PALL HFU620UY700H13 Equivalent High Flow Pleated Filter Cartridge
Introduction:When designing compact industrial water pretreatment, RO membrane protection and coarse filtration systems, filtration engineers and procurement teams require reliable high flow filter elements and Self Cleaning Filter solutions to handle high suspended solids loads. The PALL HFU620UY700H13 is a 20-inch high flow pleated filter cartridge with 70μm absolute rating, suitable for compact skid-mounted units and small-flow filtration equipment. Many end users face high OEM costs and long lead times for the original cartridge. 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 HFU620UY700H13 for industrial water and coarse filtration service.

Product Introduction
This industrial high flow filter cartridge is installed inside a compact high flow water filter housing to capture large suspended solids, sediment, rust, leaves 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 HFU620UY700H13 equivalent cartridge is a 20-inch high flow pleated filter element with 100% high-purity polypropylene media and EPDM (H13) seals. Its compact 20-inch length makes it especially suitable for limited installation space, small footprint skid units and small-flow high flow filtration equipment. 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 HFU620UY700H13 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, leaves 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 HFU620UY700H13
Same 20-inch length, 6-inch OD, end connection style, inside-to-outside flow path and EPDM sealing. No housing modification required.
2. Compact 20-Inch Design for Limited Space
The short 20-inch cartridge is ideal for compact skid-mounted units, small footprint equipment and installations with limited vertical space.
3. 70μm Absolute Rating for Coarse Filtration
Capable of capturing large suspended solids, sediment, rust, leaves and fibrous impurities, suitable as a first-stage protective barrier.
4. High Dirt Holding Capacity
Pleated polypropylene media offers high contaminant holding capacity, helping reduce 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
Compact industrial water pretreatment
RO membrane primary protection
Sediment, rust, leaf and fibrous impurity removal
Small-flow high flow filtration equipment
Skid-mounted and compact water treatment units
Downstream equipment protection
