Product Overview – DC Blower 4008
The DC Blower 4008 is a high-efficiency micro centrifugal fan, sized at 40mm x 40mm x 8mm, ideal for advanced applications where space is tight but airflow and cooling performance are critical. It features a high-speed brushless DC motor and a precision-balanced impeller to deliver strong airflow with minimal noise, making it a versatile choice for high-tech and mobile devices.
Whether you're working in consumer electronics, automotive engineering, or drone technology, the DC Blower 4008 offers stable performance, low power consumption, and long operational life, essential for modern compact systems.
Manufacturing Process & Quality Assurance
As globally recognized DC Blower suppliers, we follow a rigorous and standardized manufacturing process to ensure every 4008 blower meets international quality benchmarks:
Design & Prototyping – CAD simulations and aerodynamic testing in wind tunnel laboratories.
Injection Molding – Flame-retardant PBT (UL94V-0) housing and impellers are formed using high-precision molds.
Motor Assembly – Premium brushless DC motors are integrated, tested for EMI control and energy efficiency.
Impeller Balancing – Each impeller is dynamically balanced for vibration-free operation.
Final Assembly & Testing – Includes airflow, noise level, durability, and functional tests under simulated working conditions.
Packaging & Certification – Products are labeled and packed after passing UL, CE, TUV, RoHS 2.0, and are tracked through our ISO 9001/ISO 14001 certified processes.
Applications – Built for Innovation
1. Drones (UAVs)
The DC Blower 4008 plays a crucial role in cooling flight controllers, image processing units, and communication modules in drones. Its compact size and efficient thermal management allow drones to fly longer and operate more reliably, especially in high-temperature environments or enclosed modules.
2. Power Vehicles / High-Energy Systems
In electric bikes, power-assisted scooters, and mobile battery packs, this blower supports thermal regulation of power electronics and battery management systems (BMS). Its durability and low-noise operation ensure smooth performance during extended or rugged usage.
These applications demand lightweight, energy-efficient cooling solutions, and the DC Blower 4008 meets these requirements with excellence.
