Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, with an annual export value exceeding US$5 Million. Our Premium High-Performance PTFE Membrane Dust Filter Bags are engineered for demanding industrial environments, delivering superior filtration efficiency and long service life. Each bag combines advanced PTFE membrane technology with robust substrate materials, ensuring reliable operation in high-temperature, corrosive, or moist conditions. Whether you need to control emissions in cement plants, steel mills, or chemical facilities, our filter bags are designed to meet the strictest environmental standards while optimizing your production costs.
Key Features & Specifications
- PTFE Membrane Surface: The microporous PTFE membrane is laminated onto a high-quality substrate (polyester, fiberglass, or aramid), providing a non-stick, easy-to-clean surface that resists particle adhesion and moisture. This results in consistently low pressure drop and high air-to-cloth ratios.
- Exceptional Filtration Efficiency: Achieves 99.99% removal of fine dust particles down to 0.3 micron, helping you comply with stringent emission regulations.
- High Temperature Resistance: Continuous operating temperature up to 260°C (500°F) with peaks up to 300°C (572°F), suitable for hot gas filtration applications.
- Chemical & Corrosion Resistance: PTFE is inert to most chemicals, making these bags ideal for acidic or alkaline dust environments.
- Customizable Dimensions: Available in a wide range of diameters (120–200 mm) and lengths (1000–8000 mm), with options for various bag top and bottom styles (e.g., snap band, cuff, strap, etc.).
- Compatible with Common Cleaning Systems: Designed for pulse-jet, reverse air, and shaker-type baghouses, ensuring easy retrofit into existing systems.
- Low Maintenance & Long Life: The robust construction and anti-stick surface reduce cleaning frequency, extend bag life, and lower your overall operating costs.

Frequently Asked Questions
Q: What is the typical lifespan of these PTFE membrane filter bags?
A: The lifespan depends on operating conditions (temperature, dust load, cleaning frequency). Under normal industrial conditions, our bags typically last 2–4 years, and in some low-abrasion applications, they can exceed 5 years.

Q: Can these bags be used in high-moisture environments?
A: Yes. The PTFE membrane is hydrophobic, so it resists moisture absorption, prevents blinding, and maintains stable filtration performance even in high-humidity or condensation-prone systems.
