What are the advantages of HV-type combined high-efficiency filters?

In the assembly process, the filter paper is used incorrectly, that is, the PP paper of the medium efficiency filter (HV type) is used incorrectly as the glass fiber paper of the high-efficiency filter. What serious consequences will this cause?
Answer: First of all, during the production process, it is a deceptive act not to follow the customer's order requirements. What is more serious is that it affects the air supply volume of the entire ventilation system, which is also a direct reason for return. The medium-efficiency PP material is a medium-level filter that requires large air volume and low resistance. Under the same filtering effect and air volume, the resistance of the high-efficiency HV-type filter is equivalent to 3 times that of the medium-efficiency PP material filter. The resistance and air volume (wind speed) do not meet the customer's requirements.
How to detect the wind speed, rated air volume, initial resistance, efficiency, and other related parameters of the air filter during the test process?
Answer: The wind speed, rated air volume, resistance, and efficiency of the air filter must not leak in the surrounding frame of the test bench, and its sealing must be strict, otherwise it will affect the accuracy and authenticity of its test data. The air resistance of the tested filter at rated air volume is the initial resistance, and its face wind speed is affected by its resistance. The greater the resistance, the greater the face wind speed. The air volume and resistance are proportional.
What are the functions of the partition paper, sealant, filter material, and other related components with partitions?
Answer: The corrugated aluminum paper partition can accurately maintain the distance between the folds and maximize the use of the filter material under small resistance. In a corrosive environment, a vinyl-plated partition can be used. The edge of the partition is rolled to prevent the filter material from being damaged. The thin partition can have more folds, thereby expanding the filter material area and increasing the air volume.
The filter material is sealed with sealant in the frame to prevent side leakage around it. The sealing layer completely seals the filter material edge and the partition, that is, it seals all channels where leakage may occur.
The filter material is a high-density paper made of ultra-fine glass fiber. The filter material is folded to maximize the effective area of ​​the filter material, thereby reducing the filter material filtration rate.
Frame: (wood) 18mm~19mm thick pressed board and plywood frame are used, and the joints are connected with glue and nails to ensure its firmness. (Metal frame) It includes a variety of metal materials such as stainless steel and aluminum profiles.
The partition-free design reduces operating costs, lightweight, compact structure, and low chemical gas generation composition materials.
The partition-free and efficient design can achieve high efficiency with small resistance, thereby reducing operating costs. In particular, the designed hot melt adhesive can ensure the same pleat spacing, ensure the passage of airflow, and achieve high dust-holding capacity at the same time, making full use of the filter material on the entire depth of the filter.
What are the advantages of HV-type combined high-efficiency filters?
Answer: Large dust-holding capacity, partition-free design; solid structure to ensure good performance under turbulent conditions; high air volume type, and other characteristics. HV type filter is a high-efficiency air filter with a large load, suitable for constant airflow and variable airflow systems.
Activated carbon filter
Answer: This filter is used to remove gas, volatiles, and odor smoke, and the removal of odor increases the return air ratio in the room, thereby reducing the energy loss of heating and cooling.
