Metalman PSM CSM Filter Cartridge


The best solution for filtering liquids in high temperature and pressure conditions

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 Metalman PSM/CSM Filter Cartridge?

Metalman pleated stainless steel mesh cartridge is made of woven stainless steel mesh, which can be made into a pleated structure and cylindrical structure. The pleated structure gives it a large filter area and therefore a better performance in terms of lifetime and flow rate. This is the most general stainless steel cartridge.

Metalman PSM/CSM filter cartridge has excellent temperature and pressure resistance.  It is the best choice for filtering liquids in high temperature and pressure situations because its pore size is regular and each junction between the grids is made by sintering and will not change under high pressure.

Brother Filtration manufactures Metalman PSM/CSM filter cartridges in all stainless steel construction, with inner reinforcing part and optional external mesh coverage. The PSM/CSM filter cartridge is strong enough to withstand high pressure and high temperature without fiber migration.

Additionally, the PSM/CSM filter cartridge is re-washable and can be back flushing in high-pressure conditions, which means it is an environmentally-friendly product and reduces users’ operation costs at the same time.


Brother Filtration always produces high-quality products, the same as our Metalman PSM/CSM. We adopt high-standard stainless steel with a great designed structure to make filters have better performance.

  • All stainless steel construction
  • Inner reinforcing
  • External mesh coverage can be added
  • Uniform pore size
  • Resistance to corrosion, high pressure, and extreme temperature
  • Excellent mechanical strength
