The chemical filter, fan and control system are supplied by the same manufacturer. The core value is that the resistance, air volume and control logic can be put on the same table for verification during the design stage. Aili Industrial's manufacturing and supporting system covers the independent R&D and production of motors and fans, control systems, sheet metal, air filters and complete machine assembly. Such projects do not require the transmission of parameters back and forth between filter manufacturers, fan manufacturers and control suppliers. With fewer interfaces, there are fewer links that can cause problems.

The three most common breakpoints for cross-manufacturer matching

In chemical filtration projects, when filter sections, fans and controls belong to different links, interface problems are usually exposed during the commissioning stage. The first category is that the resistance does not match : the filter section manufacturer provides resistance according to the rated air volume, and the fan manufacturer selects the model according to the nameplate curve. The actual operating point does not match the two, and the only way to make it up is to adjust the speed or add a baffle. The second category is mismatched air volume distribution : when multiple modules or multiple FFUs are connected in parallel, the resistance differences of each branch are not checked during the selection stage, resulting in biased flow after operation. The third category is that the control signals do not match : the filter section pressure difference and air volume status are not included in the control logic, and operators can only rely on regular inspections to detect abnormalities. Aili Industrial makes filter sections, fans and controls at the same time. These three types of breakpoints can be processed in advance in the same set of packages.

The resistance data and fan curve are determined according to the same working conditions.

The resistance of the chemical filter section changes with the air volume, and the static pressure and power of the fan also change with the air volume. The two must be compared at the same operating point. When Aili Industrial is supporting the equipment, it first determines the filter section structure according to the target gas and air volume, obtains the resistance characteristics under the corresponding air volume, then selects the fan operating point based on this, and checks the speed adjustment range and margin. If the project subsequently adjusts the air volume or adds filter sections, the resistance changes can be rechecked within the same system without the need to re-coordinate with external suppliers. For the check method of filter section resistance and fan residual pressure, please refer toHow to check the residual pressure outside the machine after MAU adds a chemical filtration section?。

Corresponding design of control logic and filter section structure

The control system is not just about starting, stopping and speed regulation, it needs to reflect the actual operating status of the filter section. An increase in the filter section pressure difference indicates dust accumulation or moisture, and deviation of the air volume from the setting indicates a change in system resistance. If these signals are not included in the control logic, operation management can only rely on people running to the site. Aili Industrial's control system and filter section structure are designed in the same supporting system. The monitoring points for pressure difference, air volume and operating status can be determined at the selection stage instead of adding sensors later. For scenarios where multiple FFUs are connected in parallel, the group control system can coordinate speed adjustment based on the equipment status and filter section characteristics. Regarding the relationship between fan speed regulation and filtration matching, please refer toCan chemical filters be paired with EC fans to improve operational regulation?。

Sheet metal and complete machine assembly allow interfaces to be adjusted on site

The connecting ducts, frames, access doors and sealing structures between the filter section and the fan are often non-standard parts, and are also the easiest places to push the envelope between multiple suppliers. Aili Industrial's sheet metal and complete machine assembly capabilities cover this part. The box size, interface position and maintenance method can be adjusted according to the on-site space. There is no need for the filter element manufacturer and the fan manufacturer to make half and then splice them on site. In retrofit projects, it is common for the original system frame dimensions to be non-standard, and this ability to adjust to site conditions is more practical than a standard product catalog.

The boundaries of integrated supporting facilities must be clearly defined

Providing filter sections, fans and controls at the same time can reduce interface omissions, but it cannot replace target gas performance and on-site verification. The gas effect depends on the medium configuration and actual working conditions. The fan and control solve air transportation and operation management, and the two cannot prove each other. During project acceptance, gas detection, air volume balance and sealing inspection still need to be carried out separately. An all-in-one package makes these verifications easier to coordinate, rather than making them unnecessary.

Aili industrial supporting equipment

For projects that combine chemical filtration, fans and control, Aili Industries usually follows three steps: first determine the filter section resistance according to the target air volume and gas requirements, then select the fan operating point, and finally connect the pressure difference and air volume signals to the control logic. The three steps are completed within the same supporting system. In terms of product form, box-type MAU matching can be referred toMAU box type chemical filter , product series can be viewedChemical filter product range . Device-side applications can useChemical filter FFU type, integrated chemical adsorption layer withHEPA/ULPA filter particle filtration, FFU group control system can be configured according to the speed regulation and status management of multiple devices. The motors and fans are independently developed and produced. The control system, sheet metal and the entire machine are assembled in the same system. Changes in filter section resistance, fan operating points and control interfaces do not need to be transferred across manufacturers. The specific gas effect, energy consumption data 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

Are all components of the entire industry chain made by ourselves?
Aili Industry covers motors, fans, control systems, sheet metal, air filters and complete machine assembly. The core links are produced independently. The supporting scope can be combined according to project needs. The specific scope is subject to product information.

Is the integrated package cheaper than purchasing separately?
The price depends on the configuration range. The value of integration is more reflected in the interface connection and debugging efficiency, rather than the unit price. The reduced coordination costs in a renovation project are often more substantial than the unit price difference.

Is it okay to just buy the filter element and use the existing fan and control?
Yes, but you need to recheck the filter section resistance, fan curve and control logic to confirm that the existing equipment can match the operating conditions of the new filter section.
