The 50μm Sintered Felt Metal Mesh Filter is a high-performance depth filtration element manufactured from stainless steel metal fibers through a specialized vacuum sintering process. With dimensions of 90mm in outer diameter and 200mm in length, this sintered felt cartridge is engineered for applications requiring high dirt-holding capacity, excellent permeability, and reliable particle retention in demanding industrial environments .
Unlike woven mesh filters, sintered metal fiber felt is produced from extremely fine stainless steel fibers (with diameters accurate to micrometers) that are randomly laid, stacked, and then sintered at high temperatures to form a three-dimensional porous structure . This non-woven construction creates a filtration medium with pore gradients—different pore diameter layers that achieve higher filtration accuracy and larger dirt-holding capacity than conventional filter media .

Huahang Filter is a specialized manufacturer with deep expertise in sintering technology and industrial filtration solutions. Our focus is on engineering reliable, high-performance metal filters. We control the manufacturing process from raw material selection to final quality testing, ensuring each element meets precise specifications for pore size, strength, and durability. Our team supports customers with technical selection and customization to ensure the filter integrates seamlessly and performs reliably in your specific application.
Q1: How does the sintered mesh filter differ from a standard pleated filter cartridge?
A1: The difference is fundamental. A pleated cartridge typically uses a non-woven media with a nominal rating. Our sintered mesh provides an absolute 20μm rating. Furthermore, the pleated cartridge is disposable, while the sintered mesh element is a durable, cleanable asset designed for hundreds of service cycles, offering a lower total cost of ownership for demanding applications.
Q2: What is the best method to clean this filter, and how do I know it’s clean?
A2: For most applications, ultrasonic cleaning followed by a clean water or solvent rinse is highly effective for removing embedded particles. Backflushing with clean compressed air or liquid is also common. A well-cleaned filter will restore its initial, clean pressure drop when tested with a clean fluid. A significant, irreversible pressure drop indicates the end of its usable life.
Q3: Why choose 304 stainless steel over other materials like 316L?
A3: 304 stainless steel (SS304) offers an excellent balance of corrosion resistance, mechanical properties, and cost for a vast majority of industrial applications involving water, oils, hydraulic fluids, and many chemicals.
Choose 316L stainless steel primarily if your process fluid contains high levels of chlorides (e.g., saltwater, certain acids) where its molybdenum content provides superior pitting resistance.
Q4: Can you provide customized sintered filter?
A4: Yes. We can not only provide the standard size, but also the customized filters. We routinely modify end cap designs (e.g., add NPT threads, O-ring grooves, or flanges) and can adjust the overall length or even the filtration rating to meet your specific system integration requirements and performance goals.
