SMF® Technology

SMF® is a cutting edge, microporous stainless steel filter media, designed for demanding applications.

An ultra-fine metal powder is precision applied to an expanded metal carrier and sintered under carefully controlled conditions, creating a seamless, cohesive structure. The resulting 0.4 mm thin coil band material delivers exceptional mechanical strength, outstanding thermal resistance, and unparalleled durability setting the standard for high performance filtration solutions.

SMF®-Sintermetallfilter zeichnen sich aus durch niedrige Differenzdrücke, hohe Temperaturbeständigkeit, lange Standzeiten und die Möglichkeit zur Rückspülung im laufenden Betrieb. Durch spezielle Beschichtungen lassen sich zudem katalytische Eigenschaften und funktionale Oberflächen realisieren. Die Filter sind elektrisch leitfähig für explosionsgeschützte Anwendungen, vollständig recycelbar und vereinen damit höchste technische Leistungsfähigkeit mit einem klaren Beitrag zur Nachhaltigkeit.

SMF® Manufacturing Process

Step 1: For further processing the high alloy metal powder is mixed with a binder
