Description
The Sunon GF80251B1-000U-AE9 (also known as GF80251B1000UAE9) is a heavy-duty, IP68-sealed 12VDC brushless axial cooling fan measuring 80 x 80 x 25 mm (3.15 x 3.15 x 0.98 in). Driven by a high-efficiency single-phase 4-pole motor and supported by precision dual ball bearings, it delivers an air delivery rate of 60.0 CFM (102.0 m³/h) with 0.41 in H₂O (102.1 Pa) static pressure at a rated speed of 4800 RPM. Constructed with flame-retardant UL 94V-0 thermoplastic PBT housing and impellers, the fan provides superior resistance against moisture, dust ingress, and harsh chemical exposure. Integrated electronics incorporate full reverse polarity protection alongside locked-rotor auto-restart functionality, ensuring reliable thermal dissipation in demanding industrial electronics.
Key Features
- IP68 Environmental Ingress Rating: Fully encapsulated motor and circuitry provide total dust resistance and continuous submersion waterproofing.
- Precision Dual Ball Bearings: Heavy-duty dual ball bearing system extends operational service life up to 70,000 hours.
- High-Static Aerodynamic Blade: Optimized PBT impeller geometry generates 0.41 in H₂O static pressure against dense system impedance.
- Locked-Rotor Protection: Intelligent shutdown circuitry prevents coil burnout with automatic restarting within ten seconds after unjamming.
- Flame-Retardant PBT Construction: Rigid frame and blades comply with UL 94V-0 flammability standards for elevated thermal environments.
