Description
The ebm-papst 414JHH is a high-performance 40x40x25 mm (1.57×1.57×0.98 in) compact DC axial cooling fan engineered for dense electronic enclosures requiring intense localized heat extraction. Operating on a nominal 24 VDC supply across an 18 to 27 VDC operating window, this compact unit delivers an impressive airflow rate of 14.1 CFM (24.0 m³/h) at a nominal rotational speed of 13,000 RPM while consuming only 3.6 W. Mechanical construction features a rugged glass-fiber reinforced PBT plastic housing paired with a reinforced PA plastic impeller, sustained by long-life dual ball bearings and an exhaust-over-struts airflow direction. The motor incorporates built-in reverse polarity and locked-rotor protection, terminating through stripped and tin-plated AWG 26 lead wires for direct industrial integration.
Key Features
- High-Pressure Aerodynamics: Delivers an impressive 14.1 CFM airflow at 13000 RPM to overcome dense component impedance.
- Dual Precision Ball Bearings: Provides long-term mechanical reliability rated for 57500 hours L10 operating life at 40 °C.
- Reinforced Thermoplastic Build: Features glass-fiber reinforced PBT housing and PA impeller engineered for elevated dimensional stability.
- Integrated Circuit Protection: Features electronic safeguards against electrical reverse polarity and rotor blockage under continuous operation.
- Compact 40mm Form Factor: Engineered with standard 40x40x25 mm dimensions ideal for 1U server chassis and industrial enclosures.
