Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 – proudly presents our Nomex Filter Sleeves for Disc Vacuum Filters. Designed to withstand continuous operating temperatures up to 250°C, these 3-meter-long sleeves offer exceptional filtration performance in demanding industrial environments. Made from high-quality Nomex meta-aramid fiber, they combine heat resistance, chemical stability, and mechanical strength to ensure reliable operation in mining, metallurgy, cement, and chemical processing plants. Our sleeves are engineered to fit standard disc vacuum filter systems, providing a tight seal and efficient cake discharge.
Key Features & Technical Specifications
- High Temperature Resistance: Continuous operation up to 250°C, with short-term peak tolerance up to 280°C – ideal for hot gas filtration and abrasive applications.
- Excellent Chemical Resistance: Resistant to most acids, alkalis, and organic solvents (except strong oxidizing agents), ensuring long service life in corrosive environments.
- Superior Mechanical Strength: High tensile strength and tear resistance prevent premature failure under vacuum pressure and mechanical stress.
- Low Pressure Drop: Optimized fiber structure allows high air permeability while maintaining fine particle capture, reducing energy consumption.
- Easy Installation & Maintenance: Pre-cut to 3-meter length with reinforced edges for quick fitting on disc sectors; can be washed and reused multiple times.
- Customizable Options: Available in different lengths, diameters, and end finishing (e.g., elastic band, hem, or metal ring) to match your specific filter system.

Detailed Product Advantages
Our Nomex filter sleeves are manufactured using a precision needle-punching process to achieve uniform fiber distribution and consistent porosity. This results in a filter medium that offers high filtration efficiency (up to 99.9% for particles above 5 µm) while maintaining low resistance to airflow. The sleeves are formed into seamless tubes, eliminating weak points at seams and extending service life. The 3-meter length is standard for most disc vacuum filter sectors, but we can produce custom lengths from 1 meter to 6 meters to accommodate non-standard equipment. Each sleeve undergoes rigorous quality control checks including dimensional accuracy, tensile strength, and thermal stability tests.
Benefits for Your Operations
- Reduced downtime: Robust construction minimizes sleeve replacement frequency.
- Energy savings: Lower pressure drop means less power required for vacuum pumps.
- Improved product quality: Consistent filtration prevents fine particles from contaminating filtrate.
- Versatility: Suitable for both wet and dry filtration processes, including hot gas filtration.
- Cost-effective: Competitive pricing without compromising on performance.

Frequently Asked Questions
-
Q: Can these sleeves be used for dust collection in high-temperature applications?
A: Yes, the Nomex material is designed for continuous operation at 250°C, making it suitable for hot gas filtration in industries such as cement, metallurgy, and waste incineration. -
Q: Are custom lengths available?
A: Absolutely. We can produce sleeves in any length from 1 to 6 meters, and also customize the diameter and end finishing to match your disc vacuum filter sectors. -
Q: How do I install the filter sleeves on a disc vacuum filter?
A: The sleeves are typically slipped over the sector and secured with an elastic band, clamp, or drawstring. Our standard sleeves include reinforced hems for easy fitting. Detailed installation instructions are provided with each order. -
Q: Can the sleeves be cleaned and reused?
A: Yes, Nomex sleeves can be cleaned using reverse air pulse, water washing, or ultrasonic cleaning, depending on the type of residue. Proper cleaning can extend the service life by several cycles. -
Q: What is the typical lifespan of these sleeves?
A: Lifespan depends on operating conditions (temperature, chemical exposure, abrasion). In normal applications such as mineral dewatering, sleeves can last 6–12 months. For high-temperature or abrasive environments, replacement may be needed sooner. We recommend periodic inspection. -
Q: Do you provide samples for testing?
A: Yes, we offer free samples of 1-meter length for evaluation. Shipping costs are negotiable. Contact us to arrange a sample order. -
Q: Are these sleeves resistant to moisture and hydrolysis?
A: Nomex has good resistance to moisture, but prolonged exposure to steam or high humidity above 200°C may cause gradual degradation. For wet filtration applications, the sleeves perform well as long as the temperature is within the specified range. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard 3-meter sleeves is 100 pieces. For custom sizes, MOQ may vary. We can accommodate small orders for trial purposes.
