Frequently Asked Questions (FAQ)
Q1: What is the filtration rating of RCP045-60NPP replacement filter?
A: The RCP045-60NPP replacement filter configuration uses 4.5 μm pleated polypropylene media with a stated retention efficiency of 99.98% for fine particulate removal in industrial liquid filtration.
Q2: What is the difference between RCP045-60NPP and RCP100-60EPP?
A: RCP045-60NPP uses a 4.5 μm filtration configuration with Buna-N sealing, while RCP100-60EPP uses a different micron rating and EPDM seal configuration. Final model selection should be based on filtration requirements and process-fluid compatibility.
Q3: Is MemKway RCP045-60NPP equivalent filter designed for Parker ParMax systems?
A: Yes. It is designed as a compatible alternative for selected Parker Fulflo ParMax applications. Final fit should be confirmed using the complete OEM part number, dimensions and seal configuration.
Q4: When should the RCP045-60NPP compatible filter cartridge be replaced?
A: Replacement should be based on differential pressure, flow performance and process requirements. Usually 35 psid (2.4 bar) as the recommended change-out differential pressure.
