Description
The Delta BFB1012L-AF00 (also known as BFB1012LAF00) is a high-reliability 12 VDC centrifugal blower fan engineered with a compact 97.8 x 95.5 x 33.0 mm (3.85 x 3.76 x 1.30 in) scroll housing for targeted high-pressure thermal dissipation. Powered by an internal two-phase, four-pole brushless DC motor, the unit delivers a nominal speed of 2,700 RPM, producing 23.17 CFM (39.36 m³/h) of airflow against static pressures up to 0.585 in H₂O (145.6 Pa) while drawing an efficient 4.4 W. Its heavy-duty construction pairs flame-retardant UL 94V-0 plastic housing and impeller assemblies with precision dual ball bearings rated for 50,000 hours of continuous L10 operation. Electrical integration is managed via 325 mm UL 1007 AWG #24 lead wires providing integrated locked rotor impedance protection, polarity safeguard, and a dedicated open-collector frequency generator (FG) tachometer speed sensor.
Key Features
- High-Static Scroll Design: Engineered scroll housing generates 0.585 in H₂O back pressure for overcoming high-impedance thermal loads.
- Dual Ball Bearing System: Premium precision dual ball bearings provide an exceptional 50,000-hour L10 continuous operating life.
- Open-Collector Tachometer Output: Dedicated third blue frequency generator lead provides accurate closed-loop rotational speed monitoring.
- Robust Circuit Protection: Built-in 96-hour winding locked-rotor impedance protection and reverse polarity safeguard prevent drive burnout.
- Flame-Retardant Construction: Molded with high-grade UL 94V-0 thermoplastic housing and impeller for demanding industrial compliance.

Applications
The Delta BFB1012L-AF00 centrifugal blower fan is purposefully built for ducted cooling assemblies and narrow thermal passages requiring concentrated air displacement against high system flow resistance. It serves as a vital cooling component across 1U/2U telecom power shelves, medical diagnostics instrumentation, server rack card cages, and commercial 3D printer extruders. Industrial automation OEMs also integrate this blower for localized heat sinking in programmable logic controller (PLC) enclosures, motor drive control modules, and projection equipment.
