtration surface area while maintaining high dirt-holding capacity and low pressure drop. The multilayer construction of many pleated media also provides depth filtration, enhancing particle retention and classification.
Premier Pleat Construction
Pleated is superior for high-flow surface filtration and consistent particle removal.
Rigid inner core and polypropylene outer cage protect the pleat pack, prevent bypass, and support thermal bonding of various end-caps. The redesigned cage increases void volume by over 10%, improving flow distribution, reducing pressure drop, and maximizing dirt-holding capacity.
How to Select Right Pleated Filter Cartridge
By 4 Steps:
- Remove suspended solids?
- Protect downstream equipment?
- Improve product clarity?
- Meet quality or regulatory specifications?
Micron ratings indicate the size of particles a filter can capture, measured in micrometers (µm). Ratings typically range from 0.1 µm to 1000 µm, and the lower the number, the finer the particles the filter removes.
Your fluid type usually guides media selection. Polypropylene and polyester are the most widely used options for pleated filters.
Common cartridge lengths are 5, 10, 20, and 30 inches. Longer cartridges typically provide higher dirt-holding capacity and flow rates.

Common Pleated Filter Cartridge Issues
Chemical Compatibility Failure
Filter media or seals may degrade due to chemical incompatibility or excessive temperatures.
Shorten expiration date
Can result from high contaminant loading, chemical attack, or unsuitable operating conditions.
Inconsistent Filtration Performance
Can result from unsuitable media, bypass leakage, or damaged filter cartridges.
Rapid Differential Pressure Rise
High solids loading, unsuitable media, or an undersized filtration system.
Cartridge Collapse or Deformation
May result from excessive differential pressure, high temperature, or improper installation.
Improper End Cap or Seal
May cause leakage, bypass, poor housing fit, or system failure.
Frequently Asked Questions
What is a pleated filter cartridge?
A pleated filter cartridge is a filtration element made from folded filter media that increases surface area within a compact design. It provides efficient particle removal, high dirt-holding capacity, and low pressure drop.
Which filter media should I choose?
Choose filter media based on fluid type, particle characteristics, micron rating, chemical compatibility, operating temperature, and pressure. Common options include polypropylene, polyester, nylon, PTFE, and PES membranes for different industrial applications.
What micron rating should I choose?
Select a micron rating according to the particle size you need to remove and the required filtration efficiency. Common ratings range from 0.1 to 100 microns, depending on the filter media and application.
Lab equipment, on the other hand, refers to the instruments and apparatus used for various laboratory procedures and experiments, such as microscopes, centrifuges, balances, and spectrophotometers. Unlike consumables, lab equipment is generally reusable and is used to facilitate a wide range of experiments or analyses.
What is a pleated filter cartridge used for?
Pleated filter cartridges are used to remove suspended particles and contaminants from liquids or gases in applications such as water treatment, food and beverage processing, pharmaceuticals, chemical production, and microelectronics manufacturing.
What cartridge lengths are available?
Pleated filter cartridges commonly come in 5-inch, 10-inch, 20-inch, and 30-inch lengths, with some manufacturers offering 40-inch options. The appropriate length depends on housing compatibility, required flow rate, and filtration capacity.
How do I choose a pleated filter cartridge material?
Choose cartridge materials based on chemical compatibility, fluid composition, temperature, operating pressure, and regulatory requirements. Ensure the filter media, support layers, end caps, core, and seals are compatible with the process fluid.
What is the difference between depth and membrane filters?
Depth filters capture particles throughout a thick, porous media structure, often providing high dirt-holding capacity. Membrane filters use a defined porous barrier for more precise particle retention and are commonly selected for critical filtration applications.
How often should pleated cartridges be replaced?
Some pleated cartridges can be cleaned and reused if their materials and construction support the cleaning process. However, reuse depends on the manufacturer’s instructions, contaminant type, chemical exposure, and whether filtration integrity can be maintained.
What are DOE, 222 and 226 end caps?
DOE (Double Open End) cartridges have open ends for compatible housing connections. 222 and 226 end caps feature different bayonet-style fittings and sealing arrangements, helping secure cartridges and prevent fluid bypass in compatible filter housings.
Are pleated cartridges reusable?
Some pleated cartridges can be cleaned and reused if their materials and construction support the cleaning process. However, reuse depends on the manufacturer’s instructions, contaminant type, chemical exposure, and whether filtration integrity can be maintained.
