Ultrafine metal fiber for semi-conductor gas filter/High Purity Gas
Filters Solution has their unique properties such as high surface
area, thermal/chemical stability, and mechanical durability. These
materials are particularly useful in industries requiring precision
gas purification, such as semiconductor manufacturing, automotive
emissions control, and industrial air quality management.
Applications of Ultrafine Metal Fiber in Gas Filtration
Semiconductor Manufacturing
High-Purity Gas Filtration: Removes sub-micron particulates and chemical contaminants from
process gases (e.g., N₂, Ar, H₂) used in chip fabrication.
Corrosive Gas Handling: Resists degradation from aggressive gases (e.g., HF, Cl₂) in
etching and deposition processes.
Automotive & Emissions Control
Exhaust Gas Filtration: Captures fine particulate matter (PM2.5) and NOₓ in catalytic
converters.
Hydrogen Fuel Cells: Filters impurities from hydrogen feed gas to enhance fuel cell
efficiency.
Industrial & Environmental Air Purification
Volatile Organic Compound (VOC) Removal: Metal fiber filters with catalytic coatings break down harmful
VOCs.
High-Temperature Filtration: Used in power plants and metal processing to filter hot exhaust
gases.
Medical & Pharmaceutical
Sterile Gas Filtration: Ensures ultra-clean air for pharmaceutical production and
medical-grade gas supply.
Key Advantages of Metal Fiber Filters
High Porosity & Low Pressure Drop: Efficient gas flow with minimal energy loss.
Thermal Resistance: Withstands extreme temperatures (up to 1000°C for some alloys).
Chemical Inertness: Resists acids, alkalis, and solvents.
Reusable & Cleanable: Unlike polymer filters, metal fibers can be regenerated via heat
or chemical cleaning.
