Product Overview – DC Blower 4008
The DC Blower 4008 is a high-efficiency micro centrifugal fan with dimensions of 40mm x 40mm x 8mm, designed for advanced applications where space is limited but airflow and cooling performance are essential. It features a high-speed brushless DC motor and a precision-balanced impeller, providing strong airflow with minimal noise, making it a versatile option for high-tech and mobile devices.
Whether you are involved in consumer electronics, automotive engineering, or drone technology, the DC Blower 4008 delivers stable performance, low power consumption, and a long operational lifespan, which are crucial for modern compact systems.
As a globally recognized supplier of DC Blowers, we adhere to a strict and standardized manufacturing process to ensure that every 4008 blower meets international quality standards:
Design & Prototyping: Utilizes CAD simulations and aerodynamic testing conducted in wind tunnel laboratories.
Injection Molding: The housing and impellers are crafted from flame-retardant PBT (UL94V-0) using high-precision molds.
Motor Assembly: Premium brushless DC motors are integrated and tested for electromagnetic interference (EMI) control and energy efficiency.
Impeller Balancing: Each impeller undergoes dynamic balancing to ensure vibration-free operation.
Final Assembly & Testing: Includes tests for airflow, noise levels, durability, and functionality under simulated working conditions.
Packaging & Certification: Products are labeled and packaged after passing certifications such as UL, CE, TUV, and RoHS 2.0, and are tracked through our ISO 9001/ISO 14001 certified processes.
Drones (UAVs): The DC Blower 4008 is essential for cooling flight controllers, image processing units, and communication modules in drones. Its compact design and efficient thermal management enable drones to operate longer and more reliably, particularly in high-temperature environments or enclosed spaces.
Power Vehicles / High-Energy Systems: In electric bikes, power-assisted scooters, and mobile battery packs, this blower aids in the thermal regulation of power electronics and battery management systems (BMS). Its durability and quiet operation ensure smooth performance during extended or rugged use.
These applications require lightweight, energy-efficient cooling solutions, and the DC Blower 4008 excels in meeting these demands.
