Description
ebm-papst 4314 is an industrial compact DC axial cooling fan measuring 119 x 119 x 32 mm (4.69 x 4.69 x 1.26 in) engineered for forced-air cooling in electronic enclosures. Operating on 24 VDC across an input window of 12 to 28 VDC, it delivers an airflow of 100.1 CFM (170.0 m³/h) at a rated rotational speed of 2800 RPM while consuming 5.0 W. The mechanical assembly utilizes a glass-fiber reinforced PBT plastic housing and glass-fiber reinforced PA plastic impeller supported by precision ball bearings. Electrical connection is provided via AWG 22 TR 64 lead wires, and the brushless motor includes integrated protection against reverse polarity and locked-rotor conditions.
Key Features
