Your Trusted Supplier Of Industrial Pleated Filter Cartridges
Our pleated filter cartridges deliver exceptional performance that standard depth filters cannot match—specifically, a larger effective filtration area, lower differential pressure, and an extended service life. We offer cartridges constructed from PP, PTFE, PES, and sintered materials, with filtration ratings ranging from sub-micron levels up to 100 µm. Choosing Lianda Filtration is your smartest choice.
Our Products
DP-01 Polypropylene (PP) filter cartridge is made from high-quality Chinese / imported PP membrane. It combines low cost, high flow, and relatively high retention rate.DP-01 is the most widely used filter cartridge in micro-porous precision filtration applications.
DP-02 high-precision polypropylene (PP) filter cartridge is made of a multi-layer gradient rating PP membrane. It is the upgrade of DP-01.
150HFF high flow rate filter cartridge is a substitute for the PP melt-blown filter and normal pleated filter cartridge for high flow rate working conditions. It has multi-layer membranes with a gradient filter rating. The dirty holding capacity, retention rate and life span are improved.
LDPT PTFE filter cartridge is an absolute filter rating cartridge made from a PTFE membrane. It has excellent resistance to organic and inorganic corrosive solutions and instinctive hydrophobicity.
LDPG PTFE filter cartridge is made from a hydrophobic PTFE membrane. It is suitable for high flow velocity, low pressure drop, and GMP standard gas sterilization applications.
The sterilizing filter element has super high precision and high interception efficiency.
CPLD capsule filter is suitable for small flow rate filtration (such as pharmaceutical, inkjet, and specific industries, where the waste of liquid is minor).
FY filter bag has good chemical compatibility and heat resistance. It is relatively lowest cost comparing to the filtering effect and is the most widely used filter element for industrial filtration applications.
Pleated Filter Cartridge Features
From 0.1 to 100 µm — absolute-rated membrane to coarse pre-filtration, all in our lineup.
Pleated structure gives 2–5× more surface area than standard depth filters.
Less pressure drop means lower pump energy and longer service between changeouts.
PP, PTFE, PES options cover pH 1–14 and handle acids, bases, solvents, and oxidizers.
Every filter element passes integrity testing before it leaves our facility.
Thermally bonded all-PP construction — no binders, no surfactants, no secondary pollution.
PE and PA sintered cartridges are cleanable and reusable for lower cost-per-cycle.
DOE, 222/226, high-flow plug-in, and custom end caps fit your existing housings.
Industrial Filtration: Choose the Right Material
In the field of industrial filtration, selecting the wrong filtration material is one of the most common—and most costly—mistakes. Our range of pleated filter cartridges is designed to completely eliminate this risk. For broad chemical compatibility, you can opt for PP materials; if your process fluid is corrosive to other membrane types, you can choose hydrophobic or hydrophilic PTFE; if you require high-throughput filtration efficiency combined with pharmaceutical-grade bioburden control, asymmetric PES is the ideal choice; and if you need a robust, reusable structure that maintains dimensional stability even when subjected to thermal cycling and mechanical stress, our sintered PE or PA filter elements are the perfect solution.
The Lianda Pleated Filter Cartridge Guarantee
We manufacture our own pleated filter cartridges on automated production lines under ISO 9001-certified quality management. You’re not buying from a re-labeler or a trading company. Every element is assembled, integrity-tested, and documented in our own facility — which means consistent quality, reliable lead times, and full traceability from raw material to finished product. When something needs to change, you talk directly to the people who make it.
The application of pleated filter cartridges spans a wide range of industries, including pharmaceuticals, biotechnology, food and beverages, industrial water treatment, chemical processing, electronics and semiconductors, and oil and gas, among others.
Generally speaking, this is certainly possible. We offer standard lengths such as 10″, 20″, 30″, and 40″, as well as the most common end-cap configurations: DOE (Double Open End), 222 O-ring, 226 O-ring, Fin-type, and large-diameter high-flow styles. Simply provide us with the original manufacturer’s model number, and we will match you with the appropriate specifications.
Yes. Our PP and PES filter cartridges are manufactured using materials compliant with FDA Title 21 CFR regulations and meet USP Class VI biocompatibility requirements. Our production processes adhere to ISO 9001 quality management standards, and every filter cartridge undergoes 100% integrity testing prior to shipment.
