Product Structure
The Equivalent Pall High-Flow Filter Element features a robust design optimized for high-flow environments:
- Filter Media:
- Polypropylene (PP) or glass fiber membrane with a tapered pore structure for efficient particle removal.
- Support/Drainage Layers:
- Polypropylene (PP) or polyester/nylon for structural integrity and uniform flow distribution.
- End Caps:
- Glass-filled polypropylene (PP) or acetal for strength and chemical resistance.
- Outer Wrap:
- Polypropylene or polyolefin hotmelt for enhanced media protection.
- Coreless Design:
- Eliminates central rods, reducing pressure drop and increasing dirt-holding capacity.
- Eliminates central rods, reducing pressure drop and increasing dirt-holding capacity.

Application in Textile Industry
The Equivalent Pall High-Flow Filter Element addresses critical challenges in textile manufacturing:
- Wastewater Treatment:
- Removes dyes, particulates, and chemicals from dyeing/printing processes, enabling water reuse.
- Chemical Recovery:
- Captures valuable dyes and solvents for recycling, improving sustainability.
- Process Protection:
- Prevents machinery damage by filtering contaminants in lubricants and coolants.
Other Industrial Applications
- Reverse Osmosis Pre-Filtration:
- Protects RO membranes from particulates in water treatment plants.
- Power Generation:
- Filters boiler condensate and removes iron in power plants.
- Chemical Processing:
- Handles solvents, acids, and alkalis in refineries and petrochemical facilities.
- Food & Beverage:
- Ensures product quality by filtering edible oils, juices, and soft drinks.
Working Principle
The filter operates through a three-stage process:
- Surface Filtration:
- Large particles are trapped on the media’s surface.
- Depth Filtration:
- Smaller contaminants are captured within the porous structure of the media.
- Absolute Filtration:
- Tapered pores ensure 99.98% removal efficiency at the rated micron level.
Advantages Over Pall’s OEM
- Cost Efficiency:
- Up to 30% lower cost than Pall’s Ultipleat cartridges without compromising performance.
- Perfect Compatibility:
- Interchangeable with Pall’s systems, requiring no modifications.
- Global Compliance:
- Polypropylene media meets FDA standards for food/pharmaceutical applications.
- Reliable Performance:
- Coreless design and uniform flow distribution extend service life by up to 4x compared to conventional filters.
Conclusion
LEFILTER’s Equivalent Pall High-Flow Filter Element combines high performance, durability, and cost savings for industries ranging from textiles to water treatment. Its advanced design, easy maintenance, and compatibility make it the ideal choice for businesses seeking to optimize filtration efficiency while reducing operational costs.
