QG030-303/12 ebmpapst 12V 0.73A DC Cross-flow Fan

Description

The ebmpapst QG030-303/12 is a high-efficiency 12 VDC industrial DC cross-flow fan, engineered for continuous thermal regulation in demanding environments. This unit utilizes a precision-engineered multi-blade aluminum impeller driven by a high-torque brushless DC motor, which maintains a powerful 8.76 W power profile for wide-area uniform air displacement. Its structural integrity is anchored by an extruded aluminum housing with plastic side parts and a specialized hybrid bearing system—utilizing ball bearings for the motor and a sleeve bearing for the impeller retaining plate—ensuring exceptional mechanical longevity. The 2-wire configuration provides a streamlined and dependable electrical connection ideal for high-reliability systems such as laboratory equipment, telecommunications racks, and large-format printing heaters requiring uniform temperature distribution and a low-profile footprint.
