By adjusting particle size and distribution, Filmedia® Everspring are capable of producing a series of powder metal filters with a wide range of filtration ratings. Powder metal filter also can be called sintered filter pipe, sintered metal powder filter element.
Description
Standard materials of powder metal felt:
1. AISI 316L and 304L stainless steel
2. Nickel based high temperature alloys, INCONEL 600/625
3. Hastelloy B,C,and X
Specification of powder metal felt:
1. Outer diameters from Φ20mm to Φ200mm
2. Length up to 1200mm, and longer filters achieved by welding
3. Filter rating from 0.5μm to 50μm
Note：For other materials and sizes, please contact us!(customizable)
Features of powder metal felt:
1. Stable dimensions.The ability to withstand alternative forces and shock resistance is superior to other metal filtration media;
2. Stable filtration efficiency and permeability;
3. Superior mechanical strength, and suitable to be used in high temperature, high pressure and strong corrosive applications;
4. Especially suitable to high temperature gas filtration;
5. Products can be produced as tubes. Connectors can be welded onto tubes.
