Description
ebm-papst 514F is a precision compact DC tubeaxial cooling fan measuring 50 x 50 x 15 mm (1.97 x 1.97 x 0.59 in), engineered for forced-air spot cooling in space-constrained industrial systems. Operating on a 24 VDC nominal supply across a 21.6 to 26.4 VDC input range, it delivers 11.8 CFM (20 m³/h) of airflow at a rated speed of 5000 RPM while drawing only 0.9 W of power with a 30 dB(A) acoustic profile. The assembly is constructed with a rugged fiberglass-reinforced PBT plastic housing, fiberglass-reinforced PA plastic impeller, and a smooth Sintec sleeve bearing system offering an L10 service life of 50,000 hours at 20 °C. Integrated impedance protection guards against reverse polarity and blocked-rotor conditions, with electrical connection made via stripped and tin-plated AWG 28 lead wires.
Key Features
- Aerodynamic Performance: Delivers 11.8 CFM (20 m³/h) of targeted airflow at 5000 RPM with low 30 dB(A) acoustic emission.
- Durable Reinforced Construction: Features fiberglass-reinforced PBT housing and PA impeller for structural stability in compact thermal enclosures.
- Sintec Bearing System: Provides smooth, quiet operation with an extended service life rating of 50,000 hours at 20 °C.
- Comprehensive Motor Protection: Integrated impedance protection shields the motor circuitry against reversed polarity connections and locked-rotor stall conditions.
- Industrial Compliance: Globally certified under CE, UL, CSA, and VDE standards for safety across OEM equipment architectures.
