Product Title
SANYO DENKI San Ace 38 Low-Power DC Fan – 9GA0312P3K001 | 38x28mm, 12V, 7.4W, 25,000 RPM, Quiet Operation, PWM & Pulse Sensor
Product Overview
The SANYO DENKI 9GA0312P3K001 is a specialized member of the San Ace 38 series engineered for applications where energy efficiency and acoustic comfort are paramount. Operating at a moderate speed of 25,000 RPM, it consumes only 7.4 Watts while delivering 0.6 m³/min (21.2 CFM) airflow and 800 Pa (3.21 inchH₂O) static pressure — sufficient for general ventilation in enclosed electronics without excessive heat or noise generation.
Designed with a ribbed plastic frame for structural stability and equipped with PWM speed control and a pulse sensor, this fan enables intelligent thermal management and real-time monitoring. Its sound level of 59 dB(A) makes it one of the quietest options in its class, ideal for office environments, medical devices, and consumer-facing equipment.
Certified as an Eco Product by SANYO DENKI and compliant with global safety standards, it supports sustainable design goals without compromising reliability.
