delta AUB0924HH DC24V 0.25A axial fan

Description

The Delta Electronics AUB0924HH is a high-performance 92mm DC axial fan engineered for critical thermal management in industrial automation and telecommunications infrastructure. This unit features Delta’s proprietary Superflo Bearing system, which integrates a permanently lubricated mechanism to ensure operational stability comparable to ball bearings while maintaining the acoustic profile of sleeve bearings. Designed for Original Engineering specifications, this 24V DC model delivers a balanced airflow-to-noise ratio suitable for continuous duty cycles. The 2-wire configuration ensures simplified integration into standard power circuits without PWM or tachometer requirements, prioritizing reliability in constant-speed applications.

INDUSTRIAL APPLICATION
This specific model is optimized for forced convection cooling within enclosed Variable Frequency Drives (VFDs) and rack-mounted power supply units where 24V bus voltage is standard. The Superflo bearing design mitigates oil leakage and friction wear, making it a superior replacement for standard sleeve bearing fans in vertically mounted server chassis or CNC control cabinets. Its high static pressure capability ensures effective heat dissipation through dense heatsink fins or dust filters. We verify Technical Compatibility for legacy system maintenance and offer competitive Lead Time for bulk procurement.
