PP Melt-blown Filter Cartridge

For over 16 years, our factory has specialized in manufacturing high-performance PP (polypropylene) melt-blown filter cartridges as affordable alternatives to premium brands like Pall and Hydac. Our filters deliver comparable filtration efficiency, durability, and flow rates at a fraction of the cost, while maintaining shorter lead times to meet urgent production demands.

In industries dealing with chemical liquids—such as electroplating solutions, solvents, paints, coatings, and detergents—maintaining liquid purity is critical. Contaminants like particulates, sediments, and undissolved solids can compromise product quality, damage equipment, and disrupt production. Our PP melt-blown filter cartridges provide an economical yet high-performance solution for these challenges.

PP melt-blown filter cartridges are widely used in chemical filtration due to their unique structure and material advantages:

1. High Dirt-Holding Capacity & Gradual Filtration

Unlike surface filters (e.g., pleated or mesh filters), PP melt-blown cartridges have a depth filtration structure with a gradient pore size (typically from outer larger pores to inner smaller pores). This design traps particles throughout the media, maximizing dirt retention while reducing clogging.

Ideal for filtering viscous liquids like paints, resins, and electroplating baths, where fine debris must be removed without frequent cartridge replacements.

2. Chemical Compatibility

Polypropylene is resistant to a wide range of chemicals, including acids, alkalis, and organic solvents, making it suitable for aggressive fluids like electroplating solutions and industrial cleaners.

3. High Flow Rates & Low Pressure Drop

Our optimized manufacturing process ensures large filtration area and uniform fiber distribution, enabling high flow rates with minimal pressure drop—critical for maintaining process efficiency in high-throughput applications.

4. Cost-Effective Replacement

Compared to branded filters, our PP cartridges offer similar or better performance at 30-50% lower cost, reducing operational expenses without sacrificing quality.

1. Electroplating & Surface Treatment

In electroplating, impurities in the plating bath (e.g., dust, metal oxides, or organic residues) can cause coating defects, poor adhesion, or uneven deposition. Our PP melt-blown filters:

Remove particles down to 1–20 microns (depending on grade).

Extend bath life by preventing contamination buildup.

Compatible with acidic/alkaline solutions (e.g., nickel, copper, and chromium plating baths).

2. Paints, Coatings, & Inks

Contaminants in paint and ink formulations lead to surface imperfections, nozzle clogging in spray systems, or inconsistent coloration. Our filters:

Capture fillers, agglomerated pigments, and gel particles.

Ensure smooth application and reduce waste in automotive, furniture, and industrial coating processes.

3. Solvents & Chemical Processing

Pharmaceuticals, agrochemicals, and specialty chemicals require ultra-clean solvents. Our cartridges:

Purify acetone, alcohols, ketones, and other organic solvents.

Protect downstream equipment (e.g., pumps, membranes, or reactors).

4. Detergents & Cleaning Agents

Solid residues in liquid detergents can clog dispensers or leave streaks. Our filters:

Remove undissolved salts, silica, or processing aids.

Improve product clarity and consistency.

While Pall, Hydac, and other premium brands dominate the market, our PP melt-blown cartridges stand out by offering:

✅ Same/Better Filtration Performance – Rigorous testing ensures micron ratings match OEM specifications.

✅ 30-50% Cost Savings – Direct manufacturing (no middlemen) cuts expenses.

✅ Faster Delivery – Large-scale production capacity ensures 5–10-day lead times (vs. 3–6 weeks for some brands).

✅ Customization – Available in multiple lengths, micron ratings, and end-cap configurations (e.g., 222/226, threaded, or flanged).

For chemical manufacturers seeking reliable, budget-friendly filtration, our PP melt-blown filter cartridges provide an unbeatable balance of performance, price, and speed. By choosing our filters as alternatives to Pall or Hydac, you gain:

✔ Longer service life with high dirt-holding capacity.

✔ Stable production with consistent liquid purity.

✔ Reduced operational costs without quality compromises.
