Working Principle
The filter operates through a three-stage process optimized for high-flow applications:
- Pre-Filtration:
- Nylon outer mesh removes large particulates (>50 μm).
- Depth Filtration:
- Composite media (Deflector layer + PP membrane) traps colloids and suspended solids.
- Surface Filtration:
- High-precision PP membrane ensures 99.9% removal of particles ≥70 μm.
The inside-to-outside flow design and coreless construction prevent bypass and ensure uniform flow distribution, maximizing media utilization.
Performance & Advantages
- High Flow Capacity:
- Handles 1,900 LPM, reducing cartridge count by 8x compared to standard 2.5” OD filters.
- Low Pressure Drop:
- Pleated design with 4.5 m² surface area minimizes energy loss.
- Durable Construction:
- PP composite media resists corrosion and chemical degradation.
- Cost Efficiency:
- 30% lower cost than Pall’s OEM filters without compromising performance.
- Environmental Benefits:
- Coreless design reduces waste volume by 75% compared to conventional filters.
Product Structure
The element features a spiral-wound design with the following components:
- Filtration Media:
- Polypropylene composite with tapered pore structure for high dirt-holding capacity.
- Support Layer:
- Non-woven fabric provides structural integrity.
- Flow Channels:
- Crescent-shaped pleats ensure uniform flow distribution.
- Outer Wrap:
- Polypropylene helical wrap prevents pleat collapse.
Application in Pharmaceutical Water Treatment
The Replacement Pall High-Flow Filter Element is critical for pharmaceutical applications:
- Purified Water (PW) and Water for Injection (WFI):
- Removes endotoxins, bacteria, and particulates to meet USP, EP, and JP standards.
- Process Water:
- Ensures high-quality water for formulation, cleaning, and equipment rinsing.
- Wastewater Recycling:
- Separates solvents and contaminants from wastewater, enabling safe reuse.
Other Industrial Applications
- Food & Beverage Industry:
- Clarifies juices, wines, and dairy products; removes pathogens.
- Petrochemical Industry:
- Purifies solvents, acids, and alkalis in refining processes.
- Power Generation:
- Cleans boiler feedwater and cooling systems.
- Water Treatment:
- Pre-filtration for reverse osmosis (RO) systems in desalination plants.
Conclusion
LEFILTER’s Replacement Pall High-Flow Filter Element combines advanced technology with robust construction to deliver reliable, cost-effective filtration for pharmaceutical and industrial applications. Its high flow capacity, low maintenance requirements, and environmental benefits make it the ideal choice for businesses seeking to optimize operational efficiency.
