Multiple workstations use different solvents, how to divide chemical filtration?
When using different solvents at multiple workstations, filtration needs should be divided according to specific ingredients, release intensity and air supply and return paths. Just because they are organic gases does not mean they share the same filter material and replacement cycle by default. The classification is based on composition and gas flow path, not the broad category of 'organic gases'.
1. First check the spread between workstations
Local exhaust air, shared return air, and open boundaries determine whether contamination is mixed. Priority should be given to reducing source releases, and then determining the scope of concentrated and local treatment.
Whether the air flows between different workstations are connected determines whether the solvent vapor will mix. If each workstation has independent exhaust, it can be processed separately; if the return air is shared or the space is open, different solvent vapors will mix into the same air flow. Aili Industry ischemical filters, confirm the processing range according to the air flow path of the workstation.When selecting FFU chemical filter can be used with circulating air treatment,Box-type chemical filters are suitable for centralized fresh air treatment. The relationship between levels and filtering requirements can be found inISO cleanliness level comparison。
2. Compare mixed load applicability
Different solvents may have different capacity behaviors. It is necessary to describe the key components and their common loads, and verify the key protection areas separately.
The adsorption competition of different solvents on the same medium may affect their respective performance. Alcohols, esters, and aromatic hydrocarbons have different adsorption characteristics, and the capacity and penetration sequence after mixing need to be confirmed separately. Aili Industry isType V chemical filter andIn the flat chemical filter package, confirm the media configuration according to the mixed components. The relationship between the combination configuration and the resistance change can be referred toHEPA FAQs and Selection Guide。
3. Examples of project judgment
If one station is cleaned with alcohol and the other one uses adhesive, the release and return air can be investigated separately before deciding whether to share the filter section.
If the return air from the two workstations is not mixed, filtration can be configured separately; if the return air is shared, the media and replacement cycle need to be confirmed according to the mixed components.

5. Verification and subsequent use
Sampling and investigation need to correspond to actual usage conditions. Keeping records of the occurrence period, source events, ventilation and environment can help determine whether the data is representative. Unknown components should be listed as items to be confirmed and completed through appropriate testing, and limited information should not be expanded into all air conclusions.
Aili Industry isIn the chemical filter multi-station solution, the filtration configuration is confirmed according to the airflow zone and solvent composition. The specific effect is subject to on-site inspection of each station.
6. Related questions and answers
Can different solvents share the same filter material?
uncertain. It needs to look at the specific ingredients and the adsorption competition after mixing, and cannot just judge by the 'organic gas' category.
How to deal with airflow mixing between workstations?
First confirm the degree of mixing, and then configure the filter according to the mixed components; if possible, give priority to reducing mixing through local exhaust.
Does filtering need to be configured individually for each workstation?
Dependent on airflow zoning and maintenance requirements. Workstations with shared return air may be suitable for centralized processing, while workstations with independent exhaust air can be configured separately.

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.
