70MPa = Even at 700 atmospheres of high-pressure hydrogen! The potential of stainless steel sintered mesh.
Proven track record as a gas filter for hydrogen, helium, nitrogen, oxygen, argon, and others. Designed, prototyped, and mass-produced according to specifications through the application of unique technology.
【Filtration Precision】 From approximately 2μm and 5μm to several millimeters. 【Standard Materials】 Stainless steel, SUS316 and 316L. 【Adopted Environments】 Line pressure 70 MPa, -50°C compressed hydrogen. Line pressure 20 MPa, 300°C molten resin. Other filtration applications for food, pharmaceuticals, industrial gases, polymers, etc., as elements for rectification, pressure reduction, foaming, air supply, degassing, and powder transport. 【Differential Pressure Strength (Example in Cylindrical Shape)】 Outer diameter φ10mm × length L15mm: withstands external pressure 30 MPa Outer diameter φ20mm × length L15mm: withstands external pressure 15 MPa *Determined by visual deformation. *This is the differential pressure strength of the element, not the line pressure.

basic information
【Features】 Mainly uses woven wire mesh and etching as materials. This leads to improvements in material loss and detachment. It is a filter product with excellent heat resistance, pressure resistance, and corrosion resistance. Custom specifications can be designed to meet the user's design considerations and existing equipment. 【Diffusion Bonding (Sintering) Technology】 This method utilizes the diffusion of atoms in the stainless steel base material caused by the temperature and atmosphere inside the furnace for bonding. By recrystallizing across the layers, it forms a monolithic structure made of a single material without the use of binders. *For more details, please refer to the materials.
