MEC0252V2-000C-A99 Sunon 24V 120x120x25mm DC Axial Fan

Description

The Sunon MEC0252V2-000C-A99 is a professional-grade 120 mm DC axial fan with a nominal voltage of 24 VDC and dimensions of 120 x 120 x 25 mm, designed for high-reliability thermal management in industrial and telecommunications systems. Operating at a power consumption of 3.50 W with a rated current of 0.146 A, this unit features Sunon’s proprietary VAPO bearing system, which leverages magnetic levitation to minimize mechanical friction and ensure ultra-long service life. With a balanced performance profile of 2700 RPM, it delivers a robust airflow of 93 CFM and a static pressure of 0.22 inH2O, making it highly effective at overcoming system resistance. Constructed with UL 94V-0 flame-retardant plastic and weighing 163 g, the fan includes essential safety features such as auto-restart and polarity protection, providing a powerful and quiet cooling solution for power supplies, server racks, and industrial control cabinets at the end.
