EISKUHL, specializes in the R&D, production, and sales of high-quality cooling fans. With over 12 years of experience and advanced testing equipment, the company has become a trusted partner for customers across Europe and Southeast Asia.
In January 2024, EISKUHL began mass production of the DC 3510 small blower fan for a Korean customer’s hair removal device project. This case highlights how our engineering expertise and production strength met stringent customer requirements and ensured long-term supply stability.
The customer’s design required a cooling solution with strict electrical and mechanical performance conditions:
Stable speed and air volume under continuous operation.
Current not exceeding 0.25A to maintain energy efficiency and device safety.
Upside-down installation with fan blades facing the heat sink, creating higher structural demands.
Overall thickness not exceeding 10.5mm, which limited design tolerance.
High requirements for plastic deformation control to ensure long-term durability.
These specifications presented challenges in terms of precision engineering, material selection, and production consistency.
EISKUHL’s R&D team worked closely with the customer to refine the DC 3510 small blower fan design. Through careful optimization of the fan’s blade structure, motor configuration, and housing materials, we ensured:
Stable speed and airflow output while staying below the 0.25A current limit.
Mechanical durability suitable for upside-down installation.
Strict adherence to the ≤10.5mm thickness requirement during mass production.
Enhanced quality control to minimize plastic deformation under thermal stress.
All solutions were verified through our in-house testing systems, including CFM airflow measurement, noise tests, temperature cycling, and long-term endurance trials.
Stable Mass Production: Ongoing for 20 months since January 2024.
On-Time Delivery: Monthly shipments fulfilled without delays.
Consistent Quality: Excellent uniformity across batches, meeting all technical requirements.
Customer Satisfaction: Positive feedback for both product performance and EISKUHL’s reliable supply chain support.
This project demonstrates EISKUHL’s ability to meet complex customer requirements with precision-engineered fan solutions. By leveraging advanced R&D, strict quality control, and efficient production capabilities, EISKUHL continues to deliver cooling fans that ensure both performance and reliability for global partners.
