Product Overview
HFU660UY200H13 belongs to the long-size 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 20 micron. End caps and integrated lifting handle are constructed with glass fiber reinforced polypropylene for robust mechanical strength. EPDM O-ring seal is standard configuration; silicone, Buna-N and FKM seals are optional to adapt to diverse chemical working conditions.
All joints use thermal welding technology without adhesive, eliminating secondary contamination risk. The exclusive overlapping crescent pleat layout maximizes available filtration area, delivering very high flow per single cartridge and cutting down the total quantity of filter vessels required for the whole water treatment system. This interchangeable filter cartridge is widely deployed in seawater desalination, power plant water systems, petrochemical process water, municipal raw water supply and large-scale RO security pre-filtration projects.
Working Principle
HFU660UY200H13 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 like sand, rust flakes and coarse suspended solids get captured on the inner pleat layers, while smaller 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 primary security pre-filtration, greatly lowering impurity load for downstream RO, NF membrane and ion exchange resin equipment.
Core Technical Specifications
Core Advantages
Core-less crescent pleat technology:
Removes internal support skeleton, maximizes filtration area, achieves ultra-high flow rate, reduces cartridge count and lowers overall project capital cost for large water treatment systems.
20μm coarse depth filtration:
UY polypropylene media provides excellent capacity for capturing large particles and sediment, ideal for raw water pre-treatment to reduce the burden on fine filtration stages.
Broad chemical compatibility:
Full polypropylene construction provides good acid and alkali resistance, compatible with most industrial water and general process liquid working environments. Multiple seal material selections handle corrosive fluid applications.
Simple maintenance with single open-end:
Built-in lifting handle enables quick tool-free on-site replacement. Pollutants stay trapped inside the cartridge for safer handling. Thermal welded structure eliminates glue contamination risk.
Drop-in interchange replacement:
Manufactured by LEFILTER China, fully matched in dimension, interface and flow performance. Helps global industrial buyers and engineering contractors reduce spare part procurement cost.
Main Application Scenarios
Reverse osmosis security pre-filtration for large-scale seawater desalination plants
Power plant boiler feed-water and condensate-water pretreatment
Petrochemical and fine-chemical process liquid filtration
Large-scale municipal raw water-supply pretreatment systems
Ion-exchange resin protection filtration for water-treatment workshops
Industrial circulating water and wastewater reuse pre-filtration
Compatibility & Cross Reference
FAQ
Q1: Can HFU660UY200H13 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.
