Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in industrial filtration solutions. With over two decades of experience and an annual export value of US$5-10 million, we are proud to present our Triangular Needle Felt Filter Bag made from premium Nomex material. This filter bag is specifically engineered for high-temperature dust collection applications, offering reliable performance in demanding environments such as steel mills, cement plants, and chemical processing facilities. Its unique triangular shape maximizes filtration surface area, while the 800 g/m² felt density ensures long service life and efficient dust capture.
Key Features & Technical Specifications
- High-Temperature Resistance: Nomex fibers can withstand continuous operating temperatures up to 220°C (428°F), with peak surges up to 250°C, making them ideal for hot gas filtration.
- Triangular Shape Advantage: The triangular design provides 30-40% more filter area compared to standard round bags within the same cage volume, allowing higher air-to-cloth ratios and improved dust removal efficiency.
- Robust Construction: With a grammage of 800 g/m², the felt is dense and durable, offering excellent resistance to abrasion, chemical attack, and mechanical stress during pulse-jet cleaning cycles.
- Nomex Material Properties: Nomex (meta-aramid) inherently resists flame and hydrolysis, maintaining structural integrity in humid or acidic exhaust streams.
- Excellent Filtration Efficiency: The needle-punched felt structure achieves a fine pore distribution, capturing particles down to 1 micron with >99.9% efficiency (depending on media design).
- Customizable Dimensions: Available in various lengths, diameters, and connection styles (grommet, snap ring, cuff) to fit your existing baghouse or dust collector.

Benefits for Your Operation
- Reduced Downtime: The robust Nomex felt withstands repeated thermal cycling and pulse-jet cleaning, minimizing bag replacement frequency.
- Lower Energy Consumption: The triangular shape lowers pressure drop, allowing your fan to operate more efficiently, saving electricity costs.
- Compliance with Emission Standards: High filtration efficiency helps you meet stringent environmental regulations for particulate matter.
- Versatile Installation: Compatible with most reverse-air, pulse-jet, and shaker-type dust collectors; can be retrofitted into existing systems.
- Cost-Effective: Despite premium Nomex material, the extended service life and reduced maintenance provide a lower total cost of ownership compared to alternative high-temperature media like PTFE or fiberglass.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum operating temperature of this triangular Nomex filter bag?
A: The bag can be used continuously at temperatures up to 220°C (428°F). For short-term spikes, it can tolerate up to 250°C, but prolonged exposure above 220°C may reduce service life. -
Q: Which industries typically use this triangular filter bag?
A: It is widely used in cement kilns, steel converters, non-ferrous metal smelting, waste incineration, chemical plants, and asphalt mixing stations – anywhere hot gas streams need dust removal. -
Q: What are the advantages of the triangular shape compared to round bags?
A: The triangular design provides up to 40% more filtration area per unit volume, reduces pressure drop, and allows better cleaning during pulse-jet pulsing, leading to longer bag life. -
Q: Can I get custom sizes and connection types?
A: Yes, we offer fully customizable dimensions (length, side length) and connection options such as snap rings, grommets, cuffs, or threaded caps. Please provide your cage specifications. -
Q: How should the filter bag be cleaned? Can it be washed?
A: The bag is designed for pulse-jet cleaning. For very sticky dust, pre-coating or surface treatment (e.g., PTFE coating) is recommended. Do not wash with water unless the dust is water-soluble; consult our technical team. -
Q: What is the typical lifespan of this bag?
A: Lifespan depends on operating conditions. In standard applications with proper cleaning, the bag can last 2-4 years. Abrasive dust or chemical attack may shorten life. We recommend periodic inspection. -
Q: Do you provide samples for testing?
A: Yes, we offer sample bags (usually 1-2 pieces) for customer evaluation. Please contact our sales team to arrange a sample order with freight collect or prepaid. -
Q: Is the Nomex material resistant to acidic gases?
A: Nomex has good resistance to mild acids and hydrolysis, but strong acids like sulfuric or nitric acid can degrade the fibers. For highly acidic streams, we recommend a PTFE membrane or alternative media.
