Product Overview
HFU640UY090H13 is a 40-inch coreless high flow filter cartridge belonging to the UY Ultipleat series. It adopts 6-inch large outer diameter, single open-end structure and inside-to-outside radial filtration mode. The filter media is high-purity UY-grade polypropylene pleated material with stable 9μm filtration rating. All joints are thermally welded without adhesive, avoiding secondary contamination. The end cap and integrated lifting handle are made of reinforced polypropylene for high mechanical strength. Standard EPDM O-ring ensures tight sealing, while silicone, FKM and Buna-N seals are optional for various chemical environments. The unique crescent overlapping pleat structure maximizes filtration area, achieving high flow rate with fewer cartridges and greatly reducing filter housing investment and maintenance costs. It is widely applicable for seawater desalination, power plant feed water, petrochemical process water, municipal water supply and industrial circulating water pretreatment.
Working Principle
HFU640UY090H13 high flow filter cartridge adopts professional inside-to-outside filtration principle. Raw water enters from the top open end into the inner cavity and flows radially outward through multi-layer gradient pleated polypropylene media. Larger particles are intercepted on the inner pleated layers, while fine particles and colloids are trapped by depth filtration inside dense crescent pleats. The optimized pleat structure uniformizes water flow distribution, prevents local blockage and slows differential pressure increase. After full purification, clean water flows out from the outer surface of the cartridge. Precision O-ring sealing completely avoids unfiltered liquid bypass, ensuring stable and consistent 9μm filtration efficiency throughout operation. All contaminants remain inside the cartridge for safe and fast replacement.

Compatibility & Cross Reference
FAQ
Q1: Is HFU640UY090H13 compatible with original Pall filter housings?
A1: Yes. It adopts standard 40-inch 6-inch coreless single open-end structure, fully matching HFU640 series filter vessels.
Q2: When should I replace the filter cartridge?
A2: Replace when differential pressure reaches 2.0 bar (29 psid). Actual service life depends on raw water turbidity and impurity content.
Q3: What is the maximum working temperature?
A3: The maximum continuous operating temperature is 82℃. Excessively high temperature will cause media deformation and reduce filtration performance.
Q4: Can you provide customized specifications?
A4: Yes, customized seal materials and special micron grades are available for bulk project orders.
Q5: What is the delivery cycle?
A5: Standard products are shipped within 7–15 working days. Customized orders require negotiable production time.
