XVGL series box type V-shaped high-efficiency filter element

The XVGL series box type V-shaped high-efficiency filter element is a core filter element developed specifically for high air volume air purification scenarios. It relies on the V-shaped dense pleated structure to significantly increase the filtration area, meeting the high air volume and low resistance purification needs of industrial ventilation, clean spaces, and other scenarios without increasing too much installation space. It provides stable and efficient filtration core support for various centralized air supply systems.

The XVGL series box type V-shaped high-efficiency filter element adopts ultra-fine glass fiber non partition filter material, which folds the filter material into multiple compact V-shaped structures and is embedded in a rigid support frame as a whole. Metal protective nets are installed on both sides to prevent deformation and damage of the filter material under high air volume impact. The sealing part is seamlessly sealed with polyurethane or hot melt adhesive to effectively prevent air leakage risk. The filtration efficiency covers all grades from H11 to H14, and the interception efficiency of 0.3μm particles can reach up to 99.995%. The initial resistance can be controlled within 220Pa at rated air volume, and the dust holding capacity is much higher than that of flat high-efficiency filter element s with the same windward area. The overall mechanical strength can adapt to turbulent wind speed conditions, and bidirectional installation can also maintain stable filtration performance.

The XVGL series box type V-shaped high-efficiency filter element is suitable for various ventilation and purification scenarios, and can be used in industrial clean room centralized air supply systems, commercial central air conditioning end filtration, variable air volume ventilation and air conditioning units. It can also meet the requirements of high humidity ventilation systems, airport and high-end office building air supply purification, museum and library air purification. At the same time, it is suitable for purification systems with limited installation space and high air volume requirements, replacing traditional flat filter element s to achieve better purification performance.

The core advantages of the XVGL series box type V-shaped high-efficiency filter element are very prominent. Firstly, it has excellent filtration efficiency and air volume balance performance. The V-shaped dense pleated structure doubles the unfolding area of the filter material in a limited space, and can maintain low initial resistance even under high air volume operation, reducing the energy consumption of the system during long-term operation; Secondly, it has a large dust holding capacity and a long service life. The filter material is evenly distributed, and the resistance increases slowly during the dust accumulation process. Compared with ordinary flat filter element s, it can significantly extend the replacement cycle and reduce operation and maintenance costs; Thirdly, it has strong adaptability to working conditions, with a sturdy structural design that can withstand turbulent flow impacts, supports bidirectional installation, and is suitable for complex operating environments such as high humidity and variable air volume; Fourthly, it has wide adaptability, and the standard size can directly match the mainstream box type filter housing without the need to modify the original installation frame.

The common problems encountered in the practical use of XVGL series box type V-shaped high-efficiency filter element s can be solved through corresponding solutions. Firstly, the pressure difference of the newly installed filter element far exceeds the design value after operation, often due to the actual air volume of the system far exceeding the rated air volume of the filter element . Therefore, it is necessary to check the system air volume parameters and replace the filter element corresponding to the rated air volume to avoid long-term operation beyond the working conditions; Secondly, there may be edge air leakage during use, which is often due to the sealing surface of the filter element not being tightly fitted during installation. It is necessary to check the flatness of the installation frame and adjust the clamping device to ensure that there is no gap between the filter element and the sealing part of the frame; Thirdly, the service life of the filter element is relatively short, mostly due to insufficient pre filtration level at the front end. A large amount of large particle impurities directly enter the high-efficiency filter element. It is recommended to install a medium efficiency filter of F7-F9 level at the front end to extend the saturation cycle of the filter element.
