JINTAI high purity gas filter elements are manufactured from high-purity 316L stainless steel powder or nickel-based alloy powder through high-temperature sintering.
The all-metal porous structure provides filtration ratings down to 3 nm and can be used in compatible bulk-gas, process-gas and vacuum environments. Dimensions can be customized, and an asymmetric sintered structure is available for applications requiring higher flow within a limited component volume.
This product is made of high-purity 316L stainless steel or nickel-based alloy powder, sintered at high temperature, with a maximum filtration rating of 3 nm. Its all-metal structure makes it suitable for applications compatible with metallic materials, such as bulk gases, process gases, and vacuum environments. For high-flow-rate scenarios, an asymmetric sintered powder filter element is also available, offering higher flow capacity at the same volume without compromising filtration accuracy — making it an ideal new choice for advanced semiconductor manufacturing processes.

The current product page states a maximum filtration rating of 3 nm. The applicable filtration efficiency, test method, gas, flow rate and differential pressure should be confirmed for the selected element.
Two material groups are currently identified:
High-purity 316L stainless steel powder
Nickel-based alloy powder
Material selection should be based on gas chemistry, temperature, pressure and required corrosion resistance.
The sintered construction avoids polymeric filter media within the porous element and is intended for applications compatible with metallic materials.
The element geometry can be adjusted according to the available installation space, required filter area and connection design.
The asymmetric structure provides an option where a conventional uniform porous element would create excessive pressure drop or insufficient flow within the available volume.
