30mm x 3.5mm thick 5V powered small DC blower fan for cooling
BF3003 (Centrifugal Fan / Blower Fan)
This is a high-quality, inexpensive, slim DC blower fan suitable for cooling. It is ideal for thin spaces where air pressure is needed.
【Product Features】 - The unit price starts at 300 yen for mass production (2,000 pcs per month). - The following specifications can be adjusted during mass production: - Voltage, air volume, and air pressure adjustments - Connector and harness length adjustments - As it is made in China, additional overseas shipping costs will be required for samples. - It is not designed to be heat-resistant or waterproof. 【Product Overview】 This is a small DC blower fan (DC-driven, centrifugal cooling fan). It features a design that balances quality and price. Produced in a factory with a track record of supplying automotive fan motors, it is recommended for those looking to achieve both quality and low cost in cooling fans. Compared to axial fans, blower fans are better at generating air pressure, making them suitable for environments that require pressure. Not only does it ensure the quality of the fan, but during mass production, it also accommodates connector installation and lead wire customization, helping to reduce overall costs.
