Can the chemical filtration section of the air conditioning box take into account both acid gas and organic gas?

The chemical filtration section of the air conditioning box can be evaluated to handle acid gases and organic gases simultaneously, but the media must be configured for specific components and the mixing load must be checked. The multi-gas designation alone does not guarantee that all acid gases and organics are valid. The adsorption mechanisms of acid gases and organic gases are different, and the combination configuration needs to be confirmed separately, rather than just selecting a product with the 'multi-gas' label.

1. First determine whether it has passed through the same filter section

External input and internal station release may take different air paths. The air conditioning box filtration cannot automatically cover local contamination that has not entered the treatment section.

The acid gas brought in by the fresh air will pass through the filter section of the air-conditioning box, but the organic gas released from the workstations inside the workshop may enter the room through return air or local circulation, and may not necessarily pass through the same filter section. If the two airflow paths are different and only chemical filtration is configured in the air-conditioning box, the internal release part will not be processed. Aili Industry isa chemical filter, confirm the configuration according to the gas source and processing location.When selecting Box-type chemical filter is suitable for MAU fresh air section,FFU chemical filter can be used with FFU to treat circulating air. The relationship between levels and filtering requirements can be found inISO cleanliness level comparison。

2. Compare combinations and system conditions

Check the relevant gas properties, medium sequence, temperature, humidity and capacity respectively, and calculate the total resistance and replacement space. Increasing the number of combined layers may change the original air supply capacity.

The media of acid gas and organic gas are usually different, and the order of layered configuration will affect the load of each layer. Temperature and humidity also affect adsorption and reaction efficiency. Aili Industry isType V chemical filter andIn the flat chemical filter package, the structural form is compared according to the installation space and air volume. The total resistance after combination needs to bethe FFU fan filter unit or air conditioning box fan. Check the residual pressure of For the relationship between combination configuration and resistance, please refer toHEPA FAQs and Selection Guide。

3. Examples of project judgment

When external acid gas enters with fresh air and solvent comes from indoors, the division of labor between fresh air treatment, local exhaust, and circulating filtration can be compared.

The reasonable approach for such projects is to handle them separately: the fresh air section is configured with chemical filtration for acid gases, and indoor solvent release is handled through local exhaust or circulation filtration. Verify the two parts separately instead of placing all expectations on one filter section of the air-conditioning box.

5. Verification and subsequent use

After the filter section is added or adjusted, the actual air supply and target gas should be checked separately. Recording fan settings, air volume, and temperature and humidity can help explain subsequent changes. Gas effects, particle requirements and room airflow each have corresponding methods, and passing one of them cannot replace the acceptance of all.

Aili Industry isIn the chemical filter combination plan, the media configuration basis is explained separately for acid gas and organic gas.The box-type chemical filter can check the fan residual pressure according to the number of layers and total resistance. The specific effect is subject to on-site gas detection.

6. Related questions and answers

Can one filter section handle acid gas and organic gas at the same time?
It can be evaluated, but the media needs to be configured for specific ingredients and the mixing load must be checked. It cannot be judged based on the product name alone.

Is it okay to use the same medium for acid gas and organic gas?
Usually not. The adsorption or reaction mechanisms of the two types of gases are different, and the corresponding media need to be checked separately.

What should I do if the air volume drops after combination?
It is necessary to check the total resistance and fan margin, and adjust the number of layers, filter area or fan configuration if necessary.

9. Aili Industrial products and equipment supporting equipment

Aili Industry provides chemical filters and clean air supply equipment selection and matching, and can check the air-conditioning box matching based on fresh air gas, filter section location, fan residual pressure and maintenance channels. 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.
