304 Sintered Stainless Steel Wire Mesh Filter Element is a high-precision industrial filter made of high-purity 304 stainless steel sintered wire mesh and manufactured through a full argon arc welding process. It features an outer diameter of 60 mm, a length of 508 mm, and a filtration accuracy of 75 microns. With an inside-out filtration direction, it effectively removes solid particles from fluids to ensure downstream medium cleanliness.

The filter element adopts a 222/fin standard connection and is supplied with a silicone O-ring for each unit, providing excellent sealing performance. The full argon arc welding process results in full, uniform, aesthetically pleasing, and strong weld seams, enabling the product to maintain outstanding durability and structural stability under demanding working conditions. It is suitable for precision filtration in various harsh environments.

This filter element is compact, easy to install, and offers good corrosion resistance and temperature resistance due to its 304 stainless steel sintered mesh, allowing long-term stable operation. The inside-out filtration direction facilitates easy cleaning and maintenance, prevents rapid differential pressure rise caused by external clogging, and extends the service life of the element. Each filter element is strictly tested before delivery to ensure that filtration accuracy and sealing performance meet standard requirements, making it an economical and reliable industrial filtration component.

Products Features

75-Micron High Precision for Broad Particle Control: With a filtration accuracy of 75 microns, this filter element effectively removes medium-sized solid particles from fluids, making it suitable for systems such as hydraulic oils, coolants, and chemical media where particle control is critical, balancing flow capacity and interception efficiency.

Full Argon Arc Welded Structure with Strong and Uniform Seams: Manufactured using a full argon arc welding process, the welds are uniform, full, and free from cold welds or leaks. The structure offers high mechanical strength, capable of withstanding high differential pressures and backwashing operations, avoiding the failure risks of traditional glued elements in high-temperature or corrosive environments.

222/fin Standard Connection with Silicone O-Ring for Reliable Sealing: The 222/fin interface is compatible with various standard filter housings in the industry. Each filter element comes with a heat-resistant and aging-resistant silicone O-ring, ensuring no bypass leakage during inside-out filtration and enhancing system safety.

Compact 60mm × 508mm Size for Strong Adaptability: The standardized dimensions of 60 mm outer diameter and 508 mm length allow multiple units to be installed in parallel within limited spaces. They are suitable for standard filter vessels or custom filter housings, reducing retrofit costs and improving equipment compatibility.

applications

Employed in natural gas pipeline systems to eliminate entrained dust and in produced water treatment trains to capture solid particulates ahead of reinjection. This helps safeguard downstream pumps, control valves, and flow metering devices against erosion and premature failure induced by abrasive particles.

Chemical and Fine Chemical Production: Suitable for filtering high-viscosity resins, solvents, and catalyst slurries to remove by-product particles or unreacted solid raw materials, improving product purity and reducing downstream distillation or crystallization loads.

Water Treatment and Wastewater Reuse: Applied as a pre-filtration element in industrial cooling water systems, RO pretreatment stages, or membrane protection filters to capture suspended solids, rust fragments, and biological debris above 75 microns, extending the cleaning cycles of downstream membrane elements.

Hydraulic and Lubrication Systems: Used in large hydraulic power units, steam turbine lubrication systems, and paper machine lubrication circuits to filter wear particles and external contaminants in oil, maintaining oil cleanliness levels and reducing abnormal wear of bearings and gears.

Food & Beverage Industry: Employed in syrup clarification, beer rough filtration, and plant extract purification to remove pulp, fiber particles, and protein agglomerates. The filter element meets food-grade material requirements, supports CIP cleaning, and reduces replacement frequency.

Pharmaceutical and Bio-fermentation: Used in the pretreatment stage of fermentation broth to intercept mycelium, solid culture medium residues, and other particles above 75 microns, protecting downstream ceramic membranes or tubular centrifuges, reducing clogging risks in high-value equipment, and improving batch production stability.
