As a professional manufacturer with over 25 years of experience in wire mesh and filtration products, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) proudly introduces our Aramid Triangular Needle Felt Filter Bag – a high-performance solution specifically engineered for coal mill dust collection systems. With an annual export value of US$5–10 million and serving markets across North America, Europe, Southeast Asia, and beyond, we understand the rigorous demands of industrial filtration. This filter bag combines the exceptional heat resistance of aramid fibers with an innovative triangular cross-section design, delivering superior dust cake release, reduced pressure drop, and extended service life even under extreme conditions up to 200°C continuous operation. The built-in anti-static properties ensure safe handling in explosive environments, making it an ideal choice for coal grinding, cement, steel, and power generation industries.

Key Features & Technical Specifications

High Temperature Resistance: Continuous operating temperature up to 200°C (peak 220°C), suitable for coal mill exhaust gas where temperatures can exceed 180°C.
Triangular Needle Felt Structure: The unique triangular fiber cross-section increases the specific surface area by 30% compared to round fibers, enhancing filtration efficiency and dust cake release.
Anti-static Performance: Conductive fibers (e.g., stainless steel or carbon) are blended into the felt to prevent static charge buildup, reducing the risk of sparks and explosions in coal dust environments.
High Gram Weight (500 g/m²): Provides excellent mechanical strength and dimensional stability, resisting abrasion and flex fatigue during pulse-jet cleaning.
Chemical Resistance: Aramid fibers offer good resistance to acids, alkalis, and organic solvents commonly found in industrial flue gases.
Customizable Dimensions: Available in various lengths, diameters, and cuff styles to fit any baghouse or dust collector.
Easy Installation & Maintenance: Lightweight yet durable, with reinforced sewing for long-lasting performance.

Parameter	Value
Continuous Operating Temperature	200°C (392°F)
Peak Temperature (short-term)	220°C (428°F)
Gram Weight	500 g/m² ± 5%
Fiber Type	Aramid (Meta-aramid / Para-aramid blend)
Anti-static Enhancement	Integral conductive fibers (≤10⁶ Ω surface resistance)
Filtration Efficiency	≥99.9% (for particles >1 µm, depending on media design)
Air Permeability	8–15 m³/m²/min @ 200 Pa (customizable)
Available Sizes	Diameter: 120–300 mm; Length: 1000–10000 mm (custom)

Why Choose Our Aramid Triangular Filter Bag?

Improved Dust Release: The triangular fiber shape reduces particle adhesion, allowing efficient pulse-jet cleaning and lower residual pressure drop.
Longer Service Life: Aramid’s inherent thermal stability and abrasion resistance extend bag life by 30–50% compared to standard polyester or polyimide bags in coal mill applications.
Enhanced Safety: Anti-static design meets international standards for explosive dust environments (e.g., ATEX, NFPA – optional upon request).
Energy Savings: Lower pressure drop means reduced fan energy consumption, lowering operational costs.
Proven Performance: Successfully installed in hundreds of coal-fired power plants, cement kilns, and steel mills worldwide.

Our factory in Hengshui, Hebei, China, has been supplying high-quality filtration products since 1998. With an annual export value exceeding US$5 million and a global footprint covering North America, South America, Europe, Asia, Africa, and Oceania, we have the capacity and expertise to deliver consistent, reliable products. We use advanced needle-punching machinery and strict quality control processes to ensure each filter bag meets the required specifications.

Frequently Asked Questions (FAQ)

Q: What is the maximum continuous operating temperature of this filter bag?
A: The bag is designed for continuous operation at 200°C (392°F) and can withstand short-term peaks up to 220°C (428°F). For applications exceeding these limits, please contact us for alternative materials.
Q: How does the triangular fiber shape improve filtration performance?
A: Triangular fibers provide a larger surface area per unit volume, which enhances particle capture efficiency and facilitates better dust cake release during cleaning. This results in lower pressure drop and longer filter life.
Q: Is the anti-static feature effective in coal dust environments?
A: Yes, the bag incorporates conductive fibers that dissipate static charges, reducing the risk of spark ignition. The surface resistance is typically ≤10⁶ ohms, which meets common safety standards for explosive dust atmospheres.
Q: Can I get custom sizes for my baghouse?
A: Absolutely. We offer fully customizable dimensions – diameter, length, cuff style, and sewing reinforcements – to match your existing filter bags. Simply provide your requirements, and we will produce accordingly.
Q: What is the typical delivery time for large orders?
A: For standard sizes, lead time is 15–25 working days. Custom orders may require 20–35 working days depending on quantity and complexity. We ship from our ports in Tianjin, Qingdao, Shanghai, or Foshan.
Q: Does this bag require any special installation or handling?
A: No special tools are needed. The bag is designed to be installed like any conventional filter bag. However, we recommend wearing gloves to avoid contamination, and ensure the bag is not dragged over sharp edges to prevent damage.
Q: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects under normal operating conditions. Extended warranty options are available upon request.
Q: Can you provide samples for testing before bulk order?
A: Yes, we provide sample bags (shipping cost applies) for evaluation. Please contact our sales team to discuss the sample size and testing conditions.
