Application
1. Gas Chromatography (GC) and Analytical Instruments
*Protect sensitive detectors and columns from particulate contamination
*Used as pre-filters in laboratory gas lines (e.g., carrier gas purification)
2. Semiconductor & Electronics Manufacturing
*Filter ultra-pure gases (e.g., nitrogen, argon, hydrogen) used in wafer processing
*Prevent contamination in gas cabinets and point-of-use systems
3. Chemical and Petrochemical Processing
*Inline filtering of process gases and liquids to protect downstream valves and regulators
*Corrosion-resistant 316L filters handle aggressive media
4. Instrumentation and Control Systems
*Installed before pressure regulators, transmitters, and gauges to prevent blockage
*Ensure clean flow in compact instrumentation panels
5. Pharmaceutical and Biotech Facilities
*Inline filtration of inert gases like nitrogen in cleanroom operations
*Sanitary-compatible filtering of process liquids in small-volume systems
6. Food and Beverage Industry
*Filtration of CO₂ or nitrogen in bottling and packaging systems
*Suitable for low-volume CIP (Clean-in-Place) gas lines
7. Hydrogen Fuel Systems & Energy Sector
*Inline filters for hydrogen pipelines or hydrogen generator outlets
*Ensures protection of MFCs (mass flow controllers) and sensors
8. Vacuum Systems and Sampling Lines
*Installed in vacuum exhaust systems to prevent back-contamination
*Used in environmental sampling equipment for gas or vapor filtration
