Reach out to our professional sales team via phone, email, or online customer service. Clearly explain your customization needs, such as:

● Performance: Special requirements for wind speed levels, timer duration, energy - saving features, or noise control optimization.

● Application Scenarios: Different environments like warehouses, gyms, or outdoor camping may require specific protection levels and installation methods.

● Appearance: Unique ideas for fan blade shapes, guard styles, or base designs

Based on your requirements, our R & D team will create a detailed product solution within 3 - 5 working days. This includes design drawings, performance parameters, estimated production cycles, and customization costs for your customized fan. We'll communicate the solution to you via email or face - to - face meetings (if needed) to ensure you fully understand every detail. You can provide feedback for modifications, and we'll adjust the solution promptly until you are completely satisfied.

Once the solution is confirmed, we'll sign a customization contract that clearly defines the rights and obligations of both parties, product specifications, delivery time, and payment methods. As per the contract, you need to pay a deposit of 30% - 50% of the total customization cost to confirm the order and start the production scheduling. Upon receiving the deposit, we'll immediately arrange the production schedule for you.

To ensure the quality of mass production, a prototype will be produced before the official production scheduling. After the prototype is completed, strict aging testing will be carried out:

Simulate actual working conditions to test the fan's continuous operation stability and performance indicators (wind speed, energy consumption, etc.).

Only after passing the tests will mass production begin. If there are issues, immediate optimization and adjustment will be made until it meets the standards.

During mass production, we strictly adhere to the quality management system and control every production link. We'll update you on the production progress weekly. You can also contact our project manager at any time to stay informed about the real - time status of your customization. In case of any issues that may affect the delivery time during production, we'll communicate with you immediately to work out a solution together.

After production, our quality inspection team will conduct a comprehensive inspection and commissioning of the fans according to the quality standards and customization requirements specified in the contract. This includes appearance checks (ensuring colors and styles meet customization requirements), performance testing (wind speed, noise, energy consumption, etc.), and safety inspections. Only when the product passes all inspections and is confirmed to fully meet your customization needs will it move to the next delivery stage.

We'll deliver the customized BLDC 200W industrial fans according to the delivery time and method (shipping or self - pick - up, etc.) specified in the contract. After you receive and inspect the goods and confirm there are no quality issues or discrepancies with the customization requirements, you need to pay the remaining balance as per the contract. If any problems are found during the inspection, we'll arrange professional personnel to handle them immediately until you are satisfied.

Even after the customization process is completed, our service continues. We offer comprehensive after - sales services, including maintenance guidance, free repairs during the warranty period (for non - human - caused damages), and technical consultations. If you encounter any problems during use, simply call our after - sales hotline, and we'll respond within 24 hours to solve the issues
