6. Key Features & Benefits
10 μm Absolute Filtration
Provides reliable removal of suspended solids and particulate contaminants with a 10 μm absolute filtration rating, suitable for general industrial pretreatment applications.
Higher Solids-Loading Capability
The 10 μm rating is well suited to applications where feed water contains higher particulate loading and ultra-fine filtration is not required.
40-Inch High Flow Design
The large-diameter 40-inch pleated cartridge supports water flow rates up to 350 GPM (1,325 LPM) under suitable operating conditions while reducing the number of cartridges required.
High Dirt-Holding Capacity
Large-area pleated polypropylene media provides high contaminant-loading capacity, helping extend operating cycles between cartridge changeouts.
Direct Replacement Design
Engineered to match the key dimensional, flow and installation requirements of Pall HFU640UY100J for straightforward replacement in compatible Ultipleat High Flow housings.
7. When Should You Choose a 10 μm HFU640UY100J Replacement?
A 10 μm absolute cartridge is a practical choice when the primary filtration objective is to remove larger suspended solids and reduce particulate loading before downstream treatment. Compared with finer 1–5 μm cartridges, a 10 μm element may be better suited to feed streams with higher solids loading where ultra-fine particulate control is not required.
For applications requiring finer particulate control, consider the HFU640UY050J Replacement Filter, featuring a 5 μm rating in the same 40-inch configuration. For coarser pretreatment or higher contaminant-loading conditions, 20 μm and larger ratings can also be considered. Final selection should be based on feed-water quality and downstream equipment requirements.
Need the same 10 μm absolute filtration rating in a 60-inch configuration? See the HFU660UY100J Replacement Filter for higher-throughput filtration systems.
