Metalman PSF Cartridge


Pleated stainless steel felt filter cartridge with a large filtration area

What is a metal filter cartridge?

Metal filter cartridges are used in instances where conventional filters are insufficient. This situation may be caused by high temperatures, high pressures, corrosive chemicals, or the necessity to clean and reuse the cartridge. Titanium is occasionally utilized in addition to 316/304 stainless steel as the primary material of the metal filter cartridge.

Brother Filtration introduced a new range named Metalman in the summer of 2022. To meet all kinds of unique filtration requirements, The Metalman comes with a number of unusual metal cartridges. We use titanium in addition to premium stainless steel, and we think these new goods will capture your attention.

What is the Metalman PSF cartridge?

Metalman stainless steel felt cartridge with a large filtration area by folding and forming can achieve absolute filtration accuracy. Stainless steel fiber sintered felt is a porous depth type filter material made of stainless steel fiber sintered at high temperatures.

Brother Filtration manufactures Metalman PSF cartridges in all stainless steel construction, so it has wide chemical compatibility. Also, it can withstand high temperatures and resist corrosion and oxidation. In addition, the PSF filter has a multi-layer structure, which contains a reinforcing layer, protection layer, and main filtration layer, which results in a strong construction that can withstand high pressure.

Stainless steel fibers that have been sintered to provide a high porosity depth filtration material are used to create the distinctive stainless steel sintered felt. A graduated pore size from coarse (upstream) to fine (downstream) is one of the properties of PSF Filter Cartridges, which results in a higher dirt holding capacity and longer service life.

With all characteristics mentioned above, the PSF filter cartridge is a perfect solution for steam filtration or liquids with high viscosities such as sugars and syrups.
