The W1G172-EC95-01 from EBM-Papst is an EC-driven axial fan with a wall ring, designed for demanding ventilation applications. The unit measures 222 × 222 × 79 mm and is equipped with a single-phase EC motor (M1G055-BD) with a rated voltage of 115 V AC and support for 50/60 Hz frequencies. With IP55 protection and an ESM fan housing made of PP plastic, it is built for harsh environments.
The fan is ideal for industrial and ventilation systems where reliable, energy-efficient 24/7 operation is required. The two speed settings provide flexible control of airflow depending on operational needs.
- Maximum airflow: 510 m³/h at free flow
- Two speed settings: 1,700 and 2,500 rpm
- Sound pressure level: 54 dB(A)
- IP55 protection – resistant to moisture and dust
