PF92251V1-1000C-S99 Sunon 12V 92x92x25mm DC Axial Fan

Description

The Sunon PF92251V1-1000C-S99 is a precision-engineered 92 mm DC axial fan designed for high-efficiency thermal management in compact industrial and networking enclosures. Operating on a 12 VDC supply with a power consumption of 4.68 W, this model utilizes Sunon’s advanced VAPO bearing system to ensure long-term stability and minimal mechanical noise. The S99 configuration features a professional 4-wire interface, integrating PWM speed control and Tacho (FG) output for intelligent, system-monitored cooling performance. With a 75 CFM airflow capacity and 0.35 inH₂O static pressure capability at 4500 RPM, it is optimized to provide effective air delivery in space-constrained, high-resistance environments such as server chassis and industrial power supplies. The housing and impeller are constructed from high-quality, UL 94V-0 grade flame-retardant plastic, and the unit supports S1 continuous operation across an ambient temperature range of -10 °C to +70 °C.
