Stainless steel filters are a type of porous metal filter made from industrial metal powder, typically 304 or 316L. The raw material undergoes cold isostatic pressing before being sintered at high temperature and high vacuum conditions. This process results in a filter element with numerous micropores that are curved, criss-crossed, and highly precise, allowing for precise and deep-level filtration through pressurization.

Porous stainless steel filters are highly versatile and widely used in various industries due to their exceptional thermal, chemical, and corrosion resistance. These filters are fabricated by compressing and sintering stainless steel powder to create a porous structure with uniform pore size and distribution. They are widely used in gas and liquid filtration applications, providing efficient and reliable separation of contaminants from the fluid stream.

Features

Uniform pore size and distribution: Porous stainless steel filters have a uniform pore size and distribution, which allows for efficient and reliable separation of particles and contaminants from the fluid stream.

High porosity: The high porosity of porous stainless steel filters provides a large surface area for filtration, enhancing the filtration efficiency and reducing pressure drop.

High thermal stability: Porous stainless steel filters have excellent thermal stability, making them suitable for high-temperature applications.

Chemical and corrosion resistance: Stainless steel is highly resistant to chemical and corrosive environments, making porous stainless steel filters suitable for use in harsh chemical and industrial environments.
