Frequently Asked Questions
-
Q: What is the difference between 304 and 316L stainless steel for this filter cartridge?
A: Both grades offer excellent corrosion resistance. 316L contains molybdenum, providing superior resistance to chlorides and acidic environments, making it ideal for marine or chemical applications. For general water and oil filtration, 304 is sufficient and more cost-effective. -
Q: Can this cartridge be cleaned and reused?
A: Yes, depending on the construction (pleated or wound). Pleated stainless steel cartridges can be backwashed or chemically cleaned. Wound cartridges are typically disposable. Please specify your preferred type when ordering. -
Q: Does the 300 PSI rating apply at all temperatures?
A: The pressure rating is based on ambient temperature (20°C). At higher temperatures, the maximum allowable pressure may decrease. Please consult our technical team for derating factors at your specific operating temperature. -
Q: What is the standard NPT thread size?
A: The standard size is 1-inch NPT male or female, depending on your housing. We also offer 1.5-inch NPT and custom sizes. Please confirm your requirement before ordering. -
Q: How long is the lifespan of this cartridge?
A: Lifespan depends on the operating conditions, fluid quality, and maintenance. In typical water filtration applications, the cartridge can last 6-12 months before replacement or cleaning is needed. -
Q: Can I get a sample for testing before bulk order?
A: Yes, we provide samples for evaluation. Sample cost and shipping charges apply. Please contact our sales team to arrange a sample. -
Q: Is the cartridge suitable for potable water?
A: Yes, when made with food-grade stainless steel and appropriate gaskets (EPDM or silicone), it is safe for potable water applications. We can provide FDA-compliant materials upon request. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 50 pieces per size. For smaller quantities, please inquire about stock availability or sample orders.
