Why 316L rather than 304 for sanitary service?

316L's molybdenum content improves corrosion resistance — especially against chlorides and cleaning chemicals — and its low carbon content supports better weld integrity, which matters for hygienic, cleanable surfaces.

Does KOSA support pharmaceutical-grade filtration?

KOSA supplies 316L stainless steel filtration for pharmaceutical, food, beverage and high-purity water duty; final surface finish, documentation and validation support should be confirmed against the specific regulatory requirement.

How are micron rating and extractables handled?

Micron rating is selected to the process cut-off, and material choice (316L, specified media) targets low extractables; KOSA's application notes document representative targets such as 0.1–0.5 micron retention for food & dairy duty.

Where 316L sanitary filtration is specified

Industry	Typical need
Pharmaceutical / biotech	Aseptic-grade clarification, low extractables, cleanability and documentation.
Food & beverage	Hygienic housings, stable particulate removal, CIP-friendly design.
High-purity water	Sub-micron polishing with corrosion-resistant 316L bodies.
Semiconductor / ultra-high-purity	Ultra-low extractables and tight particulate control.

KOSA's published application notes show the level of detail engineered into real programmes — for example, cosmetics formulation lines specifying 0.2 micron absolute retention at up to 45 m³/h, and food & dairy lines specifying 0.1–0.5 micron retention at controlled differential pressure.
