Description
The Sunon PF60251B3-1000U-A99 (also known as PF60251B31000UA99) is an industrial-grade brushless DC axial fan engineered in a standard 60 x 60 x 25 mm (2.36 x 2.36 x 0.98 in) square frame profile. Operating across a nominal 12 VDC supply, it delivers a high-velocity airflow of 29.0 CFM (49.27 m³/h) and static pressure of 0.41 in H₂O (102.1 Pa) at a rated rotational speed of 6200 RPM. Mechanical construction features UL 94V-0 flame-retardant thermoplastic PBT for both the housing and impeller, supported by a precision ball bearing system rated for 70,000 hours of continuous operation at 40°C. Standard electrical safeguards include automatic restart recovery from locked-rotor conditions and integrated reverse polarity protection for mission-critical electronic cooling.
Key Features
- Precision Ball Bearing System: Delivers robust rotational stability and ensures an extended L10 operating life of 70,000 hours at 40°C.
- Aerodynamic High-Pressure Profile: Generates up to 29.0 CFM airflow and 0.41 in H₂O static pressure for dense thermal enclosures.
- Integrated Circuit Protections: Features automated locked-rotor shutdown with ten-second automatic restart recovery alongside reverse polarity protection.
- Flame-Retardant Thermoplastic Build: Incorporates UL 94V-0 rated PBT frame and impeller construction to withstand harsh industrial environments.
- Low Acoustic Signature: Operates at an average 37.5 dB(A) sound level optimized for high-efficiency forced-air cooling.
