Description
The Delta AFB0805H-F00 (also known as AFB0805HF00) is an industrial-grade 5 VDC brushless tubeaxial cooling fan measuring 80.0 × 80.0 × 25.4 mm (3.15 × 3.15 × 1.00 in). Driven by an electronically commutated two-phase, four-pole motor, it delivers 35.31 CFM (60.0 m³/h) of airflow and 0.159 in H₂O (39.6 Pa) static pressure at a rated speed of 3000 RPM while consuming just 2.15 W. Construction features flame-retardant UL 94V-0 plastic housing and impeller assemblies suspended on a precision dual ball bearing system for extended reliability. Electrical interfacing is handled via three UL 1007 AWG #24 lead wires providing positive, ground, and an open-collector frequency generator (tachometer) speed monitoring signal.
Key Features
- Precision Dual Ball Bearings: Engineered bearing system delivering an operational service life of 70,000 hours continuous duty at 40°C.
- Integrated Frequency Generator: Open-collector tachometer signal on the blue lead wire enables real-time motor speed monitoring.
- Flame-Retardant Construction: Molded with high-strength UL 94V-0 compliant thermoplastic frame and impeller materials for industrial safety.
- Locked Rotor Protection: Motor winding impedance and automated shutdown circuitry protect the fan against locked-rotor thermal damage.
- Efficient Aerodynamics: Tubeaxial impeller profile produces 35.31 CFM airflow with quiet acoustical emission of only 31.0 dB(A).

Applications
The Delta AFB0805H-F00 axial fan is primarily engineered for low-voltage spot cooling in compact embedded computers, network routing switches, and edge computing appliances. It provides forced-air thermal dissipation within laboratory analytical instruments, industrial Human-Machine Interface (HMI) consoles, and point-of-sale terminal enclosures. Furthermore, maintenance engineers deploy this unit for component-level exhaust ventilation in automated test fixtures and peripheral controller assemblies.
