Sintered Powder Filter Element Separates Particulate Impurities in Liquids & Gases

Sintered powder filter element is made of metal powder as raw material without adding adhesive. Formed under isostatic cool pressing and sintered with high temperature vacuum. The pore size and distribution of the element can be adjusted by selecting the metal powder particle size and process parameters. The pore structure, material composition, pressure strength, and other characteristics of different filtration materials are used to develop filtration products that are ultimately suitable for the user's needs.

Working Principle

Sintered powder filter element can realize micron-level precision filtration, can separate solid particles in the liquid, gas impurities, when the fluid passes through a certain degree of accuracy of the element, the impurities are blocked on the surface of the element to form a filter cake, pure fluid through the element outflow, so that the contaminated live impurity-containing fluids filtration to the state of the normal production required to ensure that downstream devices to obtain a pure product to live to protect the normal operation of the equipment.

Different from the non-metallic sintered element is that when the surface of the sintered power filter element of the filter cake reaches a certain thickness, because of its high strength performance characteristics, so through a certain reverse pressure on the element to backwash or blowback method to clean the element, the element can be used again.
