Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer since 1998 — proudly presents our 0.5 Micron 304SS Filter Element specifically designed for vacuum feeders used in pharmaceutical powder transfer. With over two decades of experience in wire mesh and filtration solutions, we deliver precision-engineered components that ensure product purity, system efficiency, and regulatory compliance. Our filter elements are manufactured under strict quality control, supporting export volumes of US$5–10 million annually to markets across North America, Europe, Asia, and more.
This filter element is the heart of any vacuum conveying system handling fine pharmaceutical powders. It captures particles as small as 0.5 micron, preventing cross-contamination and protecting downstream equipment. The 304 stainless steel construction offers excellent corrosion resistance and durability, making it ideal for repeated cleaning (CIP/SIP) cycles. Available in customizable dimensions and connection styles, our filter elements integrate seamlessly into existing vacuum feeder setups.
Key Features & Technical Specifications
- High Filtration Efficiency: 0.5 micron absolute rating captures fine dust and bacteria, ensuring clean powder transfer and meeting GMP requirements.
- Premium Material: Made from 304 stainless steel (SS304) with optional electropolished surface for smooth release of powder and easy cleaning.
- Pleated Design: Maximizes filtration area (up to 3–5 times more surface area than plain mesh), reducing pressure drop and extending service life.
- Robust Construction: Welded seams and reinforced end caps withstand high vacuum pressure (up to -0.8 bar) and mechanical shocks.
- Customizable Connections: Available with flanges, tri-clamps, threaded ends, or quick-connect fittings to match your vacuum feeder model.
- Reusable & Cleanable: Suitable for backwashing, ultrasonic cleaning, or autoclaving — reduces replacement costs and waste.
- Wide Temperature Range: Operates from -20°C to 120°C (with appropriate sealing gaskets), ideal for hot air drying or steam sterilization.

- Cost-Effective: 304SS durability means thousands of cleaning cycles; lower total cost of ownership compared to disposable filters.
- Seamless Integration: Customizable dimensions and connections allow direct replacement of most OEM filter elements without modification.
- Improved Flow: High surface area ensures low pressure drop, maintaining vacuum feeder efficiency even with fine powders.
Frequently Asked Questions
Q1: Can this filter element be used for other materials besides pharmaceutical powders?
A: Yes, it is suitable for any fine powder or granular material that requires 0.5 micron filtration, such as food ingredients, chemicals, and pigments. However, for pharmaceutical use, we recommend ensuring material compatibility and cleaning validation.
Q2: What is the typical lifespan of this filter element?
A: Lifespan depends on operating conditions, cleaning frequency, and powder characteristics. Under normal pharmaceutical environments, with proper cleaning, it can last 1–3 years. Regular inspection for clogging or damage is recommended.
Q3: How do I clean the filter element?
A: It can be cleaned by backwashing with compressed air or water, ultrasonic cleaning, or autoclaving. For pharmaceutical applications, we recommend validated CIP/SIP procedures. Avoid using abrasive brushes that may damage the mesh.
Q4: Do you offer custom sizes for non-standard vacuum feeders?
A: Absolutely. We can customize outer diameter, length, connection type, and even filtration rating (e.g., 0.3, 1.0 micron). Please provide your existing filter dimensions or a drawing for a quotation.
Q5: Is this filter element compatible with high-temperature drying processes?
A: Yes, with appropriate sealing materials (e.g., silicone or Viton), it can withstand temperatures up to 120°C. For higher temperatures, we can discuss 316L stainless steel options.
Q6: Can you provide samples for testing before bulk order?
A: Yes, we offer sample orders with short lead times. Sample cost is negotiable, and we can provide a certification of material and filtration performance.
Q7: What packaging do you use for export shipment?
A: Each filter element is individually wrapped in anti-static plastic, placed in a sturdy carton with foam padding, and packed in export wooden cases. We ensure safe delivery to ports like Tianjin, Qingdao, Shanghai, and Foshan.
Q8: Do you have any quality certifications?
A: Our factory operates under an internal quality management system. We can provide material test certificates, dimensional inspection reports, and filtration efficiency test data upon request. Specific third-party certifications can be discussed based on your requirements.
