The 75μm SS 304 stainless steel porous sintered wire mesh filter cartridge is a high-performance filtration element engineered for demanding industrial applications, including liquid purification and solid-liquid separation processes. Manufactured from premium SS 304 stainless steel wire mesh, the cartridge is produced through a precision vacuum sintering process that fuses multiple layers of wire mesh at elevated temperatures, forming a uniform and well-controlled three-dimensional porous structure. This design ensures both high filtration accuracy and excellent compressive strength. The cartridge features a composite construction consisting of five sintered wire mesh layers plus an additional support layer, which not only guarantees consistent filtration performance and uniform pore distribution but also substantially enhances the structural rigidity and fatigue resistance of the filter element.

The cartridge is equipped with a flange-type connection interface with a flange diameter of 140mm, facilitating rapid and secure sealing connections with standard industrial piping and equipment, thereby reducing installation and maintenance complexity. With an outer diameter of 130mm and an effective length of 500mm, this dimensional configuration balances high-flow processing capacity with space-efficient installation requirements. Whether employed as a standalone filter unit or as a core component within multi-stage filtration systems, this cartridge consistently delivers reliable, stable, and repeatable filtration performance across a broad spectrum of industries, including petrochemical, food and beverage, pharmaceutical, and environmental water treatment.

Products Features

1. Multi-Layer Composite Sintered Structure Combining Strength and Precision

The cartridge is constructed from five layers of stainless steel wire mesh with graded pore sizes, arranged in a gradient configuration and metallurgically bonded through high-temperature vacuum sintering into a monolithic structure. An additional support layer is integrated on the outer side to enhance compressive strength and impact resistance. This multi-layer composite design enables precise particle retention at a nominal rating of 75μm, while effectively preventing localized damage or media migration commonly observed in single-layer mesh filters, thereby substantially extending service life.

2. Excellent Corrosion Resistance and Thermal Stability
SS 304 stainless steel offers outstanding resistance to acid and alkali corrosion, as well as high-temperature oxidation, ensuring stable long-term operation in media with a wide pH range and under elevated temperature conditions. The cartridge maintains structural integrity and consistent filtration performance at operating temperatures up to 500°C, making it suitable for demanding applications involving organic solvents, superheated steam, and aggressive chemicals.

3. Low Pressure Drop and High Throughput Capacity

The sintered wire mesh structure features a high open-area ratio and smooth flow channels, resulting in an exceptionally low initial pressure drop across the filter element. This characteristic enables stable filtration efficiency even under high-flow-rate conditions. The low pressure drop directly reduces pumping energy consumption and helps maintain system pressure stability, making the cartridge particularly suitable for continuous production and high-capacity recirculating filtration systems.

4. Resistance to Thermal Shock and Structural Integrity under Cycling Conditions

The metallurgically bonded multi-layer construction exhibits excellent resistance to thermal shock, enabling the cartridge to withstand rapid temperature fluctuations-such as those encountered during steam sterilization, hot-water backwashing, or sudden process temperature swings-without suffering from delamination, pore distortion, or mechanical failure. This thermal cycling stability ensures reliable long-term performance in processes characterized by intermittent high-temperature operation and frequent thermal cleaning cycles, significantly reducing the risk of premature filter failure.
