Description
ebm-papst 8314G is a high-reliability compact DC axial cooling fan engineered in a standard 80 x 80 x 32 mm (3.15 x 3.15 x 1.26 in) square form factor. Operating on a nominal 24 VDC supply across a 12 to 28 VDC range, it delivers an aerodynamic airflow of 31.8 CFM (54.0 m³/h) at 3,300 RPM while drawing only 2.5 W of power at a quiet 36 dB(A) acoustic profile. The unit is constructed with a rugged glass-fiber reinforced PBT plastic housing, a glass-fiber reinforced PA plastic impeller, and maintenance-free Sintec sleeve bearings configured for exhaust over struts. Factory integrated reverse polarity and locked-rotor overload protection ensure continuous, safe operation, complemented by stripped AWG 22 lead wires and global UL, CSA, VDE, and CE compliance.
Key Features
- Optimized Aerodynamics: Produces 31.8 CFM (54 m³/h) airflow at 3,300 RPM for efficient thermal dissipation in dense electronics.
- Durable Sintec Bearings: Engineered sleeve bearing system provides up to 70,000 hours of continuous service life at 40 °C.
- Robust Composite Housing: Features glass-fiber reinforced PBT frame and PA impeller for structural integrity and high flame retardancy.
- Integrated Circuit Protection: Built-in reverse polarity and locked-rotor protection safeguards fan circuitry against electrical and mechanical fault conditions.
- Standard Compact Footprint: Standardized 80 x 80 x 32 mm profile facilitates straightforward drop-in integration across modern industrial systems.
