Description
ebm-papst 8312L is an industrial-grade brushless DC tubeaxial compact fan engineered within a standard 80 x 80 x 32 mm (3.15 x 3.15 x 1.26 in) square profile. Powered by a dependable 12 VDC supply across a flexible 6 to 15 VDC operating window, it delivers an optimized airflow of 18.8 CFM (32.0 m³/h) at a rated speed of 2000 RPM while consuming a low 1.2 W of power. The unit features a rugged glass-fiber reinforced PBT plastic housing paired with a glass-fiber reinforced PA plastic impeller, rotating clockwise on a dual ball bearing system that yields an acoustic noise signature of just 24.0 dB(A). Electrical termination is achieved via factory-stripped and tin-plated AWG 22 lead wires, backed by integrated electronic protection against reverse polarity and blocked-rotor conditions.
Key Features
- Aerodynamic Efficiency: Delivers 18.8 CFM of forced convective cooling with low 24 dB(A) acoustic noise.
- Robust Construction: Fiberglass-reinforced PBT housing and PA impeller withstand harsh continuous operating environments reliably.
- Precision Ball Bearings: Heavy-duty dual ball bearing system guarantees an extended 80,000-hour service lifespan at 40°C.
- Electronic Motor Protection: Integrated circuitry guards against reverse polarity connection and rotor overload or lockup.
- Standard Compact Footprint: Standardized 80x80x32mm enclosure allows drop-in mechanical integration across legacy industrial thermal assemblies.
