Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of expertise in wire mesh and filtration solutions. Since 1998, we have been dedicated to producing high-quality industrial filtration products, exporting to markets across North America, South America, Europe, Asia, and Oceania with an annual export value exceeding US$5 million. Our Disc Vacuum Filter Cloth Bags, 50 Micron, PTFE Coated, Anti-Static, 130°C Continuous are engineered to deliver reliable performance in demanding vacuum filtration applications. Combining advanced PTFE coating technology with anti-static properties, these bags offer superior chemical resistance, high-temperature stability, and precise particle separation, making them an ideal choice for industries such as mining, chemical processing, pharmaceuticals, and wastewater treatment.
Each disc filter cloth bag is manufactured from premium polyester substrate, evenly coated with a durable PTFE layer that enhances non-stick characteristics and extends service life. The 50-micron filtration rating ensures consistent removal of fine particles while maintaining excellent flow rates. Our anti-static design prevents static charge buildup, reducing fire and explosion risks in hazardous environments. With a continuous operating temperature of 130°C, these bags withstand hot process streams without degradation. Whether you need standard sizes or custom dimensions, our factory in Hengshui, Hebei, China is equipped to meet your specific requirements.
Key Features & Advantages
- PTFE Coated Surface: Provides excellent non-stick properties, easy cake release, and resistance to acids, alkalis, and organic solvents.
- Anti-Static Performance: Conductive fibers or treatment dissipate static electricity, enhancing safety in explosive atmospheres.
- High-Temperature Tolerance: Continuous operation up to 130°C (short-term peaks up to 150°C) without loss of filtration efficiency.
- Precise 50 Micron Filtration: Effectively captures particles in the fine range while maintaining low pressure drop.
- Robust Construction: Double stitching and reinforced edges prevent tearing under high vacuum pressure.
- Customizable Dimensions: Available in various disc diameters, thicknesses, and sealing options to fit your filter press or disc filter.
- Long Service Life: PTFE coating reduces wear and chemical attack, minimizing replacement frequency and downtime.

Frequently Asked Questions
-
Q: What is the maximum temperature these bags can withstand?
A: The continuous operating temperature is 130°C, with short-term peaks up to 150°C. For higher temperature applications, we can recommend alternative materials such as PTFE felt or Nomex. -
Q: Are these bags suitable for food-grade applications?
A: The PTFE coating is chemically inert and FDA-compliant for indirect food contact. However, please specify your application so we can confirm if any additional certifications are required. -
Q: Can I get custom disc diameters or thicknesses?
A: Yes, we offer customization for disc diameter, edge finishing, and grommet placement. Minimum order quantities may apply for non-standard sizes. -
Q: How do the anti-static properties work?
A: The bags incorporate conductive fibers or a surface treatment that dissipates static electricity, keeping surface resistance below 10^8 Ω/sq. This meets typical anti-static standards for explosive environments. -
Q: What is the typical lifespan of these filter cloth bags?
A: Lifespan depends on operating conditions such as temperature, chemical exposure, and mechanical stress. In typical mineral processing or chemical filtration, they can last 6–12 months. Our PTFE coating significantly extends life compared to uncoated polyester. -
Q: Do you provide samples for testing?
A: Yes, we offer sample bags in common sizes. Please contact us with your filter disc dimensions, and we can arrange a sample for evaluation. -
Q: What is the lead time for bulk orders?
A: For standard sizes, lead time is typically 15–20 working days. Custom orders may require 25–30 working days. We ship via sea freight from Tianjin, Qingdao, or other major ports. -
Q: Can these bags be used in acidic or alkaline environments?
A: Yes, the PTFE coating provides excellent resistance to most acids, alkalis, and organic solvents. However, we recommend checking compatibility with highly concentrated oxidizing agents at elevated temperatures.
