How to choose a high-efficiency filter with partitions based on air volume and installation size?
When choosing a high-efficiency filter with partitions, you should not just look at the filter size, but also consider factors such as installation size, air volume, filtration efficiency, initial resistance, and equipment structure .
For applications such as clean rooms, air-conditioning boxes, and air supply systems, selection can usually be made by ' first determining the installation size, then matching the air volume and filtration level, and finally checking the resistance and system capabilities .'
1. First determine the filter installation size
First, you need to confirm the filter installation space reserved by the equipment, including:
The overall dimensions of the partitioned high-efficiency filter need to match the installation frame. If the equipment has been designed, priority should be given to selecting the corresponding specifications according to the existing installation dimensions.
If it is a new clean room or air treatment equipment, the number and specifications of filters can be determined based on the design air volume.
2. Determine the number of filters according to the system air volume
The air volume processed by a single filter needs to match the actual operating air volume.
For example, if an air treatment system requires a larger filtered air volume, the system requirements can be met by increasing the number of filters, using larger size filters, or adjusting the combination of filters.
When actually selecting a model, it is not recommended to simply pursue a higher air volume per unit. It is also necessary to comprehensively consider the filter resistance and the static pressure capacity of the system fan.
3. Select filtration efficiency according to cleanliness level
The high-efficiency filter with partitions can select the corresponding filtration efficiency level according to the requirements of the clean environment.
Common applications include:
Application environment |
Selection points of concern |
clean room |
Cleanliness level, air supply volume, filtration efficiency |
air conditioning box |
Air volume, resistance, filter size |
laboratory |
Filtration efficiency, sealing performance |
Electronic manufacturing |
Air cleanliness, particle control |
pharmaceutical environment |
Cleanliness requirements, filtration efficiency, sealing method |
Semiconductor related environment |
High cleanliness requirements, system air volume, filtration efficiency |
For applications with higher cleanliness requirements, the HEPA filter grade needs to be determined based on the specific cleanliness level, particle control requirements, and system design.
4. Pay attention to the initial resistance of the filter
The initial resistance of the filter will affect the operating status of the fan and the energy consumption of the air handling system.
At the same filtration efficiency level, the filter material structure, filter area, surface wind speed and filter design will all affect the resistance.
Therefore, when choosing a high-efficiency filter with partitions, you should also pay attention to:
Rated air volume + initial resistance + filtration efficiency
Rather than just comparing the overall dimensions of the filters.
5. Determine the filter structure according to the actual application
The partition structure supports and separates the filter material through partitions, so that the filter material can form a larger effective filtration area and is suitable for a variety of air treatment equipment.
For large air handling systems, the filter combination can be designed based on the internal space of the equipment, system air volume, and filter arrangement.
Aili Industrial can match the specifications according to the filter size, target air volume, efficiency level, installation method and application environment provided by the customer , and can also provide corresponding filter configuration suggestions based on the equipment structure.
3. Selection parameters of high-efficiency filter with partitions

4. Aili industrial partitioned high-efficiency filter
Aili Industry has long been engaged in the R&D and production of clean air treatment equipment and filtration products. It can provide high-efficiency filter products according to the design requirements of different clean spaces and air treatment equipment.
In actual projects, high-efficiency filters are not independently selected, but also need to fans, air conditioning boxes, FFU, clean room air supply systems, and filter installation structures .be matched with
Therefore, if the customer has determined the equipment size or system air volume, they can provide:
Filter size + air volume + efficiency requirements + usage environment
Aili Industrial can assist in determining the corresponding high-efficiency filter specifications.
