As a professional manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in high-performance filtration solutions. Our 260mm Diameter Dust Collector Filter Cartridge with 0.5μm PTFE Membrane delivers exceptional dust removal efficiency for industrial applications. With a rated airflow of 2000 m³/h, this cartridge is designed to optimize your dust collection system, reduce maintenance costs, and improve air quality. Trusted by clients across North America, Europe, and Asia, our product combines advanced materials with precision engineering to meet the toughest filtration demands.
The core of this filter cartridge is a PTFE (Polytetrafluoroethylene) membrane laminated onto a durable substrate. This membrane provides a surface filtration mechanism that captures fine particles as small as 0.5 microns with high efficiency, while the smooth surface allows easy pulse-jet cleaning. The pleated design increases the effective filtration area, ensuring low pressure drop and long service life. Whether you are handling cement dust, metal powders, chemical fumes, or wood chips, this cartridge offers reliable performance in pulse-jet baghouse dust collectors.
Key Features & Technical Specifications

Our filter cartridge is engineered to withstand harsh industrial environments. The PTFE membrane is chemically inert, resistant to moisture, and provides excellent dust release during pulse-jet cleaning. This results in lower cleaning frequency, reduced compressed air consumption, and extended filter life. Compared to standard cellulose or polyester cartridges, our PTFE membrane cartridge offers up to 50% longer service life and lower maintenance costs.
Advantages Over Conventional Filters
- Higher Filtration Efficiency: Captures more fine particles, helping you meet environmental regulations.
- Lower Pressure Drop: Pleated design and smooth membrane reduce airflow resistance, saving energy.
- Better Cleaning Performance: PTFE surface prevents particle adhesion, requiring less frequent cleaning cycles.
- Wider Chemical Compatibility: Resistant to acids, alkalis, and organic solvents.
- Customizable Dimensions: We offer lengths from 600mm to 1500mm, and end cap configurations to fit your existing housing.

Frequently Asked Questions
-
Q: What is the maximum temperature this filter cartridge can withstand?
A: The standard cartridge can operate continuously at temperatures up to 80°C, with surge capacity up to 100°C. For higher temperature applications, we offer special media options (e.g., PTFE/glass fiber) upon request. -
Q: Can I use this cartridge for sticky or hygroscopic dust?
A: Yes. The PTFE membrane has excellent anti-adhesion properties, making it suitable for sticky, oily, or moisture-laden dust. However, for extremely sticky materials, we recommend a pre-coating or a dedicated dust collection system. -
Q: How often should I replace the filter cartridge?
A: Replacement frequency depends on operating conditions, dust load, and cleaning efficiency. Typically, PTFE membrane cartridges last 1–2 years in moderate applications. Regular monitoring of pressure drop and air quality will help determine the optimal replacement schedule. -
Q: Is the cartridge compatible with my existing dust collector?
A: Our 260mm diameter cartridge is designed to fit most standard dust collector housings. To ensure compatibility, please provide your current cartridge dimensions (outer diameter, inner diameter, height, gasket type) and we can match or customize accordingly. -
Q: Do you offer samples for testing?
A: Yes, we provide sample cartridges for evaluation. Please contact our sales team with your testing requirements, and we will arrange shipment. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 50 pieces for most sizes, but we can accommodate smaller trial orders. For large projects, MOQ can be negotiated. -
Q: How do you package the filter cartridges for export?
A: Each cartridge is individually wrapped in a plastic bag, then packed in sturdy cardboard boxes or wooden crates, with foam spacers to prevent damage. We ship via sea from Tianjin, Qingdao, or Shanghai. -
Q: What certifications do you have?
A: Our factory operates under ISO 9001 quality management system (certification available upon request). We also comply with international standards for filtration efficiency testing. Specific product certifications are not listed unless requested.
