18mm x 4mm thick 5V powered small DC blower fan for cooling
This is a high-quality, inexpensive, slim DC blower fan for cooling. It is ideal for thin spaces where air pressure is needed.
【Product Features】 - The unit price is from 300 yen during mass production (2,000 pcs per month). - The following specifications can be modified during mass production: - Adjustment of voltage, airflow, and air pressure - Adjustment of connector and harness length - As it is made in China, additional overseas shipping costs will be required for samples. - It is not designed to be heat-resistant or water-resistant. 【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, this product 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 and are effective in environments that require pressure. Not only does it ensure the quality of the fan, but during mass production, it also accommodates connector installation and customization of lead wires, helping to reduce overall costs.
