Water Filtration PP Pleated Filter is a widely‑used all‑polypropylene pleated filter cartridge for industrial liquid clarification and water pretreatment. Adopting hot‑melt adhesive‑free pleated polypropylene media, it delivers large filtration area, low pressure drop and broad chemical compatibility, covering micron ratings from 0.1 μm‑100 μm. These pleated pp filter elements are commonly installed inside standard filter housings for RO pre‑filtration, food‑beverage, chemical and electronics water treatment. Our replacement pp pleated water filters support multiple end‑cap options including DOE, 222 and 226, enabling direct drop‑in interchange with most mainstream brand filter housings. Many water‑treatment projects combine 3M HF40PP001A01 filter cartridge and RTM41HF050E filter element with pp pleated filters to build multi‑stage water purification systems for removing sediment, rust and colloidal impurities.

Product Overview
Water Filtration PP Pleated Filter cartridge is constructed of 100% polypropylene materials, including pleated pp filter media, support layers, inner core and end caps, all assembled by thermal‑fusion bonding without any chemical adhesive. The pleated structure greatly expands effective filtration surface area compared with melt‑blown depth filters, achieving higher flow rate, lower pressure loss and larger dirt‑holding capacity within the same physical dimension. Available lengths range from 5‑inch up to 40‑inch; multiple end‑cap configurations satisfy different filter housing requirements. With excellent acid‑alkali resistance, the pp pleated filter performs stably in pH 1‑13 aqueous solutions, and meets food‑contact requirements for beverage and drinking‑water applications.
Standard pp pleated water filters are widely adopted for general‑purpose industrial water filtration. Original branded pp pleated cartridges bring stable performance, yet global buyers frequently face long delivery cycles and high procurement costs. Our aftermarket replacement water filtration pp pleated filters strictly follow standard dimensional tolerance and particle retention specifications. Every batch undergoes bubble‑point test and pressure tightness inspection before shipment, offering reliable cost‑effective filtration solutions for system integrators and end‑users worldwide.
Core specifications of replacement Water Filtration PP Pleated Filter: All‑polypropylene construction; micron ratings optional: 0.1 μm,0.2 μm,0.45 μm,1 μm,3 μm,5 μm,10 μm‑100 μm; available lengths:5/10/20/30/40 inch; end cap types: DOE, 222, 226; O‑ring options: silicone, EPR, NBR, FKM; adhesive‑free thermal‑welded structure; max continuous operating temperature 60℃; recommended replacement differential pressure 2.4 bar, suitable for continuous industrial operation.
Replacement pp pleated filter cartridges can directly interchange most OEM‑brand standard pleated filter housings. It efficiently traps sediment, rust particles, suspended solids and colloidal contaminants, protecting downstream RO membranes, valves and precision process equipment from particle damage.
Filtration Working Principle
Water Filtration PP Pleated Filter applies surface‑plus‑depth combined filtration principle. Under system pressure, raw water flows through the evenly pleated polypropylene filter media. Large‑size particles are intercepted on the outer surface layer, while fine impurities are captured inside multi‑layer gradient pp fiber structure. The uniform pleat layout provides abundant effective filtration area, lowering fluid resistance and maintaining stable throughput during long‑time running. Adhesive‑free thermal‑bond construction avoids secondary contamination caused by adhesive dissolution.
When inlet‑outlet differential pressure rises to 2.4 bar, the pp pleated filter reaches dirt‑holding saturation and needs timely replacement to restore rated flow and filtration efficiency. Timely cartridge change prevents particle breakthrough to protect downstream equipment.

FAQ
Q1: What is Water Filtration PP Pleated Filter used for?
A1: It is general‑purpose industrial pleated filter for removing sediment, rust, suspended solids and colloids, widely used for RO pre‑treatment, food‑beverage, chemical and electronics water treatment.
Q2: What material is pp pleated filter made of?
A2: 100% polypropylene for media, support layers, core and end caps, assembled by thermal‑fusion without adhesive.
Q3: When shall we replace pp pleated filter cartridge?
A3: Replace when inlet‑outlet differential pressure reaches 2.4 bar. High‑turbidity feed‑water will shorten service cycle accordingly.
Q4: Can pp pleated filter be cleaned and reused?
A4: It belongs to disposable pleated consumable. Fine impurities penetrate into filter media; backwashing cannot fully restore filtration performance, disposable replacement is recommended.
Q5: What end‑cap types do you provide?
A5: We supply DOE, 222, 226 end‑cap configurations with multiple O‑ring material options, please confirm housing interface before quotation.
