Double-layer filter bag, have you chosen the right one?

Double-layer filter bags refer to filter bags made by connecting double layers of materials through welding or seam processing methods. Compared with conventional single-layer filter bags, double-layer filter bags have better filtering effects. In the process of designing a double-layer filter bag, the inner layer has a higher filtration accuracy, while the outer layer has a lower filtration accuracy, that is, the inner layer is coarse and the outer layer is dense. A variety of combined structures can be used to achieve more effective filtering effects. It is mainly used for filtering liquids with large impurities and uneven particle sizes.

Product features of double-layer filter bags

1. With double-layer material performance, the raw materials and sizes of filtration accuracy can be customized according to needs. The primary advantage of double-layer filter bags lies in their superior filtration capabilities. The two layers of filter media work in tandem to capture a wider range of particle sizes and contaminants. The outer layer typically acts as a pre-filter, trapping larger particles and preventing them from clogging the inner layer. The inner layer then focuses on removing finer particles and achieving the desired level of filtration. This dual-layer approach results in higher filtration efficiency compared to single-layer bags, leading to cleaner and purer filtrate.

2. Reasonable prevention of filter bag hair removal. The filter bag made of basic non-woven fabrics, with a layer of NMO mesh added to the surface, can effectively prevent hair loss during filtration and prevent leachate from being contaminated. This increased dirt-holding capacity translates to reduced maintenance costs and downtime, as filter bags need to be replaced less frequently.

3. The filtering effect is obvious. The filter bag structure with coarse inside and dense outside is adopted, with coarse filtration in the inner layer and fine filtration on the surface. Although double-layer filter bags may have a slightly higher initial cost compared to single-layer bags, their long-term cost-effectiveness makes them an attractive option. Their extended lifespan, reduced maintenance requirements, and improved filtration performance contribute to lower overall filtration costs. By reducing the frequency of filter bag changes and ensuring optimal filtration, double-layer bags offer a cost-efficient solution for various filtration applications.

4. The filtering accuracy of the double-layer filter bag ranges from 0.1 to 500 microns, and its materials are classified into polyester, polypropylene, polyester, etc. While double-layer filter bags offer higher filtration efficiency, they are also designed to maintain a good flow rate. The structure of the two layers is optimized to allow liquid to pass through with minimal resistance. This ensures that the filtration process does not significantly impede the flow of liquid, making double-layer bags suitable for applications that require a consistent and adequate flow rate.

5. Acid resistance and high fiber mechanical strength: Due to its acid resistance and high fiber mechanical strength, the double-layer filter bag can be used for a long time in a harsh working environment while maintaining high filtration performance.

6. Reusable: The double-layer filter bag can be used repeatedly, which reduces the cost of use. It also meets environmental protection requirements, reduces the use of disposable filter materials, and is beneficial to environmental protection. The pre-filtration provided by the outer layer protects the inner layer from premature clogging, allowing it to function effectively for a longer period. This extended lifespan reduces the overall cost of filtration by minimizing the number of filter bag replacements required.
