What Is a Sintered Filter Disc?
A sintered filter disc is a porous metal filtration component manufactured through a high-temperature process known as sintering. During this process, metal powders or multiple layers of wire mesh are heated below their melting point, bonding together to form a rigid and uniform pore structure.
This structure provides several advantages:
● Consistent and precise filtration
● High mechanical strength
● Resistance to pressure and temperature
● Long service life
Types of Sintered Filter Discs
To meet different industrial needs, sintered filter discs are available in several types:
■ Powder Sintered Filter Disc
Made from compressed metal powder, offering high porosity and fine filtration capability.
■ Multi-layer Sintered Wire Mesh Disc
Constructed by sintering multiple layers of woven mesh, providing excellent strength and durability.

Key Specifications of Sintered Filter Discs
1. Micron Rating (Filtration Accuracy)
Micron rating determines the particle size that can be filtered.
● 1–5 micron → ultra-fine filtration
● 10–20 micron → precision applications
● 50–100 micron → general filtration
