When an industrial facility operates at continuous flue gas temperatures approaching 260°C, the choice of baghouse filter media becomes a critical engineering decision rather than a routine procurement task. Woven fiberglass filter bags are specifically engineered for this class of high-temperature, high-mechanical-stress environments, and Jiangsu Aokai Environmental Technology Co., Ltd., operating under the brand Aokai Environtec, manufactures a dedicated woven fiberglass product line designed to meet these exact operating conditions.

Why Woven Fiberglass Is Selected for 260°C Applications

Woven fiberglass filter media is chosen in situations where nonwoven needle felts may not provide sufficient thermal or mechanical stability. In continuous high-temperature dust collection — such as cement kilns, power plant boilers, and municipal waste incinerators — the filter media must withstand sustained heat, resist chemical attack, and maintain structural integrity under repeated pulse-jet or reverse-air cleaning cycles. Aokai’s woven fiberglass filter bag, identified in its product catalog as AKG075WM, is built to operate continuously at 260°C with a peak temperature tolerance of 280°C, placing it among the highest temperature-rated products in Aokai’s filter bag portfolio.

Product Specifications: AKG075WM Woven Fiberglass Filter Bags

According to Aokai’s product documentation, the AKG075WM woven fiberglass filter bag is defined by the following technical characteristics:

• Temperature Resistance: 260°C continuous working temperature with a 280°C peak temperature tolerance, supporting demanding thermal cycles without loss of structural performance.
• Chemical Resistance: Strong resistance to chemical attack, suited to flue gas streams carrying acidic or corrosive constituents.
• Filtration Efficiency: Engineered for excellent fine-particle capture capability, helping facilities meet stringent particulate emission requirements.
• Mechanical Strength: Tensile strength rated at 2500 N or greater in both warp and weft directions, a property directly relevant to bags subjected to frequent mechanical or pneumatic cleaning in high-stress baghouse systems.
• Construction Details: Weight of 750 g/m² or greater, thickness of 1.0 mm ±0.2 mm, and air permeability in the range of 2 to 4 m³/m²/min.
• Post-Treatment Options: PTFE dipping and PTFE membrane lamination are available as finishing treatments, allowing the base woven fiberglass structure to be enhanced for surface filtration and easier dust cake release depending on the application.

Industry Applications

Aokai identifies the AKG075WM woven fiberglass filter bag as suitable for cement production, garbage (waste) incineration, electricity generation, coal-fired boilers, cement kiln filtration, power plants, and municipal waste incinerators. These industries share common operating challenges: elevated and sustained flue gas temperatures, abrasive or corrosive dust loads, and emission standards that continue to tighten over time. The woven construction of this product line is specifically positioned to address the mechanical demands of these settings, where continuous thermal exposure combined with cleaning-cycle stress can shorten the service life of less robust filter media.

Requesting a Quote for Woven Fiberglass Filter Bags

Facilities evaluating woven fiberglass filter bags for 260°C service can approach Aokai through its standard customer engagement process, which begins with free pre-sales consultation. This includes on-site working condition analysis and gas detection, filter media selection guidance, and product customization according to the dust collector’s specific dimensions, operating temperature profile, and emission targets. Aokai’s customization capability allows bags to be manufactured from a drawing, an existing sample, a dust collector model, support frame dimensions, or an original part number, with adjustable diameter, length, cuff type, and coating options.

Once technical requirements are confirmed, Aokai’s standard delivery timeline is 7 to 15 days depending on order quantity and customization requirements, with sample orders shipped within 24 hours. For urgent projects, priority production is available to shorten lead time further. Pricing is handled on a custom enterprise basis according to the specific bag dimensions, post-treatment requirements, and order volume, with free quotes provided as part of the pre-sales consultation process.

Manufacturing and Quality Assurance Behind the Product

Aokai Environtec’s capability to supply woven fiberglass filter bags for 260°C operating conditions is supported by in-house manufacturing of filter media, filter bags, and filter bag cages, which the company states helps ensure on-time delivery and consistent quality. The company operates an advanced testing laboratory equipped with instruments including a German FilTEq FEMA 1-AT dust filtration efficiency test system, a Netherlands Phenom Pure scanning electron microscope, an American PMI Capillary Flow Porometer CFP-1100A, a Swiss TEXTEST FX3300-IV air permeability tester, a CU-2 fiber fineness integrated analyzer, and an ESPEC high temperature testing box. These tools support the 13 core performance tests referenced in Aokai’s technical documentation, covering parameters such as fiber melting point, heat shrinkage rate, breaking strength, and air permeability.

Aokai also reports that its internal control standards are set higher than applicable national and ISO international standards, and that every custom order undergoes 100% inspection before packaging. For fiberglass-based products specifically, Aokai’s documentation notes tensile strength testing in both warp and weft directions as a standard quality checkpoint, directly relevant to the 2500 N tensile rating claimed for the AKG075WM product.

Supporting Services Beyond the Filter Bag Itself

Because high-temperature baghouse performance depends on more than the filter bag alone, Aokai Environtec also offers filter bag cages designed to match woven fiberglass bags in elevated-temperature service. The company’s cage portfolio includes galvanized treatment suitable for normal temperature conditions up to 150°C and organic silicon high-temperature spray treatment for conditions exceeding 160°C, selected according to the specific thermal profile of the installation. Cage types include round, envelope, star, spring, and U-type configurations, manufactured to fit most major dust collector OEM brands.

In addition to the filter bag and cage supply, Aokai provides lifecycle support services including filter bag failure analysis, filter media testing, baghouse inspection, defect inspection, pre-coating service, and regular inspection programs designed to predict filter bag life and reduce unplanned downtime.

Summary

For facilities requiring woven fiberglass baghouse filter bags rated for 260°C continuous operation, Aokai Environtec’s AKG075WM product line offers a defined set of technical specifications — including 280°C peak temperature tolerance, high tensile strength, and PTFE-based post-treatment options — supported by in-house manufacturing, laboratory testing, and a structured quotation process that begins with free technical consultation and working condition analysis.
