Product description
Sintered porous metal filter cartridge for extreme industrial filtration
Porous Metal Filter Cartridges are high performance filtration elements manufactured from pure sintered metal powder. The sintering process creates a rigid, self supporting structure with a controlled network of interconnected pores, delivering reliable filtration performance under extreme operating conditions.
These cartridges are designed for applications where polymer or fibre based filter media are not suitable, such as high temperature processes, aggressive chemical environments or systems requiring repeated cleaning and reuse. Their robust construction ensures long service life, stable filtration efficiency and excellent mechanical strength.
Filtration principle
Porous metal filter cartridges operate using depth filtration through a three dimensional porous metal structure. During sintering, metal powder particles are bonded together without binders or additives, forming a highly permeable matrix with defined pore size distribution.
Process fluid flows through the porous structure while particles larger than the pore openings are retained within the metal matrix.
This filtration method provides:
-
consistent and predictable particle retention
-
high permeability with low pressure drop
-
stable performance under temperature and pressure variation
-
suitability for repeated cleaning and regeneration
Construction and materials
Porous Metal Filter Cartridges are manufactured from pure sintered metal powder using a pressure free sintering process. This results in a uniform pore structure and high mechanical integrity throughout the filter element.
