YY4015M24B SNOWFAN 24VDC 40x40x15mm 4-Wire Axial Fan

Description

SNOWFAN YY4015M24B is a 24VDC 40x40x15mm Axial Fan optimized for high-density thermal management in space-constrained industrial enclosures. This unit features a brushless DC motor integrated with a dual ball bearing architecture, ensuring extended MTBF and superior structural rigidity under continuous operation. The 4-wire configuration supports precise PWM speed control and tachometer feedback, allowing for dynamic cooling adjustments to minimize thermal impedance. With a rated current of 0.12A and high-RPM capability, it generates the necessary static pressure to overcome internal resistance in compact chassis. The aerodynamic PBT impeller is designed to maximize laminar flow while maintaining low vibration levels for sensitive electronic components.
