Description
ebm-papst 8312HLU is an industrial-grade, IP68-rated DC tubeaxial cooling fan engineered in a compact 80 x 80 x 32 mm (3.15 x 3.15 x 1.26 in) plastic housing. Designed for reliable performance in harsh environments, it operates on a nominal 12 VDC supply (6.0 to 15.0 VDC range) to deliver 39.4 CFM (67.0 m³/h) of airflow at a rated speed of 4,200 RPM with a low power consumption of 4.0 W. The aerodynamic assembly utilizes air exhaust over struts with clockwise rotation and is supported by a precision dual ball bearing system that permits mounting in any shaft orientation. Electrical connection is established via robust AWG 22 stranded lead wires measuring 310 mm (12.2 in) in length.
Key Features
- Environmental Protection: Certified IP68 ingress rating provides total dust immersion and continuous water submersion defense.
- Dual Ball Bearings: Heavy-duty precision ball bearing assembly ensures extended operational life across any mounting orientation.
- Wide Voltage Input: Accommodates dynamic operating supplies from 6.0 to 15.0 VDC with integrated motor control.
- Durable Composite Build: Glass-fiber reinforced plastic housing and impeller provide mechanical rigidity and chemical resistance.
- Standard Lead Hookup: Factory-installed 310 mm AWG 22 color-coded flying leads ensure seamless installation into OEM harnesses.
