Advantages And Characteristics of Metal Powder Sintered Filter Cartridges

Advantages and Characteristics

1. Excellent Mechanical Properties:

High strength and good toughness, capable of withstanding high pressure differences and severe hydraulic impact, suitable for frequent backwashing conditions.

2. Outstanding Temperature Resistance:

Can operate stably for a long time in high or low temperature environments, without softening or creep problems common in thermoplastic filter cartridges.

3. Wide Corrosion Resistance:

By selecting appropriate metal materials according to medium characteristics, it can resist corrosion from most acids, alkalis, salts and organic solvents.

4. High Filtration Precision & Large Dirt Holding Capacity:

3D network porous structure realizes high-precision filtration and deep contaminant interception with large dirt-holding capacity.

5. Easy to Clean & Regenerate, Long Service Life:

Can be thoroughly cleaned by high-pressure backwashing, ultrasonic cleaning, chemical soaking, etc., to restore filtration performance. Service life is far longer than traditional filter materials, with low overall operating cost.

6. Good Compatibility:

No fiber shedding, no secondary pollution introduced, complying with food and pharmaceutical grade requirements.

7. Weldable:

Metal material allows welding with system pipelines to achieve leak-free connection.

Available cleaning methods:

1. Backwashing:

Use clean liquid or gas to flush from inside to outside of the cartridge. Increase pressure gently to avoid damage caused by instantaneous high-pressure impact.

2. Ultrasonic Cleaning:

Effective for strongly adherent impurities. Pay attention to power and duration to avoid damage to the microporous structure.

3. Chemical Cleaning:

Soak with suitable cleaning agents (acids, alkalis, surfactants, etc.). Pay attention to the compatibility between cleaning agent and filter material.

To avoid “air hammer” effect, pressurize slowly when starting the system, vent air from the filter chamber to prevent damage caused by instantaneous air compression and release.

Spare cartridges should be stored in a dry and clean environment with proper protection to prevent collision and contamination.
