Stainless Steel Pleated Filter Cartridge

The STP filter is made of special stainless steel fiber filter felt and mesh, folded into an M-shaped multi-pleat structure, and prepared by argon arc welding.

Resistant acid and alkali, corrosion, high temperature, high pressure. Low resistance and fast flow rate.

Suitable for the filtration of corrosive liquids or gases under high temperature and high pressure conditions.

Different from stainless steel sintered filters, this pleated stainless steel filter excels in targeted scenarios where high stability and efficient purification are required. It is widely applied in high-pressure steam sterilization filtration in pharmaceutical and food industries, precision pre-filtration of high-viscosity lubricating oil and resin in mechanical manufacturing, and deep impurity removal of acidic/alkaline media in petrochemical production. Besides, it perfectly fits high-temperature corrosive gas treatment in metallurgy and high-pressure liquid purification in water treatment systems, which are hard for sintered filters to adapt to stably with long-term high flow rate.

    Features and Benefits

    ◆Extremely robust construction, high mechanical strength

    ◆Ideal for aggressive solvents, viscous and hot solutions

    ◆Backwashable and cleaned by chemical solvent, hot water, steam, long service life

    ◆Pleated Cartridge provides higher filtration area

    ◆Removal rating from 5 to 100 microns
