1. Q1: Which material grades are available for the metal filter element?
   A1: Options include SS304, SS316L, Inconel, Hastelloy. Each offers specific corrosion resistance and temperature performance. SS316L is standard for chemical/pharma use due to its high pitting resistance.
2. Q2: What pore sizes do you offer and how are they classified?
   A2: Standard pore sizes range from 1–200μm, measured by mercury intrusion or bubble point test. "Fine" class (1–10μm) for polishing, "Medium" (20–50μm) for pre-filtration, "Coarse" (>50μm) for solids capture.
3. Q3: Do the filters meet international standards (ISO/ANSI)?
   A3: Yes. All metal filter element series are manufactured and tested per ISO 16889, ASTM A967, ANSI B16.5 and can be supplied with FDA CFR21 certificates for food & pharma.
4. Q4: How is the activated carbon integrated into the cartridge?
   A4: Activated carbon is filled or adhered onto the metal mesh or shell via compression or in-situ thermal bonding—ensuring tight fit, no channeling, and optimal contact area for adsorption.
5. Q5: Which installation standards are supported (connections, housings)?
   A5: Flange (ANSI/DIN/JIS), threaded (BSP/NPT), code 7/226 bayonet, SOE/DOE. Custom lengths and adapters are available for retrofit or new builds.
6. Q6: What is your typical quality assurance/test process?
   A6: 100% inline testing: leak/pressure test, dimensional inspection, surface passivation check, and functional efficacy verification against reference challenge (ISO 16889).
7. Q7: Can I specify custom end caps, gaskets, or shell coatings?
   A7: Absolutely. End caps (ABS, SS, carbon steel), gaskets (EPDM, Viton, PTFE), and exterior surface coatings (electro-polish, powder coat) are available to meet process needs.

The advances in metal filter element technology—especially when integrated with activated carbon cartridge and activated carbon filter element solutions—offer unparalleled safety, filter longevity, and compliance with international standards.
