Woven from high-precision stainless steel wires with uniform aperture and stable structure. Ideal for both coarse and fine filtration of gases and liquids, and commonly used as the base material for various filter elements and sieving equipment.

Composed of multiple layers of woven wire mesh sintered in a vacuum furnace. It offers high mechanical strength, uniform pore distribution, and excellent backwash capability—suitable for high-temperature, high-pressure, and corrosive applications.

Sintered metal felt is made from stainless steel or high-temperature alloy random fibers, which are laid, pressed, and vacuum-sintered to form a three-dimensional porous gradient structure. It features high porosity, excellent dirt-holding capacity, stable filtration accuracy, and the ability to be repeatedly cleaned and regenerated, making it an ideal material for applications requiring high throughput, high precision, and long service life.

Bashan manufactures a wide range of deep-processed filtration products, including pleated sintered mesh filters, powder-sintered filter elements, and wire-wound filter cartridges. These products are widely used in liquid and gas filtration across aerospace, automotive, marine, and chemical equipment applications. They offer excellent corrosion resistance, high-temperature stability, and high-performance filtration.For more than 70 years, we have continuously provided customers with stable, premium-quality, and highly valuable filtration meshes and deep-processed products for both air and liquid filtration needs.Introduction to Filter Assemblies and Filter Cartridges：①Filter AssembliesFilter assembly products are made by combining various specifications of filter mesh with other components. The main types include flat, disc, cylindrical, conical, and rectangular configurations.②Sintered Plate Mesh Filter CartridgesSintered plate mesh filter cartridges are made by laser cutting, rolling, and welding multiple layers of sintered metal mesh. They feature high strength, stable aperture, high-temperature resistance, and excellent pressure-bearing capacity. With a robust structure and stable flow rate, these cartridges are washable and reusable, making them an ideal choice for long-term use in precision filtration applications.                            Key Technical Parameters:Operating Media: Liquid hydrogen, liquid oxygen, liquid nitrogen, hydraulic oil, compressed air, etc.Media Temperature: -252°C to +450°CFilter Material: Stainless Steel 304, 316LDimensions: Minimum inner diameter φ3 mmFiltration Accuracy: 3–500 μmPressure Resistance: Up to 35 MPa ③Powder-Sintered Filter CartridgesPowder-sintered filter cartridges are made by cold pressing metal powders followed by high-temperature sintering, forming a uniform and stable three-dimensional porous structure. They feature high porosity, excellent mechanical strength, precise and controllable filtration accuracy, and outstanding corrosion and high-temperature resistance. With uniform pore distribution and strong dirt-holding capacity, these cartridges can operate stably under high pressure, high temperature, and corrosive media for extended periods.They are widely used in petrochemical plants, gas purification systems, pharmaceutical and food processing, instrument gas treatment, gas distribution and flow control, pyrotechnics and powder spraying processes, hydrogen energy, and new material equipment, making them an ideal choice for high-precision filtration, gas flow stabilization, and safety protection applications.Filter Material: Tin bronze powder, stainless steel powder, high-temperature alloy powder, etc.Dimensions: Minimum φ2 mm × 1 mmFiltration Accuracy: 1 – 60 μmPressure Resistance: Up to 3 MPa④Pleated Filter CartridgesCommon types of pleated filter cartridges include metal mesh pleated cartridges, metal felt pleated cartridges, fiberglass pleated cartridges, and filter paper pleated cartridges.                            Key Technical Parameters:Operating Temperature: -55°C to +225°COperating Pressure: 0–32 MPaFiltration Accuracy: 0.1–500 μm
