Description
The Delta FFB0912VH-F00 (also known as FFB0912VHF00) is an industrial-grade DC brushless tubeaxial cooling fan engineered in a standardized 92 x 92 x 25.4 mm (3.62 x 3.62 x 1.00 in) square form factor. Powered by a four-pole, two-phase brushless motor operating across 7.0 to 13.8 VDC, it delivers up to 81.97 CFM (139.3 m³/h) of airflow and 0.319 in H₂O (79.5 Pa) static pressure at a rated speed of 3700 RPM while consuming just 7.20 W. Built with high-durability dual ball bearings and flame-retardant UL 94V-0 plastic housing and impeller, the assembly provides an extensive L10 service life of 70,000 hours at 40 °C. The unit includes reverse polarity protection, locked-rotor impedance safety, and a dedicated third blue lead wire for open-collector frequency generator (tachometer) speed feedback.
Key Features
- Dual Ball Bearing Design: Precision dual ball bearing assembly ensures 70,000 hours continuous service life under elevated operating temperatures.
- High-Static Aerodynamics: Optimized blade geometry delivers 81.97 CFM and 0.319 in H₂O pressure across dense enclosure heat sinks.
- Open-Collector Tachometer: Dedicated blue wire outputs a frequency generator pulse signal for real-time motor speed monitoring.
- Comprehensive Electrical Safeguards: Integrated locked-rotor impedance protection and reverse polarity protection prevent thermal overload and operational motor damage.
- Flame-Retardant Construction: Housing frame and aerodynamic impeller are molded from UL 94V-0 compliant high-strength engineering plastic.
