The 10025 series and 11025 of Sifang Optoelectronics car seat ventilation fans are independently developed by the company, using DC brushless technology and double ball bearings. Under the same conditions, they can achieve high wind pressure (and similar air volume) at a lower speed. The same appearance can meet both suction and blowing needs, making it convenient for platform applications. The products have performance characteristics such as high air volume, high wind pressure, long service life, and low noise, meeting the needs of car use.
