As a manufacturer with over 25 years of experience in wire mesh and filtration products, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our 316L Stainless Steel Filter Bag for Bag Filter Systems, specifically engineered for the pharmaceutical industry. This filter bag combines high-precision 0.5 micron filtration with the corrosion resistance of 316L stainless steel, ensuring product purity and process reliability. Designed to meet the stringent demands of pharmaceutical manufacturing, our filter bag offers a robust, reusable, and easy-to-clean solution for critical filtration applications.
Key Features & Technical Specifications:
- Material: Made from 316L stainless steel, providing excellent resistance to acids, alkalis, and high temperatures, ideal for pharmaceutical environments.
- Filtration Precision: 0.5 micron absolute filtration rating ensures removal of fine particles, meeting strict purity standards.
- Reusable: Can be cleaned and reused multiple times, reducing operational costs and waste compared to disposable filter bags.
- High Flow Rate: Large surface area design minimizes pressure drop while maintaining high throughput.
- Easy Installation: Compatible with standard bag filter housings; available with various connection types (flange, clamp, etc.) to fit your system.
- Customizable: Size, gasket material, and surface finish can be tailored to your specific requirements.
- Non-Contaminating: 316L stainless steel does not leach harmful substances, ensuring product integrity.

Advantages for Pharmaceutical Applications:
- Compliance: The 316L stainless steel construction meets FDA and GMP guidelines for contact with pharmaceutical products.
- Durability: Withstands repeated sterilization cycles (autoclave, CIP/SIP) without degradation.
- Cost-Effective: Long service life reduces replacement frequency and maintenance costs.
- Versatility: Suitable for liquid filtration in API synthesis, intermediate purification, final product polishing, and clean-in-place systems.
- Eco-Friendly: Reusable design minimizes waste generation compared to disposable filters.
How It Works: The filter bag is installed inside a bag filter housing. Liquid flows from inside the bag to the outside, trapping particles on the inner surface. The 0.5 micron mesh ensures that even sub-micron particles are retained, providing a high level of clarity. After use, the bag can be cleaned by backwashing or ultrasonic cleaning, restoring its filtration performance.
Quality Assurance: Every filter bag is manufactured using precision-woven 316L stainless steel wire mesh, with strict quality control on mesh count and aperture size. We offer samples for testing before bulk orders are placed.

Frequently Asked Questions (FAQ)
Q1: What is the difference between 316L and 304 stainless steel filter bags?
A: 316L stainless steel contains molybdenum, providing superior corrosion resistance against chlorides, acids, and high-temperature environments. It is preferred for pharmaceutical applications where purity and chemical resistance are critical.
Q2: Can this filter bag be used for sterile filtration?
A: While the 0.5 micron rating removes particles, it does not guarantee sterility (which typically requires 0.2 micron or smaller). However, 316L stainless steel can withstand autoclaving and SIP processes, making it suitable for pre-filtration steps in sterile lines.
Q3: How do I clean the filter bag?
A: Common methods include backwashing with clean water or solvent, ultrasonic cleaning, or chemical flushing. The bag can be reused multiple times if properly cleaned. We recommend testing cleaning cycles to determine optimal frequency.
Q4: What sizes are available?
A: Standard sizes include diameters from 4 to 10 inches and lengths from 14 to 36 inches. Custom sizes are available upon request. Please provide your housing specifications for a tailored solution.
Q5: Do you offer samples before bulk order?
A: Yes, we provide samples for testing. Please contact us with your requirements, and we will arrange sample shipment.
Q6: Is this filter bag food-grade?
A: 316L stainless steel is food-grade and complies with FDA regulations for contact with food and pharmaceutical products. However, always verify gasket material compatibility with your specific application.
Q7: What is the maximum pressure drop across the filter bag?
A: The pressure drop depends on flow rate, viscosity, and particle loading. Typically, we recommend not exceeding 2.5 bar (36 psi) to avoid damage. Our technical team can provide guidance based on your operating conditions.
Q8: Can I use this filter bag with aggressive solvents?
A: 316L stainless steel is resistant to many organic solvents, acids, and alkalis. However, please check the compatibility of the gasket material. For aggressive chemicals, PTFE or Viton gaskets are recommended.
