9HV3612P3K001

9HV type High Static Pressure Fan Features High Static Pressure and High Airflow This fan delivers a maximum static pressure of 1,400 Pa and a maximum airflow of 3 0.72 m /min. Compared with the current model,* the maximum static pressure has increased by 1.67 times and maximum airflow has increased by 1.04 times. Space-saving This fan provides the same cooling performance as our conventional 40 40 mm fans.** The reduced fan size enables enhanced design flexibility. High Energy Efficiency and Low Noise The PWM control function enables the external control of fan speed, contributing to lowering noise and improving energy efficiency of devices. * Current model: San Ace 36 9GX type 36 36 28 mm (9GX3612P3K001). ** Conventional fans: 40 40 28 mm San Ace 40 9GV type (9HV0412P3K001) and 9GAX type (9GAX0412P3S001). 363628 mm Specications The models listed below have ribs and pulse sensors with PWM control function.
