Product Overview
HFU640UY045H13 belongs to the 40-inch coreless Ultipleat high flow filter series. Compared with 60-inch HFU660 series, this 40-inch shorter body is more suitable for filter vessels with limited height space. It has nominal 40-inch length and 6-inch large outer diameter, single open-end structure with inside-to-outside flow pattern. The filter media is UY-grade pleated polypropylene with 4.5μm stable precision. End caps and integrated lifting handle are manufactured from glass fiber reinforced polypropylene for good structural strength.
EPDM O-ring seal is the standard configuration; silicone, Buna-N and FKM seals are available for different chemical liquid conditions. All joints are connected by thermal welding technology without adhesive, eliminating secondary contamination risk. Unique overlapping crescent pleat design maximizes effective filtration area, delivering high throughput and cutting down the total number of cartridges required for medium-size filtration systems. This interchangeable filter cartridge is commonly deployed for medium-scale seawater desalination, power plant condensate water, food & beverage production water and municipal water pretreatment.
Working Principle
HFU640UY045H13 high flow filter cartridge works on inside-to-outside radial filtration principle. Raw liquid flows into the inner hollow cavity from the top single opening and passes radially outward through multi-layer gradient crescent pleated polypropylene media. Coarse particles are trapped on the inner pleat layers, while fine silt and colloidal impurities are deeply intercepted by the dense outer filter layers.
The special crescent overlapping pleat layout optimizes fluid distribution and avoids local clogging, slowing the rise of differential pressure during continuous operation. After purification, treated liquid flows out from the outer surface of the filter cartridge. Precision O-ring seal prevents bypass of unfiltered fluid to guarantee consistent 4.5μm filtration efficiency. All trapped contaminants stay locked inside the cartridge, which makes on-site replacement safer and cleaner. It serves as security pre-filter to reduce impurity load and protect downstream membrane systems.

Compatibility & Cross Reference
FAQ
Q1: Is HFU640UY045H13 shorter than HFU660 series?
A1: Yes. It is 40-inch long, shorter than 60-inch HFU660 series, suitable for filter tanks with limited vertical installation height.
Q2: When to replace this filter cartridge?
A2: Replace it once the system differential pressure reaches 2.0 bar (29 psid). Actual service life depends on raw water turbidity and impurity concentration.
Q3: What is the maximum continuous working temperature?
A3: Max continuous operating temperature is 82℃. Operation beyond this temperature limit will deform polypropylene media and reduce filtration efficiency.
Q4: Can I customize the seal material?
A4: Yes. Silicone, Buna-N and FKM seals are available for special chemical liquid and high temperature applications.
Q5: What is the bulk production lead time?
A5: Standard stock items can be shipped within 7-15 working days after deposit. Customized bulk orders need negotiated production schedule.
