Product Introduction
This replacement HFR20A005D high flow filter cartridge is a high-performance industrial grade filter element, designed for harsh industrial, chemical and high impurity liquid filtration scenarios. The high flow filter cartridge features large outer diameter structure with built-in heavy-duty inner support core, compatible with standard water filter housing for quick installation and replacement. When matched with self-cleaning filter configuration in the whole liquid processing line, it effectively protects downstream equipment such as RO and UF membranes from particulate contamination. Adopting lofted special microfiber composite medium and innovative radial pleat technology, it packs massive filtration area into one compact single cartridge. Compared with traditional small diameter filter cartridges, it provides much higher contaminant holding capacity, lower initial pressure drop and excellent mechanical strength. It can directly replace conventional small diameter filter assemblies to cut down cartridge replacement frequency and manual maintenance cost.
Working Principle
Liquid flow path:
Liquid flows from outside to inside (or inside to outside) of the cartridge, passing through the large-area pleated medium layer.
Gradient depth capture & surface retention:
5μm absolute precision physical interception: With unique fiber pore size distribution, it accurately captures suspended particles, colloids and impurities larger than 5 microns.
Depth dirt holding:
The porous and lofted medium structure allows particles to penetrate deep inside the filter material instead of blocking instantly on the surface. It maintains stable filtrate quality and achieves extended service life.

Key Advantages
Exceptional dirt holding capacity:
Thanks to special microfiber and radial pleated design, its dirt holding capacity far exceeds ordinary filter cartridges, greatly extending replacement intervals.
Low pressure drop & high flow rate:
Single 20-inch cartridge supports large treatment flow. Pressure drop rises slowly during operation to save energy consumption.
Excellent chemical compatibility:
The material has great tolerance for a wide range of industrial chemicals and acid & alkaline fluids.
Robust construction:
The reinforced support core can resist water hammer and high differential pressure impact, preventing cartridge collapse under high flow impact.
Application Scenarios
Industrial water treatment:
Pre-security filtration for reverse osmosis (RO) systems and protection filtration for ultrafiltration (UF) systems.
Chemical and fine chemical industry:
Purification of process liquids, chemical raw materials, cooling water and circulating water.
General industrial manufacturing:
High-efficiency clarification filtration for electroplating liquid, paint, solvent and washing liquid.
Power & energy industry:
Condensate filtration and auxiliary water system treatment in power plants.
FAQ
Q1: Is HFR20A005D compatible with standard high flow filter housings?
A: Yes. It adopts standard industrial high flow outer diameter of about 6.5 inch. It fits most mainstream high flow filter housings on the market that follow the 3-inch core shaft standard.
Q2: What does suffix “D” stand for?
A: Code "D" refers to special chemical resistant sealing gasket. It performs better than normal EPDM or nitrile rubber when handling oil, strong polar solvents and certain chemical media. Always verify compatibility with your actual fluid before purchase.
Q3: How to know when to replace this high flow filter cartridge?
A: Monitor the pressure difference between filter inlet and outlet. Replacement is required when differential pressure reaches 0.15–0.2 MPa (20–30 psi), or the flow rate drops significantly.
Q4: What is the main benefit of radial pleat design?
A: Radial pleat maximizes the effective filtration area inside limited cartridge volume. More area means longer service cycle and slower pressure rise.
Q5: Can this cartridge work in continuous 24-hour running industrial system?
A: Yes. The reinforced inner core and stable microfiber medium support continuous operation for most industrial liquid filtration applications within the recommended temperature and pressure range.
