Products Description
Brief Introduction
Stainless Steel Filters are filtration devices primarily manufactured from 304/316L stainless steel, utilizing filter elements such as sintered mesh, woven wire mesh, or filter felt to achieve solid-liquid or solid-gas separation. Their core value lies in providing a mechanically stable, chemically compatible, and easily maintainable filtration solution, widely used in industrial applications requiring hygiene, corrosion resistance, or high-temperature capability.
