Frequently Asked Questions (FAQ)
A1: Yes. MK-U-640PP005E is designed as a direct Pall HFU640UY005J replacement, matching the key dimensions, flow configuration and installation requirements for compatible high flow filter housings.
A2: HFU640UY005J corresponds to absolute 0.5 μm filtration grade. MemKway MK-U-640PP005E is designed for fine particulate removal in demanding industrial water and process filtration applications.
A3: A 0.5 μm cartridge is generally selected when finer particulate control is required. A 5 μm cartridge is typically used where coarser pretreatment is sufficient and lower initial pressure drop or higher solids loading is a priority. Final selection should be based on feed-water quality and downstream process requirements.
A4: It is designed for use in compatible Pall Ultipleat High Flow housings. Before ordering, confirm the OEM part number, cartridge length, end connection and seal material to ensure the correct configuration.
A5: Please provide the OEM part number, required quantity, seal material and relevant operating conditions. Photos, dimensions or an existing filter specification can also be used for cross-reference verification.
A6: Yes. MemKway supports sample evaluation, OEM/private labeling, customized packaging and bulk supply for distributors and industrial filtration customers.
