Description
Stainless steel wire mesh filter bags are high-performance industrial filtration components engineered for demanding liquid filtration applications. Installed within a filter basket—similar to conventional fiber filter bags—they effectively capture and separate solid contaminants from process liquids. Their key advantage lies in the use of stainless steel wire mesh as the filtration medium. This structure delivers exceptional mechanical strength, outstanding dimensional stability, and superior resistance to deformation under pressure. As a result, these filter bags can operate under higher differential pressures (typically 0.15 MPa, up to 0.20 MPa), enabling longer service life, extended replacement intervals, and significantly reduced overall operating costs.
- The non-deformable SUS304 or SUS316 stainless steel is spun into a mesh according to the specified specifications, and then becomes a monofilament mesh after heat setting.
- High strength and will not deform due to changes in pressure.
- The monofilament weave creates a smooth surface that is easy to clean and can be used over and over again.
Product Features
- High quality stainless steel material, deep filtering.
- The bag ring made of stainless steel can withstand higher temperatures and is not easy to break.
- The bag body is edged with corrosion-resistant material and tightly sewn with multiple threads.
