What are the main applications for Glass Fiber Needle-Punched Felt Filter Bags?

These filter bags are primarily used in industries such as cement, steel, and power generation, where they are tasked with capturing dust and particulates to control emissions and maintain air quality. Their high-temperature and chemical resistance make them ideal for processes involving high heat and exposure to aggressive chemicals.

How do I determine the appropriate filter bag size for my system?

The selection of filter bag size should be based on the specific requirements of your filtration system, including the volume of air to be filtered, the type and size of particles to be captured, and the available space within the filter housing. Standard sizes like 130mm diameter and 2000mm length are designed to fit a broad range of systems, but custom sizes can also be manufactured to meet specific needs.

What maintenance is required for these filter bags?

Regular inspection and cleaning are essential to maintain the efficiency and longevity of Glass Fiber Needle-Punched Felt Filter Bags. Depending on the operating conditions, bags may need to be cleaned more frequently to prevent clogging. It's also important to inspect the bags for wear and tear, especially in areas exposed to high temperatures or chemicals, and replace them as necessary to avoid filter failures.

Why Choose Glass Fiber Needle-Punched Felt Filter Bags?

The glass fiber needle-punched felt produced by our company is made from alkali-free glass fiber staple fibers and base fabric conforming to the national standard 12.5# yarn, and is manufactured using a single-step double-faced forming process. It is a filter material specifically designed for high-temperature applications.

Glass fiber needle-punched felt is a high-temperature filtration material with a rational structure and excellent performance. It possesses the advantages of glass fiber fabrics, including high-temperature resistance, corrosion resistance, dimensional stability, minimal elongation and shrinkage, and high strength. The fibers in the felt layer form a three-dimensional microporous structure, resulting in high porosity and low gas filtration resistance, making it a high-speed, high-efficiency high-temperature filtration material. Compared to other high-temperature synthetic fiber felts, it is more affordable and withstands higher temperatures; however, its operating resistance is higher than that of general synthetic fiber high-temperature filter media, and its filtration precision is slightly lower.

This product can be widely used for high-temperature flue gas filtration in industrial furnaces and kilns in the chemical, steel, metallurgy, carbon black, power generation, and cement industries, and is compatible with various baghouse dust collectors that use pulse-jet or high-speed reverse-jet cleaning systems.

Key Technical Attributes
