Product Description

Product Description

Woven Fiberglass Filter Bag

Yangxin Environmental's High-Performance Fiberglass Filter Bags are engineered for efficient particulate control under high-temperature conditions. Backed by decades of experience in industrial flue gas treatment and advanced membrane technology, our filter bags ensure low emissions, long service life, and stable performance — helping industries such as cement and chemicals meet stringent environmental regulations with reduced operating costs.

Reliable Dust Emission Control

Unlike conventional filter bags, Yangxin's fiberglass filter bags feature specialized membrane coatings and seam-sealing technology that effectively eliminate stitch-hole leakage. Even under continuous pulse cleaning, the filter bags maintain exceptional filtration efficiency of up to 99.99%, reducing baseline emission levels and ensuring consistent compliance throughout the filter bag's lifecycle.

Key Technical Advantages

High-Temperature Durability: Constructed with premium fiberglass media and PTFE membranes, our filter bags perform reliably in high-temperature and chemically aggressive environments.

Advanced Seam-Sealing: Fully enclosed thermal-sealed seams eliminate leakage at stitch lines — ideal for applications that demand near-zero particle escape.

Extended Lifespan: Designed to withstand mechanical stress from frequent pulse cleaning, the membrane remains intact without cracking or peeling, typically delivering a service life of 3+ years under standard operating conditions.

Application Industries

Cement Industry

Chemical Industry

With tightening global regulations, Yangxin's fiberglass filter bags help cement plants maintain full production capacity while meeting environmental standards. Their structural integrity and filtration performance remain stable even under high dust loading and intensive cleaning cycles, minimizing the risk of shutdown due to non-compliance.

In chemical processing, fine and corrosive particulates, as well as valuable powders, place high demands on filter media. Yangxin fiberglass filter bags are ideal for capturing high-value particles, controlling emissions in contamination-sensitive applications, and ensuring reliability in aggressive gas streams.

Carbon Black Industry

Organosilicon Industry

Reliable Filtration Under High Dust Loads and Abrasive Conditions

The carbon black manufacturing process generates extremely fine, high-temperature, and highly abrasive particulate matter, placing exceptional demands on filter bag performance. Yangxin Environmental's fiberglass filter bags with PTFE membrane and seam-sealed construction are specifically designed to handle such severe environments.

The organosilicon industry involves complex chemical reactions that often release sticky, low-flowability particulate matter along with acidic or corrosive off-gases. Conventional filter bags may clog, degrade, or fail to meet emission requirements under these challenging conditions.

Yangxin Environmental's high-performance fiberglass filter bags are engineered to provide exceptional chemical resistance, low differential pressure, and high filtration stability even in low-dust-flow, high-condensation-risk environments.
