Description
Delta AFB0912HH-R00 (also known as AFB0912HHR00) is a heavy-duty 92 x 92 x 25.4 mm (3.62 x 3.62 x 1.00 in) DC brushless tubeaxial cooling fan engineered for continuous thermal management in high-density electronics enclosures. Powered by a two-phase, four-pole DC motor, this fan delivers an optimal balance of airflow and static pressure, producing 57.92 CFM (98.4 m³/h) and 0.221 in H₂O (55.1 Pa) at 3200 RPM while consuming a nominal 3.00 W. Built with high-grade dual ball bearings and UL 94V-0 flame-retardant thermoplastic housing and impeller, it offers exceptional rotational reliability and a service life rating of 70,000 hours at 40 °C. The unit includes reverse polarity protection, locked rotor impedance shutdown with auto-restart, and a dedicated third-wire Rotation Detect (RD) open-collector locked rotor alarm signal.
Key Features
- Dual Ball Bearings: Heavy-duty dual ball bearing system delivers 70,000 continuous operating hours under harsh industrial environments.
- Rotation Detect Output: Integrated blue open-collector RD alarm wire provides instant locked-rotor fault monitoring for host logic controllers.
- Aerodynamic Efficiency: Generates 57.92 CFM airflow and 0.221 in H₂O static pressure for forced-air electronics ventilation.
- UL 94V-0 Construction: Flame-retardant thermoplastic frame and impeller ensure superior fire safety and rugged mechanical durability in field deployments.
- Comprehensive Motor Protection: Integrated impedance protection prevents thermal failure during 96-hour rotor stalls, reinforced with reverse polarity safeguards.
