The melt filter cartridge manufacturer offers elements made of stainless steel fiber sintered felt processed with pleating technology to form a multilayer graded structure from coarse to fine. They feature high porosity, high dirt holding capacity, high filtration precision, high temperature resistance (-200 to 600 °C), corrosion resistance, high mechanical strength, and excellent processability. As cleanable and reusable filter media, they have a long service life, especially suitable for viscous liquids and high-temperature gas filtration. They offer large filtration area, low pressure drop, support chemical cleaning, thermal regeneration, and ultrasonic cleaning, and are widely used in polymer melt filtration, oil-water separation, high-temperature gas purification, pharmaceutical media filtration, and separation processes in the petrochemical industry.
