The QG030-353/14 from EBM-Papst is a DC tangential blower designed for efficient and even airflow along the entire unit. Measuring 415.5 × 47.5 × 50.0 mm and featuring a cross-flow design, it delivers up to 155 m³/h at 3800 rpm. The voltage range of 16–28 V DC makes it flexible for various applications.
The tangential blower is ideal for applications requiring even air distribution over a longer surface, such as in heat pumps, air conditioning systems, fan heaters, and electronics cooling. Its compact profile and optional mounting position facilitate integration into confined spaces.
