Cartridge Micro Filter could filter particles and bacteria bigger than 0.1μm in liquid or gas. It has the advantages of high filtration accuracy, fast transition speed, less adsorption, no media shedding, acid and alkali corrosion resistance, and convenient operation. Now, it plays an important role in pharmaceutical, chemical, beverage, beer, water processing, and other industries.



  • First, clean the filters, and install the filter element and housing correctly.

  • Before starting the machine, check if the system is running correctly. The parts should be tightly connected. And the valves should be closed.

  • Slowly open the inlet valve before starting the machine, exhaust the air, and then open the outlet valve for filtration.

  • If it is found that the filter pressure difference is more than 0.1Mpa or the flow rate drops significantly, it indicates that most of the pores of the filter element have been blocked. It is recommended to clean or replace the filter element.


The stainless steel cartridge micro filter has a filter element and a stainless steel housing. Filter element could be made of PP or PES. The filter element and housing is clamped or union connected. It is convenient for assembling, maintenance, and cleaning. The inner surface of the filter is mirror polished (roughness Ra≤0.28μm). There is no dead leg. And it meets the requirements of "FDA" and "GMP"

Sunthai supplies food grade stainless steel cartridge filter. Food grade must meet FDA standards. The filter material is SS304/SS316L, both inside and outside are finely polished, and there are no dead legs. It has small size, light weight, convenient use, large filtering area, low clogging rate, fast filtering speed, no pollution, high thermal dilute stability and high chemical stability.


  • It's necessary to maintain the cartridge micro filter.

  • The most important part of the precision micro filter is filter element. The filter element is made of special materials. As it could be easily damaged, special protection is required.

  • When it is found that the filter pressure difference is bigger or the flow rate drops significantly, you should clean or replace the filter element.

  • When you are cleaning the filter element, you should be careful. If it is deformed or damaged, it need to be replaced immediately. That's because it could not filter as well as before. 

  • Some precision filter elements cannot be used repeatedly, such as bag filter elements and polypropylene filter elements.
