Description
ebm-papst 4414ML is an industrial-grade DC tubeaxial cooling fan engineered for forced-convection heat dissipation within standard 119 x 119 x 38 mm (4.69 x 4.69 x 1.50 in) footprints. Operating on a nominal 24 VDC supply across a flexible 12 to 28 VDC input window, the unit delivers a nominal speed of 3000 RPM with an airflow throughput of 99.0 CFM (168 m³/h) while drawing an efficient 3.2 W. The fan assembly combines a rugged fiberglass-reinforced PBT housing, a fiberglass-reinforced PA plastic impeller, precision dual ball bearings, and an exhaust-over-struts airflow path wired via robust AWG 24 leads.
Key Features
- Aerodynamic Output: Delivers 99.0 CFM (168 m³/h) air performance at 3000 RPM nominal speed for demanding industrial equipment.
- Robust Reinforced Construction: Features a fiberglass-reinforced PBT housing paired with a fiberglass-reinforced PA impeller for long-term mechanical stability.
- Precision Ball Bearings: Engineered with dual ball bearings providing an L10 service life of 67,500 hours at 40 °C.
- Wide Thermal Tolerance: Operates reliably across ambient temperatures from -20 °C to +80 °C under continuous industrial duty cycles.
- Flexible DC Operation: Supports broad supply voltage variations spanning 12 VDC to 28 VDC with modest 3.2 W consumption.
