Product Instruction
Cartridge filter (also named precision filter), the housing usually is made of stainless steel. The filter uses cartridge as the filtering medium. The cartridge can be: Melt Blow Cartridge/String Wound Cartridge/PP Folded Cartridge/ Nylon Membrane Cartridge/PES Cartridge/PTFE Cartridge . A different filtering element is selected according to different filtered material and the designed technology to reach the quality requirements. The filter precision range: 0.1 ~60 ; the model includes 10 inches, 20 inches, 30 inches and 40 inches; Connection ports: plug port (222 and 226) and flat port.
Working Principle
The liquid will be fed into the filter from the inlet, then go through the cartridge from external side to inner side, then
discharge from outlet. While the filtering, impurities will be trapped by the cartridge, so that realize filtering effect.
Features
• Even distributed apertures ensure high filtering precision
• High cleanliness of cartridge material makes no secondary pollution
• Good chemical stability: Resists alkaline, acid and chemical solvents
• Cost saving, low running cost, easy clean and the cartridge can be changed
Titanium rod filter 316L SHC
The shell is made of 316L stainless steel, and the inner filter element is titanium filter tube.
High temperature, high pressure, strong acid, strong alkali corrosion, filter element can be recycled. The machine adopts powder metallurgy method to process the metallurgical powder through high temperature sintering to make the hollow filter pipe, which is widely used in the solid liquid separation of food and beverage, pharmaceutical, chemical and other industries, especially in the pharmaceutical industry is suitable for decarburization in the production line of large infusion injection.
