Powder Sintered Filter

High-strength stainless steel powder sintered filters with uniform pore structure, excellent permeability, and outstanding corrosion resistance — ideal for high-temperature and high-pressure filtration of liquids and gases.

Stainless Steel Powder Sintered Filter Overview

Maidong stainless steel powder sintered filters are made by vacuum sintering metal powders into a rigid porous structure.
This process creates a uniform pore distribution, high mechanical strength, and stable permeability even under extreme pressure and temperature conditions.

The sintered structure provides excellent corrosion resistance and allows precise control of filtration accuracy from 0.2 μm to 100 μm.
These filters can be repeatedly cleaned by ultrasonic or chemical methods, ensuring long service life and consistent performance.

Powder sintered filters are widely used for gas and liquid purification in chemical, pharmaceutical, food & beverage, and energy industries, where durability and reliability are essential.
