Forms and Structures of Sintered Metal Filter Elements
Sintered metal filter panels can be further fabricated into a wide range of filter elements to meet different application requirements. Through precision moulding combined with high-temperature sintering, these panels are formed into various structures such as filter discs, filter cartridges, laminates, tubes, baskets, cone filters, cup filters, cap filters, and filter plates, ensuring stable performance and dimensional accuracy.
Sintered filter discs are available in multiple configurations, including round, oval, annular, split, and integral designs. They are capable of operating in extreme temperature environments ranging from -200°C to 600°C, making them suitable for drying and filtration processes. The filtration accuracy typically covers a range of 2 to 300 microns.
