Description
The Delta AFB0612HHE-T500 (also known as AFB0612HHET500) is a compact, high-pressure 60x60x38 mm (2.36×2.36×1.50 in) DC brushless tubeaxial cooling fan engineered with a 2-phase, 4-pole motor architecture. Operating at a nominal 12 VDC, this cooling unit generates a high-velocity 46.17 CFM (78.44 m³/h) airflow and an impressive 0.793 in H₂O (197.5 Pa) static pressure at 8000 RPM to overcome dense thermal impediments. Structural reliability is ensured by a robust dual-ball bearing assembly, UL 94V-0 flame-retardant plastic housing, and internal motor windings insulated by a specialized 0.005 mm parylene protective coating. Comprehensive electrical safety includes internal reverse polarity protection, locked-rotor current shutdown, and pre-stripped 330 mm UL 1007 AWG #24 lead wires for dependable system integration.
Key Features
- IP55 Environmental Protection: Motor winding and PWB assemblies feature a protective 0.005 mm parylene coating against dust ingress and water spray.
- High Static Pressure: Delivers 0.793 in H₂O (197.5 Pa) back-pressure capability engineered specifically for densely packaged thermal heatsinks.
- Precision Dual Ball Bearings: Heavy-duty dual ball bearing system guarantees an extended continuous operational lifespan of 70,000 hours at 40°C.
- Locked-Rotor Safety Circuit: Auto-shutdown impedance design prevents motor burn-out and circuit overheating during 96 hours of locked-rotor conditions.
- Flame-Retardant Construction: Housing frame and aerodynamic impeller are molded from UL 94V-0 reinforced thermoplastic for harsh industrial duty.

Applications
The Delta AFB0612HHE-T500 axial fan is primarily integrated into compact 1U and 2U rackmount server chassis, network security appliances, and carrier-grade optical transport multiplexers where deep thermal heatsinks require concentrated impingement airflow. Its parylene-coated IP55 construction makes it exceptionally suited for outdoor telecommunications base stations, ruggedized edge-computing gateways, and modular industrial power supplies exposed to condensation and ambient particulate. In factory automation and medical laboratory environments, maintenance teams deploy this component across closed-loop analyzer instrumentation, embedded machine controllers, and robotic motor drive modules.
