Description
ebm-papst 5314/2HP (also cross-referenced as 53142HP) is an industrial-grade DC Axial Fans tubeaxial cooling fan engineered for high-density forced convection cooling, measuring 139.6 x 139.6 x 50.8 mm (5.50 x 5.50 x 2.00 inches) and operating on nominal 24 VDC. The unit delivers a maximum unimpeded volumetric airflow of 203.0 CFM (345 m³/h / 5.68 m³/min) and up to 280 Pa (1.12 in H₂O) static pressure at a rated rotational speed of 5000 RPM while consuming 28.4 W. Constructed with a die-cast aluminum frame and a fiberglass-reinforced PA plastic impeller, the assembly provides high structural rigidity against vibration and mechanical stress. Drive functionality is maintained by an electronically commutated external rotor motor supported by dual precision ball bearings for unrestricted multi-axis mounting orientation. Electrical interface is executed via three discrete 310 mm lead wires with integrated open-collector tachometer frequency monitoring, backed by locked-rotor protection and reverse polarity defense.
Key Features
- High-Flow Aerodynamic Output: Delivers 203.0 CFM (345 m³/h) and up to 1.12 in H₂O (280 Pa) static pressure to overcome dense flow resistance in ducted electronics.
- Die-Cast Metal Frame Construction: Built with a rugged die-cast aluminum housing and UL94 V-0 fiberglass-reinforced impeller for harsh industrial duty.
- Precision Dual Ball Bearings: Engineered with premium dual-race ball bearings ensuring continuous S1 operation and extended L10 service life across -20°C to +65°C.
- Integrated Tachometer Output: Outfitted with an open-collector speed sensor (/2 suffix) generating discrete pulses per revolution for automated RPM supervisory control.
- Comprehensive Motor Protection: Incorporates active electronic reverse polarity defense and automatic restart lockout protection in stalled rotor conditions.
