The QG030-198/14 from EBM-Papst is a DC tangential fan (cross-flow fan) with dimensions of 47.5 × 260.5 × 50.0 mm. It operates on 24 V DC and delivers up to 95 m³/h at free air flow. With its compact, elongated form, it is excellently suited for applications where space is limited but a uniform and wide airflow is required.
The fan is a good choice for control cabinets, medical equipment, display units, and similar applications where quiet and even airflow along a wide surface is crucial. Optional mounting position provides great flexibility for integration.
