Introduction
For over 16 years, our factory has specialized in manufacturing high-quality, affordable filter cartridges as direct replacements for premium brands like Pall and Hydac. Our PP (polypropylene) melt-blown filter cartridges are engineered to deliver exceptional filtration efficiency, durability, and flow rates—making them the ideal choice for medium and large ultra-pure water systems. These filters serve as critical pre-filtration components, protecting downstream equipment by removing particulate contaminants and ensuring water cleanliness.
Unlike standard filters, our large-flow PP melt-blown cartridges provide high dirt-holding capacity, consistent filtration performance, and extended service life—all at a fraction of the cost of branded alternatives. With streamlined production and rapid delivery, we meet the demands of industries requiring reliable, high-volume filtration solutions without compromising quality or lead times.
Essential
Ultra-pure water (UPW) systems are widely used in semiconductor manufacturing, pharmaceuticals, power plants, and laboratory applications, where even microscopic impurities can disrupt processes or damage sensitive equipment. The pre-filtration stage is crucial because it:
1. Removes sediment, rust, colloids, and organic particles (typically 1–20 microns).
2. Prevents fouling of downstream RO membranes, ion-exchange resins, and polishing filters.
3. Reduces maintenance costs and extends the lifespan of high-purity filtration systems.
Our PP melt-blown cartridges excel in this role due to their graded-density structure, which traps contaminants throughout the depth of the filter media rather than just on the surface. This design maximizes dirt-holding capacity while maintaining low pressure drop, ensuring efficient flow rates even in high-capacity systems.
Advantages
1. Performance Comparable to Premium Brands at a Lower Cost
Filtration Efficiency: Our filters achieve ≥99% particle retention at their rated micron sizes (1, 5, 10, 20 microns), matching the performance of leading brands.
Material Quality: We use 100% virgin polypropylene, ensuring no fiber shedding or extractables that could contaminate ultra-pure water.
Chemical Compatibility: Resistant to acids, alkalis, and most solvents, making them suitable for aggressive fluid applications.
2. Optimized for High Flow Rates & Large Systems
Low Pressure Drop: The graded-pore structure allows for higher flow rates with minimal energy consumption.
High Dirt Loading Capacity: Depth filtration design captures more contaminants before clogging, reducing change-out frequency.
Support for Large Housings: Available in standard sizes (10", 20", 30", 40") and custom lengths to fit multi-cartridge housings.
3. Fast Production & Reliable Supply
Short Lead Times: Unlike branded filters with long delivery cycles, we maintain ready stock and rapid production turnarounds.
Customization Options: Adjustments in micron rating, length, end caps, and O-ring materials (e.g., EPDM, silicone) are available.
4. Strict Quality Control
ISO 9001-certified manufacturing with rigorous testing (bubble point, particulate shedding, flow rate validation).
Compliance with NSF, FDA, and RoHS standards for safety in sensitive applications.
Applications in Ultra-Pure Water Systems
Our PP melt-blown filters are widely used in:
1. Semiconductor & Electronics Manufacturing
Protects DI water systems from particulates that could cause defects in wafer production.
2. Pharmaceutical & Biotech
Pre-filtration for WFI (Water for Injection) and purified water systems.
3. Power Plants (Steam Generation)
Safeguards boiler feed water to prevent scaling and corrosion.
4. Food & Beverage Processing
Removes suspended solids in bottling and CIP (clean-in-place) systems.
