Sintered metal mesh filter cartridge is the cylindrical filter element made of sintered wire mesh. These filter cartridges mostly use standard 5 layer sintered wire mesh Type A as the filter media. Type B all square weave sintered wire mesh is also used in cartridges which need high permeability and flow rating.
Advantage of sintered mesh filter cartridges comparing to wire mesh filter
Comparing to non-metallic and ordinary wire mesh filter cartridges, sintered metal mesh filter cartridge is superior in:
- fixed and stable pore size under high temperature and pressure
- suitable for temperature applications higher than 300 degree Celsius
- washable and reusable
- all welded structure, no risk of failure of spot welding or adhesive
- self-support, easy to form cartridge

As the mechanism of the sintered wire mesh is stop and restrain the impurities in the working fluid, there are chances that the impurities accumulated and form the filter cake. The filter cake can increase the filtering accuracy at certain degree before the cake is cleaned or removed by backwashing or offline cleaning.

Sintered metal mesh filter cartridges
Sintered metal mesh filter cartridge is suitable for applications of micron level filtration and separation. Such as particle candle filter for chemical, pharmaceutical, oil & gas, petrochemical; strainer for food & beverage, fuel, hydraulic.
