Introduction
Compared with traditional filtration materials such as paper,
cotton, PP, PE, PES, and PTFE, metal powder sintered porous materials offer outstanding advantages. They feature excellent permeability,
uniform and controllable pore size, high filtration accuracy, good
mechanical strength, wear resistance, and thermal stability.
Sintered filters maintain their structural integrity under high
temperatures and pressures, provide long service life, and can be reused multiple times after cleaning or backflushing. These properties make them ideal
for applications requiring reliable filtration, separation, and gas or liquid purification in challenging environments.
