Product Overview
HFU660UY045H13 belongs to the coreless Ultipleat high flow filter series. It has a nominal 60-inch length and 6-inch large outer diameter, adopting single open-end design with inside-to-outside flow pattern. The filter media is UY-grade pleated polypropylene, rated at 4.5 micron. End caps and integrated lifting handle are built with glass fiber reinforced polypropylene. EPDM O-ring seal comes as standard; silicone, Buna-N and FKM seals are available to adapt to diverse chemical working conditions. Thermal welding technology is applied for all joints, no adhesive is used, eliminating secondary contamination risk. The unique overlapping crescent pleat layout maximizes available filtration area, delivering larger flow per cartridge and cutting down the total quantity of filter vessels required for the whole system. This interchangeable filter cartridge is widely used in seawater desalination, power plant water systems, petrochemical process water, municipal water supply and large-scale RO security filtration projects.
Working Principle
HFU660UY045H13 high flow filter cartridge runs on inside-to-outside radial filtration principle. Raw liquid flows into the inner cavity through the single open top end and passes radially outward through multi-layer pleated polypropylene media. Larger particles get captured on the inner pleat layers, while fine particles are retained via depth filtration inside the overlapping crescent pleats. This special pleat geometry evenly distributes fluid flow, prevents localized clogging and slows the rising speed of differential pressure. After purification, treated liquid flows outwards from the filter’s outer surface. Precision O-ring seal stops bypass of unfiltered fluid. All trapped contaminants remain inside the filter cartridge, making replacement and waste disposal safer. It functions as security pre-filtration, greatly lowering impurity load for downstream RO, NF membrane and ion exchange resin equipment.

Compatibility & Cross Reference
FAQ
Q1: Can HFU660UY045H13 fit my existing filter housing?
A1: Yes. It adopts standard 60-inch 6-inch large-diameter coreless inside-out structure, fully universal for HFU660 series filter vessels.
Q2: When should I replace the filter cartridge?
A2: Replace immediately when the pressure difference reaches 2.0 bar (29 psid). The service life varies according to raw water turbidity and impurity content.
Q3: What is the maximum temperature resistance?
A3: The maximum continuous working temperature is 82℃. Excessive temperature will cause deformation of polypropylene filter media and reduce filtration effect.
Q4: Can you provide customized specifications?
A4: Yes. We support multiple micron grades and customized seal materials to meet different industrial working conditions.
Q5: What is the bulk order production lead time?
A5: Standard stock cartridges have lead time of 7-15 working days after deposit confirmation. Customized products require negotiable production cycle.
