PP cartridge filter is a widely‑used industrial filter consumable made of pure polypropylene material, covering melt‑blown and pleated construction options for diverse liquid filtration demands. This pp cartridge filter effectively removes sediment, rust particles, suspended solids and colloidal impurities from process water, acting as reliable pre‑filtration protection for RO, NF and UF membrane systems. With excellent chemical resistance against most neutral and weak corrosive fluids, it fits food‑beverage, chemical processing and municipal water applications. Thermal‑bonded structure without adhesive prevents secondary liquid contamination. Our full‑range pp cartridge filter can directly replace most mainstream brand filter elements. Many industrial customers match RTM41HF050E filter cartridge and HFU660CAS010JUW filter element with pp cartridge filter to set up multi‑stage purification solutions for different industries.

Product Overview
PP cartridge filter is one of the most common filter elements for industrial liquid filtration. It mainly includes two mainstream types: polypropylene melt‑blown filter cartridge and polypropylene pleated filter cartridge. Melt‑blown pp cartridge filter features gradient depth‑filtration structure with low cost, while pleated pp cartridge filter owns larger effective filtration area, higher flow rate and greater dirt‑holding capacity. Available in multiple lengths from 10‑inch to 60‑inch, micron ratings range from 1 μm up to 100 μm. With DOE, 222, 226 end cap options, pp cartridge filter can be installed into standard filter housings for raw water pre‑treatment, process liquid polishing and particle removal.
PP cartridge filter undertakes key particle‑removal tasks inside water treatment systems. It reduces water turbidity and intercepts most solid contaminants before water flows into membranes and precision equipment, greatly lowering the risk of membrane fouling. Though imported pp cartridge filter delivers stable performance, high unit cost and long lead‑time increase operating expenses for global buyers. As a professional filter manufacturer, our pp cartridge filter strictly controls raw‑material quality and dimensional tolerance. Every batch undergoes necessary inspections before shipment to guarantee consistent filtration performance for end‑users and system integrators worldwide.
Core specifications of PP Cartridge Filter: Filter media: pure polypropylene; types: melt‑blown / pleated; micron rating:1‑100 μm; common lengths:10/20/30/40/60 inch; end cap: DOE / 222 / 226; connection: inner core / open end; manufacturing: thermal bonded, no adhesive; O‑ring: silicone, EPR, NBR optional; max continuous working temperature:60℃; recommended replacement differential pressure:2.4 bar; compatible with standard industrial filter housings.
Replacement pp cartridge filter supports direct drop‑in installation without housing modification. Thanks to good chemical compatibility, abundant specification selection and cost‑effective performance, it is the preferred consumable for general industrial water treatment and liquid polishing filtration.
Filtration Working Principle
PP cartridge filter adopts depth filtration principle. For melt‑blown pp cartridge filter, polypropylene fibers form gradient porous structure from outer layer to inner core; large particles are trapped on outer layers while fine particles are captured inside fiber gaps. For pleated pp cartridge filter, liquid passes through folded polypropylene media, impurities are intercepted on media surface and inner depth layers. The whole filter element is thermal‑bonded without glue, eliminating organic substance dissolution risk. When inlet‑outlet differential pressure reaches 2.4 bar, pp cartridge filter reaches dirt‑holding saturation and shall be replaced timely to maintain stable effluent quality.
Core Competitive Advantages

FAQ
Q1: What is PP cartridge filter used for?
A1: PP cartridge filter is polypropylene filter element, mainly used to remove suspended solids, sediment and particle impurities in liquid for industrial water pre‑treatment and process liquid polishing.
Q2: What is the difference between melt‑blown and pleated PP cartridge filter?
A2: Melt‑blown PP filter is low‑cost depth filter; pleated PP filter owns larger filtration area, higher flow rate and longer service cycle under same dimension.
Q3: When to replace PP cartridge filter?
A3: Replace when inlet‑outlet differential pressure reaches 2.4 bar. High‑turbidity incoming liquid will shorten service life.
Q4: Can PP cartridge filter be cleaned and reused?
A4: Melt‑blown PP cartridge filter cannot be regenerated. Pleated PP filter can be simply rinsed for short‑term emergency use, yet back‑washing cannot fully restore original performance, disposable replacement is recommended.
Q5: What parameters are needed for selecting PP cartridge filter?
A5: Please confirm filter type, micron rating, length, end‑cap style, working temperature and medium chemical property, or provide original part number for quick matching.
