R80W12BS3B9-07Z104 Nidec 12VDC 2.19A 8056 Server Fan

Description

Nidec R80W12BS3B9-07Z104 80 x 80 x 56 mm 12 VDC 2.19 A dual-motor axial fan is a high-performance cooling unit. This counter-rotating component features a robust PBT plastic housing and PPS impellers, both rated UL 94V-0 for flame retardancy. The internal architecture utilizes a dual ball bearing system to ensure a service life of 70 000 hours at 40 °C. It incorporates a 4-wire interface supporting pulse width modulation (PWM) for precise speed regulation and a tachometer signal for real-time rotation monitoring. The dual-motor design generates high static pressure by utilizing two independent rotors spinning in opposite directions to straighten airflow and minimize turbulence.
