Product Introduction
Porous metal filter tubes are engineered with a continuous spiral (helical) structure along the longitudinal axis. This innovative design enhances filtration performance, cleaning efficiency, and mechanical durability compared to conventional straight-channel filter tubes.
Constructed from high-strength metallic materials, these filters maintain superior performance under high temperature, corrosive, and abrasive conditions-making them ideal for demanding industrial applications.
Key Advantages
High Filtration Efficiency:
Porous metallic matrix captures particles within the 0.5–70 μm range, ensuring precise and stable filtration results.
Improved Backwashing Performance:
The helical ridge design creates a tortuous flow path, promoting contaminant dislodgement during reverse-flow cleaning.
Low Pressure Loss:
Optimized internal geometry minimizes flow resistance, reducing energy consumption and enhancing process efficiency.
Exceptional Durability:
Resistant to temperatures up to 500 °C, chemical corrosion, and mechanical stress, even during repeated cleaning cycles.
Long Service Life:
Robust structure allows multiple regenerations, significantly lowering long-term operating costs.
