PALL HFU680UY700H13 Equivalent High Flow Pleated Filter Cartridge
Introduction:When designing large-flow industrial water pretreatment, RO membrane protection and coarse filtration systems, filtration engineers and procurement teams require high-capacity Liquid Filters and Self Cleaning Filter solutions to handle high suspended solids loads. The PALL HFU680UY700H13 is an 80-inch high flow pleated filter cartridge with 70μm absolute rating, widely used for high-flow primary filtration and coarse particle removal. However, many end users face high OEM costs and long lead times. This equivalent replacement cartridge is engineered as a direct drop-in solution. It adopts 70μm absolute pleated polypropylene media, inside-to-outside flow construction and EPDM sealing, fully matching the dimensions and performance specifications of PALL HFU680UY700H13 for industrial water and coarse filtration service.

Product Introduction
This industrial high flow filter cartridge is installed inside a large-flow water filter housing to capture large suspended solids, sediment, rust and fibrous impurities. It can be used together with a Self Cleaning Filter to build multi-stage pretreatment protection for RO systems and downstream process equipment. The PALL HFU680UY700H13 equivalent cartridge is an 80-inch high flow pleated filter element with 100% high-purity polypropylene media and EPDM (H13) seals. Its extended 80-inch length provides large effective filtration area and high single-cartridge treatment capacity, making it suitable for ultra-high flow primary filtration and coarse filtration applications. The equivalent replacement cartridge maintains the same overall dimensions, end connection style, inside-to-outside flow path and sealing interface. It can be installed into the existing filter housing without modification, helping users reduce procurement cost and shorten spare part delivery time.
Working Principle
The equivalent PALL HFU680UY700H13 cartridge uses inside-to-outside flow construction. Raw water first enters the inner flow area of the cartridge, then passes outward through the pleated polypropylene media. Large suspended solids, sediment, rust and fibrous impurities are trapped inside the filter pleats, while clarified water flows out from the outer surface of the cartridge into the downstream system.
The 70μm absolute rating is designed for coarse filtration and primary protection. When used with an upstream Self Cleaning Filter, larger particulate loads are removed in advance, helping stabilize differential pressure and extend cartridge service life.

Core Advantages
1. Direct Drop-in Replacement for PALL HFU680UY700H13
Same 80-inch length, 6-inch OD, end connection style, inside-to-outside flow path and EPDM sealing. No housing modification required.
2. 80-Inch Extended Length for Ultra-High Flow Capacity
The 80-inch cartridge provides large effective filtration area and high single-element treatment capacity, suitable for ultra-high flow primary filtration.
3. 70μm Absolute Rating for Coarse Filtration
Capable of capturing large suspended solids, sediment, rust and fibrous impurities, ideal as a first-stage barrier for downstream protection.
4. High Dirt Holding Capacity
Pleated polypropylene media offers high contaminant holding capacity, reducing replacement frequency in high-solids applications.
5. EPDM Seal for Industrial Water Service
EPDM (H13) sealing material offers good compatibility with industrial water and conventional process liquids under normal operating conditions.
6. Compatible with Multi-Stage Filtration Systems
Can be used with upstream self-cleaning filters or pre-filters to remove coarse impurities first, reduce particulate load, stabilize differential pressure and extend cartridge life.
Application Scenarios
Large-flow industrial water pretreatment
RO membrane primary protection
Sediment, rust and fibrous impurity removal
High-solids industrial water filtration
Primary filtration for make-up water and circulating water
Downstream equipment protection
