  • High temperature resistance, normal use below 550 degrees Celsius.

  • High filtration accuracy, stable pores, can effectively remove suspended solids and particles, etc., excellent filtration accuracy and good purification effect.

  • Good air permeability and low pressure loss. High porosity, uniform pore size, small initial resistance, easy backflushing, online regeneration, easy cleaning, strong regeneration ability and long service life.

  • High mechanical strength, good rigidity, good plasticity, no need for additional framework support protection, simple installation and use, easy maintenance, good assembly, welding, bonding and mechanical processing

  • Porosity is uniform, especially suitable for occasions with high uniformity such as fluid distribution and homogenization treatment.

  • Filtration accuracy: 0.2 ~ 80μm.

  • No particles fall off, so that the original liquid does not form secondary pollution.

  • Good mechanical performance, low pressure difference, large flow rate, pressure filtration and suction filtration, simple operation.

  • Good corrosion resistance, can be used stably in nitric acid, sulfuric acid, acetic acid, oxalic acid, phosphoric acid, 5% hydrochloric acid, molten sodium, liquid hydrogen, liquid nitrogen, hydrogen sulfide, acetylene, water vapor, hydrogen, carbon dioxide gas and other environments.

  • The molding process is good, and the overall length without welding can reach 1200 mm. The products are formed at one time without cutting, the effective utilization of raw materials is high, and the material is saved to the greatest extent, especially suitable for components with large batch sizes and complex structures.


With its unique properties, stainless steel powder metallurgy sintering foam can be widely used in the pharmaceutical industry, water treatment industry, food industry, bio-engineering, chemical industry, petrochemical industry, metallurgical industry and gas purification fields. It is a new type of filtration with broad development prospects. material.

Typical uses include:

1. Impurity removal, chemical removal and fine filtration of materials in the production process of chemical raw materials.

2. Ultra-filtration for water treatment, security filtration for RO and EDI systems.

3. Clarification and filtration of beverages, fruit juice, liquor, beer, vegetable oil, mineral water, soy sauce, vinegar in food and beverage.

4. De-carbonization filtration and precision filtration of liquid products, liquid raw materials and pharmaceutical intermediates in the chemical industry, filtration and recovery of ultra-fine crystals and catalysts, precision filtration after resin adsorption and system impurity removal and filtration of thermally conductive oil and materials, and catalytic gases Purification etc.

5. Security filtration of reverse osmosis in fields such as oilfield reinjection water filtration.

6. High temperature decarburization and debais filtering in the dye industry.

7. Vapor, compressed air and catalyst filtration for gas purification.

8. Medium purification and flow limitation of pneumatic components, lubricating oil, fuel oil and hydraulic pressure system, compressed air degreasing purification, crude oil desilting filtration, nitrogen and hydrogen filtration, pure oxygen filtration, bubble generator, gas distribution of floating bed, etc.
