String Wound Filter Cartridge 5 Micron

 

Our string wound filter cartridge 5 microns are precisely wound to effectively capture suspended solids such as fine silt, settled minerals, rust specks and scale particles down to 5 microns, providing essential protection for sensitive downstream equipment and processes. Ideal for demanding pre-treatment applications where steady flow and high dirt loading are critical.

1️⃣ Graded-Density Filtration

Optimized wound structure for progressive depth filtration and maximum dirt-holding capacity.

 

2️⃣ Consistent Performance Guarantee

Rigorous process controls ensure uniform yarn tension, spacing, and density across every string wound cartridge for predictable 5-micron retention and flow characteristics.

 

3️⃣ High-Purity, Inert Construction

Virgin food-grade PP ensures no leaching, minimal extractables, and broad chemical compatibility for process stream integrity.

 

4️⃣ Structural Integrity

Robust polypropylene core and securely bonded end caps withstand operational pressures, preventing bypass or collapse.

 

 

The primary main applications of string wound filter cartridge 5 micron:

• Pre-filtration for RO systems
• Industrial process water
• Wastewater treatment
• Beverage and food & beverage clarification
• Chemical and petrochemical process streams
• Paints, coatings, and inks
• Power generation boiler feedwater
• Mineral processing and mining fluids
• Compressed air and gas polishing

 

 

✅ Incoming Material Inspection: Strict controls on raw yarn and core materials.

✅ In-Process Controls: Automated monitoring of winding tension, density, and dimensions during production.

✅ Performance Testing: Batch testing for:

• Bubble Point Test: Verifies pore size integrity and largest pore.
• Dirt Holding Capacity (DHC): Measures total particulate captured before terminal pressure drop.
• Flow Rate & Pressure Drop: Ensures performance meets specifications.
• Extractables Testing: Validates material purity for critical applications (e.g., food/beverage, pharma).

✅ Dimensional Checks: Guarantees compatibility with standard and OEM housings.

✅ Burst Strength Testing: Confirms structural integrity under pressure.
