Aili Industrial non-standard customized ULPA ultra-high efficiency filters are used for clean air supply equipment that require specific dimensions, thickness or installation interfaces.
Product customization starts from the equipment installation conditions and operating requirements, confirms the filtration grade, filter material, filtration area, air volume and resistance, and then implements the frame, sealing and fixed structure. U15, U16 or U17 configurations can be evaluated according to project requirements. Specific performance is subject to the specifications and test results of the corresponding products.

Whether a special structure can be realized needs to be evaluated based on manufacturing conditions, performance requirements and testing conditions.
Confirm the overall size according to the available space, and check the target air volume and allowable resistance to avoid just reducing the size while ignoring the filtration area and air supply needs.
Incorporate the sealing contact surface, support position and fixed structure into the confirmation drawing to make the filter correspond to the equipment installation conditions.
Evaluate replacement configurations based on old product nameplates, drawings, installation photos, and operating parameters. When the original data is incomplete, priority is given to checking the key dimensions that affect installation and performance.
The project can first confirm the sample as needed, check the installation and operating conditions on the actual equipment, and then solidify the drawings, materials and acceptance requirements for the batch product.

When customizing, you should distinguish the outer frame size, effective air outlet size and installation matching size, and indicate the size measurement benchmark.
size category |
Confirm key points |
|---|---|
Frame width and height |
Whether it is suitable for installation openings and positioning structures |
Total product thickness |
Whether seals and protruding structures are included |
Effective air outlet size |
Whether it meets the air supply range of the process area |
Sealing position dimensions |
Whether it corresponds to the equipment contact surface or knife edge |
Fixed position size |
Whether it cooperates with the buckle, pressure plate and limiter |
critical tolerance |
Avoid being too tight, too loose or the seal is misaligned |
Installation photos can help understand the structure, but critical dimensions should still be confirmed through measurements or drawings.
Small-sized filters may have a larger frame ratio, so you should pay attention to the actual effective air outlet area when selecting. Long strip filters need to be combined with the layout of the matching box and fan to check the air distribution and installation stress.

Whether non-standard sizes are suitable for the project needs to be confirmed between the installation conditions and performance requirements.
When customizing a ULPA filter, the filtration level and operating parameters need to be clearly defined at the same time.
Filtration level: Confirm U15, U16 or U17 according to process and acceptance requirements, and agree on the basis for testing.
Operating air volume: clarify the actual air volume that a single filter needs to bear, or provide the target surface wind speed and effective air outlet area.
Allowable resistance: clearly specify the initial resistance limit under the air volume, and check the air supply capacity of the equipment when the resistance increases later.
Design adjustment: When space and performance are difficult to meet at the same time, adjustments to filter material, thickness, filter area or equipment supporting conditions can be evaluated.
Aili Industrial can combine filter manufacturing and fan matching capabilities to help confirm implementable product configurations.
Confirm the surface where the gasket is located, the contact width and the pressing conditions, and correspond to the equipment frame and fixings.
Confirm the location, cross-section and matching dimensions of the equipment blade, and check the installation direction, positioning and disassembly and assembly space.
The filter is secured by defined frames and support structures. Buckles, pressure plates or other fixings should avoid direct pressure on the filter material and keep the installation position stable.
The sealing methods are different, and the matching interfaces are also different, so they cannot be interchanged based only on the outer frame size.
When the original filter is discontinued, the model is unknown, or the supply specifications change, replacement requirements can be reconfirmed through existing data.

Equipment performance should be re-evaluated when changes in grade or filter media are involved. After the replacement parts are in place, installation and operation verification are completed according to project requirements.
Requirement submission → Technical parameter confirmation → Drawing confirmation → Sample verification → Batch configuration confirmation
01 Submit requirements: Provide equipment usage, installation space, filtration level, air volume and interface information.
02 Confirm parameters: Check size, filter material, resistance, sealing and testing requirements.
03 Confirm drawings: Confirm key dimensions, tolerances, installation directions and accessory configurations.
04 Verification sample: According to the project arrangement, check the installation, sealing and air supply performance on the actual equipment.
05 Solidified batch configuration: Use the confirmed drawings, materials, labels and acceptance conditions for subsequent procurement.
If the configuration needs to be adjusted during sample verification, the drawings and technical requirements should be updated simultaneously.

Aili Industry covers air filter manufacturing, motor manufacturing, independent research and development and production of fans, control system development, sheet metal processing and complete machine assembly. Non-standard filters and supporting equipment can be confirmed together.
For new equipment projects, filters, boxes and installation frames can be coordinated; for modification and replacement projects, existing interfaces and operating conditions can be combined to provide product selection and customization support.
It can be evaluated first, and the filtration level, air volume, resistance and sealing requirements need to be confirmed.
It can be confirmed by combining the actual size and original performance data, and cannot just copy the appearance.
Possibly, it should be rechecked based on the new filter area and filter element configuration.
It can be evaluated, but the air volume, frame structure and fixing method need to be confirmed.
Samples and verification requirements can be confirmed according to project arrangements, and batch configuration can be solidified after verification.
The required level, operating parameters and acceptance conditions should be re-clarified, and then the replacement plan should be confirmed.
Please submit equipment drawings, installation dimensions, filtration level, air volume and resistance requirements. Aili Industry will combine manufacturing and equipment supporting conditions to assist in confirming the configuration of non-standard ULPA filters.
