The 226 plug-in acid-alkali resistant pure titanium sintered filter cartridge is made from industrial high-purity titanium powder (purity ≥99.4%), processed via sieving, cold isostatic pressing, and sintered under high temperature and high vacuum, forming a uniform-structured porous material with narrow pore size distribution. It offers high porosity, low filtration resistance, high permeability, high temperature resistance (≤280 °C), acid and alkali corrosion resistance, and oxidation resistance, with zero particle shedding, meeting GMP sanitary requirements for food and pharmaceutical industries. It supports both pressure and suction filtration, features low differential pressure, high flow capacity, strong anti-microbial properties, and overall seamless construction up to 1000 mm long. It is regenerable online, easy to clean, and lasts several times longer than conventional membrane cartridges. Widely used in pharmaceutical, water treatment, food, bioengineering, chemical, petrochemical, metallurgy, and gas purification industries.
