Metal Pleated Filter Cartridge: The Superior Choice for High-Flow Precision Filtration
A metal pleated filter cartridge is a high-performance filtration element that utilizes special processes to form metal filter media (such as metal sintered felt or metal woven mesh) into a wave-like pleated structure. This design maximizes the effective filtration area within a limited space, making it an ideal solution for high-flow, low-pressure drop filtration applications. The core innovation lies in its pleated structure, which perfectly combines the efficiency of depth filtration with the durability of metal materials.
Large Filtration Area and Extremely Low Pressure Drop:
The pleated structure provides an effective filtration area several to dozens of times larger than that of a standard cartridge of the same size, significantly reducing fluid resistance and lowering energy consumption.
High Dirt Holding Capacity and Long Service Life:
The combination of extensive surface area and depth filtration allows it to retain more contaminants, extending replacement intervals—especially suitable for fluids with high impurity levels—and reducing maintenance costs.
High Structural Strength and Stable Performance:
The metal material (e.g., 316L stainless steel) provides exceptional mechanical strength, enabling it to withstand high pressure differentials and frequent pressure fluctuations without fiber shedding or structural collapse, unlike organic filter cartridges.
Excellent Chemical Compatibility and Temperature Resistance:
Capable of withstanding high temperatures (up to 600°C or higher) and highly corrosive media (acids, alkalis, organic solvents, etc.), making its application range far broader than that of polymer cartridges.
Reusable, Economical, and Eco-Friendly:
Can be thoroughly cleaned using methods such as ultrasonic cleaning, high-temperature baking, or reverse flushing, offering good performance recovery and multiple reuses, thereby reducing the total cost of ownership.
Thanks to its unique advantages, the metal pleated filter cartridge is widely used in fields with stringent requirements for flow rate, temperature, and durability:
Hydraulic and Lubrication Systems: Serves as a high-pressure line filter to protect precision components such as oil pumps and servo valves.
Petrochemical Industry: Used for polymer melt filtration, catalyst recovery, and process gas purification.
Pharmaceutical Industry: Sterile filtration of high-temperature sterilized air and process gases.
Food and Beverage Industry: Precision filtration of products such as beer, fruit juice, and edible oils.
Electronics Industry: Final filtration before the transfer of high-purity chemicals.
Heavy Industry and Metallurgy: Hot-rolling hydraulic systems, circulating oil systems, and blast furnace gas purification.
Consider the following factors during selection:
Filtration Rating: Choose based on the target particle size (e.g., 1μm, 5μm, 10μm).
Filter Media Type:
Metal Sintered Felt Pleated Cartridge: High filtration accuracy and dirt holding capacity, suitable for precision filtration.
Metal Woven Mesh Pleated Cartridge: Higher strength and easier cleaning, suitable for coarse filtration or applications with extreme safety requirements.
Material: 316L stainless steel is a common choice; for more corrosive media, materials like Hastelloy or Monel alloy are required.
Dimensions and Structure: Ensure the cartridge’s outer diameter, length, center tube, and sealing interface are fully compatible with your filter housing.
Operating Conditions: Clarify the maximum working pressure, pressure drop, temperature, and flow rate requirements.
