Aili industrial chemical filters can be selected around MAU fresh air treatment, FFU circulating air and related clean air supply projects. The specific applicability needs to be confirmed based on the target gas, air volume, environment and structure. The effect cannot be judged solely by the name of the product series. Product line coverage is the starting point for matching, not the conclusion of model selection.

Supporting location of MAU fresh air treatment project

The location of the chemical filtration section in a MAU project usually depends on the source of fresh air pollution and downstream protection objects. If external acidic and alkaline gases or organic emissions are the main problem, the filter section is usually located at a suitable location after the fresh air inlet and before the surface cooler; if there is still gas load after the indoor return air is mixed, it needs to be configured in the mixing section or air supply section. Aili Industrial's box-type chemical filters can be matched according to the size of the functional section of the air-conditioning box. The flat-plate and V-shaped structures are suitable for different space and resistance conditions. Regarding the residual pressure check after MAU adds a filter section, please refer toHow to check the residual pressure outside the machine after MAU adds a chemical filtration section? . The specific location should also avoid high humidity areas and droplet entrainment areas.

Matching form of FFU loop and device-side project

In FFU-related projects, chemical filtration usually appears in two ways: first, the FFU circulation section integrates a chemical adsorption layer, and second, the local air supply section at the equipment end is equipped with chemical filters. The former focuses on AMC control of room circulating air, while the latter focuses on gas protection of micro-environments such as EFEM, lithography equipment air inlets or wafer storage cabinets. Aili Industrial can provide chemical filtration FFU form, integrating chemical adsorption layer and HEPA/ULPA particle filtration. The structure of chemical first and then particles is suitable for areas with AMC control requirements. The compact structure of the equipment can be adapted non-standardly according to space and air volume. Regarding the data requirements for the air inlet at the equipment end, please refer toWhat field data is needed for chemical filtration of the air inlet of lithography equipment?。

Adaptability for replacement and renovation projects

Replacing imported or other brand filter elements in existing systems is a common requirement in Aili's industrial chemical filter matching. This type of project does not necessarily require changing the cabinet or fan, but it does need to be checked according to the original interface size, sealing position and media requirements. Box type, flat type and V-shaped products have different structural forms. When replacing, the original frame status and air flow direction can be confirmed. If the original system had frame deformation or sealing issues, these will also be evaluated. For verification methods involving brand replacement, please refer toWhen changing chemical filter brands, how to confirm that the replacement model can be used?。

Multi-gas and industry application scenarios

Gas objects in different industries vary greatly. When supporting, they are usually grouped according to the ingredient list, rather than a set of configurations covering all scenarios. Semiconductor AMC projects may focus on acids, alkalis, organics, and siloxanes; clean room fresh air may be dominated by external acid gases and organic emissions; the microenvironment at the equipment end needs to be combined with specific process sensitive objects. Aili Industry can provide box-type, flat-type and V-type chemical filtration product selection packages. The product series can be viewedChemical filter product series , box-type MAU matching, please refer toMAU box chemical filter . The sequence and resistance of multi-gas combinations can be checked during the supporting stage, and non-standard sequences can be adjusted according to project conditions.

Boundaries of supporting capabilities

Product line coverage and manufacturing capabilities can bridge the interface but are not a substitute for target gases and demonstration of field operations. Aili's industrial manufacturing end covers independent R&D and production of motors and fans, control systems, sheet metal, air filters and complete machine assembly. This means that filter section resistance, fan operating points and frame structures can be checked in the same package, reducing information breakpoints in cross-manufacturer docking. However, the specific gas effect, applicable environment and replacement cycle still need to be verified based on the corresponding configuration data and on-site working conditions. The actual results are subject to on-site leak detection and gas detection results.

Related questions and answers

Can MAU and FFU projects share the same chemical filter element?
uncertain. The air volume, installation space and air flow direction of the two are different, and the filter element size, surface speed and structural form need to be checked separately. The media types may be similar, but the product formats are usually different.

Can Aili Industrial only provide filter elements without matching fans?
Can. The filter element, box and complete machine package can be selected according to the project scope. When replacing an existing system, you usually only need to check the filter element according to the interface and media requirements.

How to determine whether a project is suitable for box type or V type?
Related to air volume, available space, resistance margin and maintenance access. The resistance, capacity and replacement methods of the two structures should be compared under the same gas target and air volume.
