The same project can evaluate the use of different chemical filter media, but their respective goals, combination sequence, environmental suitability and maintenance methods should be clearly defined. Putting different media together does not mean that the efficiency and capacity of the mixed gas can be simply added. The key to a modular configuration is to give each medium a clear role, rather than just packing multiple materials into a frame and calling it a day.

1. Distinguish between layered and hybrid configurations

Layered products can each perform different tasks, while direct mixing involves media compatibility and flow distribution. The actual structure should be supported by the corresponding product data and cannot be assembled at will on site.

The idea behind a layered configuration is to let the air flow pass through different media layers in sequence, with each layer handling a specific gas. This structure makes it easy to judge the load and maintenance timing of each layer separately. Direct mixing is to physically mix different media in the same layer, and the airflow contacts multiple media at the same time. The two methods have different airflow distribution, resistance and replacement methods. Aili Industry ischemical filter selection, the media is configured according to the target gas.In box chemical filters andV-shaped chemical filters correspond to different structural forms. The relationship between levels and filtering requirements can be found inISO cleanliness level comparison。

2. Verify target gas item by item

Acid gas, organic matter and other components may cause loads at the same time, and the performance and total resistance under combined working conditions should be checked. A drop in one gas does not mean that other objects meet the requirements.

The removal efficiencies of different components in the mixed gas may affect each other. Acidic gases and organic vapors have different adsorption mechanisms, and the actual performance after combination needs to be confirmed separately for each target gas. Aili Industry isFFU chemical filter package, the media configuration can be checked according to the target composition of the circulating air.In the Plate chemical filters are suitable for space-constrained filtration sections. The relationship between combination configuration and resistance changes can be referred toHEPA FAQs and Selection Guide。

3. Examples of project judgment

When the fresh air contains acid gas and organic matter, different medium layering schemes can be compared and the export targets of the relevant gases can be agreed upon respectively.

When the fresh air contains both acidic and organic components, the layered configuration allows each layer to undertake corresponding tasks, and the two types of gases are detected separately during acceptance. If only one type is tested, there will be no basis for whether the other type meets the standard.

5. Verification and subsequent use

The filter media ultimately needs to be loaded into the actual structural work. When checking gas suitability, the effective area, air flow distribution, material condition and sealing should also be confirmed. When there are differences between sample data and field conditions, the differences should be explained and corresponding verification arranged to avoid comparing only a single number.

Aili Industry isIn the chemical filter combination plan, the configuration basis is explained according to the target gas of each layer of media.The box-type chemical filter can check the fan residual pressure according to the number of layers and total resistance.

6. Related questions and answers

Is it better to mix different filter materials together?
uncertain. The efficiency and capacity of a mixing configuration cannot simply be added and need to be checked separately for each target gas.

Which is better, layering or blending?
Depends on gas composition, space and maintenance methods. Layering makes it easier to judge the load separately, and the hybrid structure is more compact, but both methods require corresponding product information support.

Will the total resistance increase after combining?
Usually yes. The increase in the number of layers or media will affect the total resistance, and the fan margin and actual air volume need to be checked.

9. Aili Industrial products and equipment supporting equipment

Aili Industry provides chemical filters and clean air supply equipment selection packages. It can compare FFU package, box type, flat type and V-shaped products according to gas composition, treatment air volume and installation conditions. The manufacturing and supporting system covers the independent research and development and production of motors and fans, control systems, sheet metal, air filters and complete machine assembly, making it easy to jointly confirm the filter section, power and structural conditions. The specific gas effect, environmental suitability and service life still need to be verified based on the corresponding configuration data and actual working conditions.
