PP Melt-blown Filter Cartridge

For over 16 years, our factory has specialized in manufacturing high-performance filter cartridges and filtration systems, offering cost-effective alternatives to premium brands like Pall and Hydac. Our PP (polypropylene) melt-blown filter cartridges are engineered to deliver comparable filtration efficiency, durability, and flow rates at a fraction of the price. With optimized production processes, we ensure shorter lead times without compromising quality, making us the preferred choice for clients who demand reliability, affordability, and fast delivery.

Design & Structure

Our PP melt-blown filter cartridges feature a precision-designed graded density structure, created through an advanced melt-blown process. Unlike conventional PP filters with uniform fiber distribution, our cartridges have a layered construction—progressively tighter from the outer layer to the core. This design ensures:

1. High Dirt-Holding Capacity – Captures more contaminants before clogging.

2. Optimized Flow Rate – Maintains low pressure drop even at high flow rates.

3. Depth Filtration – Traps particles throughout the entire media, not just the surface.

The cartridges are reinforced with a sturdy polypropylene core and end caps, ensuring structural integrity under varying pressure conditions. Available in multiple lengths, micron ratings (1μm to 100μm), and connection types, they are direct replacements for brand-name equivalents.

Our PP melt-blown filters match the performance of leading brands in:

1. Particle Retention – Effectively removes sediments, rust, silt, and other mechanical impurities.

2. Chemical Compatibility – Resists acids, alkalis, and most organic solvents, making them suitable for water treatment, food & beverage, pharmaceuticals, and industrial applications.

3. Temperature Resistance – Stable performance in fluids up to 80°C (176°F).

Independent tests confirm that our filters achieve >98% filtration efficiency at their rated micron size, comparable to Pall or Hydac equivalents but at a significantly lower cost.

We use 100% virgin polypropylene, ensuring no impurities or recycled materials compromise filtration quality. The melt-blown process allows for precise control of fiber density, creating a gradient structure that enhances filtration life and flow dynamics.

Key advantages of our material selection:

1. No chemical binders – Pure thermal bonding ensures no media migration.

2. High porosity – Maximizes contaminant retention while minimizing pressure drop.

3. FDA-compliant options – Available for food-grade and potable water applications.

Filtration Mechanism

PP melt-blown cartridges operate on depth filtration principles:

1. Outer Layer – Captures larger particles while allowing high flow.

2. Middle Layers – Trap mid-sized contaminants as fluid passes through.

3. Inner Core – Filters finer particles, ensuring polished output.

This multi-stage capture extends service life and reduces frequent change-outs, lowering total cost of ownership.

1. Cost Savings – Up to 40–60% cheaper than Pall/Hydac equivalents, with no sacrifice in performance.

2. Faster Delivery – Agile production allows lead times as short as 7–15 days, even for bulk orders.

3. Customization – Adaptable to OEM specifications (micron ratings, lengths, end caps, etc.).

4. Proven Reliability – Rigorous QA/QC testing (bubble point, burst pressure, flow rate validation).

As a trusted manufacturer for over 16 years, we provide high-efficiency, budget-friendly PP melt-blown cartridges that outperform generic filters and rival premium brands. Whether for industrial, commercial, or specialty applications, our solutions ensure optimal filtration, reduced downtime, and significant cost savings.
