Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted partner in filtration solutions since 1998. Our PE Coated Filter Cartridge for Pharmaceutical Industry 0.2 Micron Sterile Filtration is engineered to meet the highest standards of purity and performance. With a robust manufacturing background and a strong export track record of US$5–10 million annually, we deliver reliable filtration products that safeguard your critical processes. This cartridge features a specialized PE coating that enhances chemical resistance and dirt-holding capacity, making it ideal for sterile applications in pharmaceutical, biotech, and food & beverage industries.
Key Features & Benefits:
- 0.2 Micron Absolute Filtration: Achieves sterile-grade removal of bacteria, yeast, and particulate contaminants, ensuring product safety and compliance with pharmacopoeia standards.
- PE Coated Media: The polyethylene coating provides a smooth, non-fiber-releasing surface that minimizes extractables and enhances flow rate without compromising retention.
- High Dirt-Holding Capacity: The graded density structure of the filter media allows for efficient particle capture throughout the depth, extending service life and reducing replacement frequency.
- Chemical Compatibility: Resistant to a wide range of acids, alkalis, and organic solvents commonly used in pharmaceutical manufacturing, including cleaning agents and sanitizers.
- Thermal Stability: Operates effectively at temperatures up to 80°C (with appropriate sealing materials), suitable for hot water sanitization and steam sterilizable (up to 121°C for 30 minutes, optional).
- Multiple End Configurations: Available with DOE, 222/226 O-rings, or 215 flat gaskets to fit standard housings from all major manufacturers.

Detailed Technical Advantages: Our PE coated filter cartridges are manufactured using a melt-blown process with a patented PE coating technology. This creates a gradient pore structure that captures particles from 0.2 micron to larger sizes, ensuring high retention efficiency (>99.9%) while maintaining low pressure drop. The coating also prevents fiber migration, which is critical for sterile applications where any shedding could contaminate the product. The cartridges are available in standard lengths of 10, 20, 30, and 40 inches, and can be customized to specific dimensions upon request. Each cartridge is individually tested for integrity before packaging, ensuring consistent performance. The non-woven support and drainage layers provide mechanical strength without adding extractables, making them suitable for use in parenteral drug manufacturing, buffer filtration, and final rinse water systems.

Frequently Asked Questions (FAQ):
-
Q: What is the difference between a standard PP filter cartridge and a PE coated one?
A: The PE coating adds a thin layer of polyethylene to the polypropylene media, which reduces fiber shedding, improves chemical resistance, and enhances dirt-holding capacity. It is particularly beneficial for pharmaceutical sterile filtration where low extractables and high purity are required. -
Q: Can this cartridge be steam sterilized?
A: Yes, with optional sealing materials (e.g., silicone or Viton) and a stainless steel core, the cartridge can withstand up to 121°C for 30 minutes. Please specify your requirement when ordering. -
Q: Are these cartridges validated for bacterial retention?
A: Our 0.2 micron cartridges are designed for absolute removal of bacteria such as Brevundimonas diminuta. We can provide retention test data upon request, and custom validation services are available for qualified customers. -
Q: What lengths and diameters are available?
A: Standard lengths are 10, 20, 30, and 40 inches, with outer diameter of 2.5 inches. Custom diameters (e.g., 2.75 or 4.5 inches) can be manufactured. Please contact us for non-standard sizes. -
Q: How do I select the correct O-ring material?
A: O-ring selection depends on the chemical compatibility and temperature. Silicone (FDA grade) is common for water and steam; EPDM for general chemicals; Viton for aggressive solvents. We recommend providing your fluid composition for optimal selection. -
Q: Do you offer samples for testing before bulk purchase?
A: Yes, we provide sample cartridges for evaluation. Please contact our sales team with your application details, and we’ll arrange a sample shipment. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes and materials, lead time is 15–20 days after confirmation. Custom orders may require 25–30 days. We can expedite based on your urgency. -
Q: How do you ensure product quality and consistency?
A: Each cartridge undergoes bubble point testing and visual inspection before packaging. Our manufacturing process is monitored under a quality management system. We also maintain batch traceability records.
