Frequently Asked Questions

Sintered filters are filter elements crafted from metal (316L stainless steel, Inconel, bronze, Monel, pure nickel, or stainless steel mesh/felt) or plastic particles, are produced through uniaxial powder compaction in a rigid mold, followed by high-temperature sintering. They have high strength, corrosion resistance, and excellent filtering accuracy, and are widely used in the chemical, pharmaceutical, and food industries.

We offer a wide range of materials, including stainless steel (304 and 316), bronze, inconel, monel, nickel, plastic PE PP powder, and stainless steel wire mesh, or felt. We can customize it to your needs.

Sintered filters outperform conventional filter elements, with longer life and higher filtration efficiency for demanding industrial applications. Their uniform pore structure and high mechanical strength allow for repeated cleaning, improving performance and durability.

Our filters support backwashing and ultrasonic cleaning, depending on the material and type of contaminants. We provide detailed maintenance guidelines to ensure long-term use.

Yes. We can provide customized services for filter material, pore size, diameter and height size, shape, connector type, and other parameters according to the customer’s drawing and applications.

Yes, we can provide sample testing (a sample fee will be charged) and full technical datasheet support.

It depends on the product type and degree of customization. If we have it in stock, any quantity is acceptable. For customized products, the MOQ is typically 10 pieces; please contact us for a specific quote.

Yes. We provideinternal test reports at the factory, and can also assist in providing third-party laboratory testing and certification services if necessary.

Standard products are usually shipped within 10 working days because we have them in stock; customized products depending on the design and production line arrangement, and the average is 20-25 working days.

We are direct manufacturer specializing in sintered metal filters.
