Pleated Filter Cartridge FAQs
What is a Pleated Filter Cartridge?
A pleated filter cartridge is made by folding (pleating) the filter membrane to increase surface area and dirt-holding capacity. Compared to wound or melt-blown filters, pleated cartridges offer higher filtration efficiency, lower pressure drop, and longer service life for industrial water and process filtration.
What Are the Types of Pleated Filter Cartridges?
Pullner supplies multiple types of pleated filter cartridges based on media and application:
By Media Type:
- PP (Polypropylene) — general water/pre-filtration, chemical compatibility
- PES (Polyester) — high-temperature resistance
- PTFE — aggressive chemicals, solvents
- PVDF — high-purity, low extractables
- Nylon — high strength, chemical resistance
- Stainless Steel Mesh — reusable, cleanable
- Cellulose/Polyester — pool/spa applications
By Series:
- PPL, PPM, PPH — various PP pleated options
- HPPV — high dirt-holding nanofiber
- PHFZ — power plant boiler condensate
- WELPP, ELPP — electronic grade, low precipitation
- CMPA — CMP slurry filtration
- PLS — spa & swimming pool
Popular choices include 5 micron and 20 micron ratings for general sediment and process filtration.
Why Use a Pleated Filter Cartridge?
Pleated filter cartridges provide:
- Larger filtration area — pleated design increases surface area in the same cartridge size
- High dirt-holding capacity — gradient pore structure (in some models) traps more contaminants
- Multiple end-cap options — DOE, 222, 226 configurations to fit standard housings
- High retention efficiency — reliable particle removal and downstream equipment protection
- Long service life with low pressure drop — maintains performance throughout lifespan
- Wide chemical compatibility — depends on media choice (PP, PES, PTFE, PVDF, etc.)
- Cost-effective — reduces downstream filter replacement costs and frequency
- Easy replacement — standard sizes fit common housings
What Is the Structure of a Pleated Filter Cartridge?
A pleated filter cartridge consists of:
- End caps — available in multiple connection types (DOE, 222, 226) with spear, fin, or flat configurations
- Support core/skeleton — polypropylene or stainless steel for structural integrity
- Pleated filter membrane — PP, PES, PTFE, PVDF, Nylon, or other media depending on application
- Sealing O-rings — Viton, Silicone, EPDM, NBR, or Teflon based on chemical compatibility needs
Pleated cartridges are commonly installed upstream of RO membranes to protect downstream equipment and extend membrane life.
How Does a Pleated Filter Cartridge Work?
In most housings, the pleated cartridge is installed so flow runs from outside → inside. As fluid passes through the pleated media, particles are trapped on and within the filter surface. Clean fluid exits downstream through the core.
Replace the cartridge when differential pressure rises to your system’s replacement threshold (typically 2.1 bar for our cartridges) or when cleaning no longer restores acceptable performance.
What is the difference between pleated cartridge filter and string wound cartridge filter?
Pleated cartridges use folded membrane material to create a large surface area in a compact size, offering higher flow rates, better dirt-holding capacity, and longer service life.
String wound cartridges are made by winding yarn around a core. They typically have lower dirt-holding capacity and shorter life but can be more economical for applications with low particle loads.
For industrial liquid filtration with moderate-to-high dirt loads, pleated cartridges are generally the better choice.
What industries use pleated filter cartridges?
Pleated filter cartridges are used across multiple industries:
- Electronics — RO pre-filtration, deionized water, photoresist, CMP slurries
- Pharmaceutical — sterile solutions, vaccines, infusions, plasma
- Food & Beverage — mineral water, juice, beer, wine, dairy
- Chemical — organic solvents, inks, acids, bases
- Petrochemical — oilfield water injection, process liquids
- Power Plants — boiler condensate filtration
- Swimming Pools & Spas — polyester pleated cartridges for pool filtration
Our PHFZ, WELPP, ELPP, and CMPA series are designed for specific industrial applications.
We installed Pullner’s pleated filter cartridges in our condensate water system in Dubai. The dirt‑holding capacity and change‑out time were far superior to the previous filters. Excellent support and delivery too.
Published on: 2025‑10‑02
Using Pullner pleated water filters in our electronics‑grade water pre‑filter line. Performance is very consistent, minimal downtime, good value for cost. Would recommend to other plants in Turkey.
