As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998, we are proud to present our PTFE Coated Filter Element for Vacuum Feeder. This filter element is engineered to deliver exceptional performance in demanding pneumatic conveying and vacuum feeding systems, where precise filtration of fine particles is critical. With a filtration rating of 1 micron, a length of 250mm, and an outer diameter of 60mm, this element is designed to fit standard vacuum feeder housings while providing reliable separation of contaminants as small as 1 micron. Our factory, with an annual export value of US$5–10 million, has supplied high-quality filtration solutions to global markets including North America, Europe, and Asia, ensuring consistent quality and customer satisfaction.
The PTFE coating on the filter media offers excellent chemical resistance, low surface energy, and enhanced release properties, making it ideal for sticky or moist powders. This element is built to withstand harsh operating conditions, including high humidity, corrosive gases, and frequent cleaning cycles. The pleated design maximizes surface area, reducing pressure drop and extending service life. Below we detail the key features, technical specifications, and benefits that make this filter element a reliable choice for your vacuum feeder system.
Key Features and Benefits
- High Filtration Precision: 1 micron absolute rating ensures removal of fine dust, powders, and contaminants, protecting downstream equipment and product quality.
- PTFE Coated Surface: The non-stick, hydrophobic coating prevents particle adhesion, enabling easy cleaning and reducing maintenance downtime.
- Optimized Dimensions: With 250mm length and 60mm outer diameter, this element is compatible with many standard vacuum feeder models, simplifying replacement and installation.
- Durable Construction: The filter media is supported by a strong inner core and end caps, withstanding differential pressures up to 0.5 MPa (depending on design).
- Wide Chemical Compatibility: PTFE coating resists acids, alkalis, and organic solvents, making it suitable for chemical, pharmaceutical, and food processing industries.
- Low Pressure Drop: Pleated design increases filtration area, maintaining efficient airflow and reducing energy consumption in vacuum systems.
- Customizable Options: Substrate material (stainless steel, polyester, etc.) and end cap configurations are available upon request to meet specific requirements.

The PTFE coating significantly reduces the risk of blinding, especially when handling fine, hygroscopic, or electrostatic powders. For example, in the pharmaceutical industry, this filter element ensures that active pharmaceutical ingredients (APIs) are recovered without cross-contamination, while in food processing, it prevents dust explosion hazards by maintaining low static charge. The 1 micron rating captures even sub-micron particles, providing a clean air discharge and protecting vacuum pumps from abrasive wear.

Frequently Asked Questions
-
Q: What is the maximum operating temperature for this filter element?
A: The PTFE coating can withstand continuous temperatures up to 260°C, but the actual limit depends on the substrate material. For standard polyester substrate, the maximum is around 150°C. Please specify your temperature requirements when ordering. -
Q: Can this filter element be cleaned and reused?
A: Yes, the PTFE coating allows easy cleaning via backpulsing, reverse airflow, or gentle washing with water or mild solvents. The non-stick surface releases dust easily, extending the service life. -
Q: Is this filter element compatible with all vacuum feeder brands?
A: The dimensions (250mm length, 60mm OD) are common for many vacuum feeders, but we recommend checking the inner diameter and end cap type. We can customize the inner diameter, end cap style, and gasket material to fit your specific unit. -
Q: What is the filtration efficiency at 1 micron?
A: The filter element is rated at 1 micron nominal, with an efficiency typically above 99% for particles of 1 micron and larger. For absolute rating, please discuss with our technical team. -
Q: Do you offer samples for testing?
A: Yes, we provide samples upon request. A sample fee may apply for small quantities, which is refundable for bulk orders. Contact us for details. -
Q: What is the lead time for standard orders?
A: For standard sizes, lead time is typically 10–15 working days after order confirmation. Customized orders may take 15–25 working days. -
Q: How do I choose the right substrate material?
A: The choice depends on your operating temperature, chemical exposure, and mechanical strength needs. For example, stainless steel substrate is recommended for high temperature (above 200°C) or corrosive environments, while polyester is cost-effective for general applications. Our sales team can help you select the best option. -
Q: What certifications do you have?
A: Our factory follows strict quality control procedures, and we can provide a Certificate of Conformance with each shipment. Specific certifications can be discussed based on your market requirements; please contact us for more information.
