As a leading manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory has been dedicated to producing high-performance filtration solutions. Our PTFE Coated Filter Bags for Disc Vacuum Filters are engineered to meet the demanding requirements of industrial solid-liquid separation. With 50 micron precision, chemical resistance, and anti-static properties, these bags are crafted from 100% virgin material to ensure long service life and consistent filtration efficiency. Whether you are processing minerals, chemicals, or wastewater, our filter bags deliver reliable performance under harsh conditions.
Leveraging over two decades of expertise and an annual export value exceeding US$5 million, we supply to markets across North America, Europe, Southeast Asia, and beyond. Our products are trusted by global clients for their exceptional durability, superior release characteristics, and compliance with international standards. Below, we detail the key features and technical specifications that set our PTFE coated filter bags apart.
Key Features & Benefits
- PTFE Coating Technology – Provides excellent non-stick surface, reducing cake adhesion and improving release efficiency. The coating also enhances chemical resistance against acids, alkalis, and organic solvents.
- 50 Micron Filtration Precision – Optimized for fine particle capture while maintaining high flow rates. Suitable for applications requiring clear filtrate and low pressure drop.
- Anti-Static Property – Integrated conductive fibers or surface treatment prevent electrostatic buildup, reducing fire and explosion risks in combustible dust environments.
- 100% Virgin Material – No recycled fibers; ensures consistent strength, dimensional stability, and longer service life compared to blended or inferior materials.
- Customizable Design – Available in various shapes (sector, flat, etc.) and dimensions to fit different disc vacuum filter models. Grommets, hemming, and edge reinforcements can be added upon request.
- High Temperature Resistance – Continuous operation up to 260°C (500°F) makes them suitable for hot gas filtration and high-temperature slurry processes.
- Excellent Mechanical Strength – High tensile and burst strength withstands repeated flexing and vacuum forces during filter cycles.

Frequently Asked Questions (FAQ)
-
What is the typical lifespan of these PTFE coated filter bags?
Lifespan depends on operating conditions such as temperature, chemical exposure, and mechanical stress. Under normal disc vacuum filter conditions, our bags can last 6–12 months or longer. The anti-stick coating helps reduce wear from cake removal. -
Can the filter bags be customized to fit my specific disc filter model?
Absolutely. We offer custom shapes, sizes, and attachment methods (e.g., grommets, snaps, or sleeves). Please provide your filter dimensions or a drawing, and we will produce accordingly. -
Are these bags suitable for highly acidic or alkaline slurries?
Yes, the PTFE coating provides excellent chemical resistance across a wide pH range (2–14). However, we recommend testing under your specific chemical conditions to ensure compatibility, especially for concentrated oxidizers. -
How does the anti-static property work?
Conductive fibers or a carbon-based coating are integrated into the fabric, providing a surface resistance ≤10⁶ Ω. This prevents static charge accumulation, reducing the risk of sparks in combustible dust environments. -
What is the maximum temperature these bags can withstand?
Continuous operation up to 260°C (500°F) with surges up to 280°C. For higher temperature requirements, we can recommend alternative media such as PTFE felt or PPS. -
Do you provide samples for testing before bulk order?
Yes, we offer free samples (courier cost paid by buyer) for evaluation. Production samples can be made to your exact specifications for qualification. -
What is the packaging method for export?
Each bag is individually packed in poly bags, then packed in cartons or on pallets with waterproof wrapping. We ensure safe transportation and can also customize packaging per your request. -
What is the minimum order quantity (MOQ)?
MOQ is typically 50 pieces for standard sizes. For custom sizes, MOQ may vary. We welcome small trial orders for new customers.
