Stainless Steel Sintered Fiber Felt Filter Cartridge
The stainless steel sintered fiber felt filter cartridge is engineered for high-temperature and high-pressure filtration applications where strength, durability, and filtration efficiency are critical requirements.
This cartridge features a stainless steel inner support core and sintered stainless steel fiber felt media, delivering exceptional mechanical stability and consistent pore structure. An optional outer support cage can be integrated to enhance pressure resistance and extend service life in demanding operating environments.
With its all-metal construction, the filter cartridge provides outstanding resistance to high temperature, high pressure, corrosion, and thermal shock, making it ideal for continuous operation and repeated cleaning cycles.
