Product Introduction
This HFU660UY700Z high flow filter cartridge equivalent is engineered for severe industrial filtration environments. As a core consumable for industrial water filter systems, this high flow filter cartridge can be integrated with self-cleaning filter to establish multi-stage pretreatment workflows. Adopting 100% high-purity polypropylene HDC II deep pleated media and Viton / FKM fluororubber sealing ring, this replacement cartridge perfectly matches the size, inside-to-outside flow path and end cap structure of the original HFU660UY700Z. It is designed for 70 micron absolute pre-filtration, with 60-inch long body and 6-inch outer diameter. The fluororubber seal stands up to hydrocarbons, strong oxidants, petroleum-based liquids and solvents, solving the aging and swelling issues that regular EPDM gaskets face in tough media. No filter housing modification is required during installation. It is widely adopted in petrochemical, power generation and chemical refining for high flow coarse filtration and equipment protection.
Working Principle
This HFU660UY700Z equivalent high flow filter cartridge uses inside-to-outside flow construction. Unfiltered liquid flows into the central inner core and then passes radially outward through the deep pleated polypropylene media. Solid particles and suspended contaminants are trapped within the pleated layers, while clarified liquid flows out from the cartridge outer surface. The HDC II deep pleated structure greatly expands effective filtration area, achieving large dirt holding capacity and high liquid throughput. When combined with upstream self-cleaning filter, bulk coarse impurities are intercepted in advance, slowing the rise of differential pressure and extending the service cycle of the filter cartridge, even under elevated temperature and chemically challenging working fluids.

FAQ
Q1: Can this cartridge directly replace HFU660UY700Z filter cartridge?
A1: Yes. It adopts matching size, deep pleated media and Viton sealing design, it can be installed directly into the original filter housing.
Q2: What makes the Viton seal version better than EPDM?
A2: Viton / FKM fluororubber features superior resistance to oil, hydrocarbons, solvents and high temperature, and will not easily swell or corrode in aggressive liquids.
Q3: What is the maximum continuous operating temperature?
A3: The maximum continuous operating temperature reaches up to 82℃.
Q4: When do we need to replace this high flow filter cartridge?
A4: It is recommended to replace the filter when differential pressure rises to 2.1 bar, and the maximum allowable forward differential pressure is 3.4 ~ 4.0 bar.
Q5: What filtration rating is this HFU660UY700Z equivalent cartridge?
A5: It is 70 micron absolute filtration grade for coarse pre-filtration.
