EBM PAPST Centrifugal fan G1G170-AB31-01 55600.01061

The EBM PAPST G1G170-AB31-01 is a centrifugal fan designed for combustion air supply in burners and boilers. It operates at a rotation speed of 5650 rpm, draws a current of 2.15 A, and delivers an airflow of 370 m³/h. The fan measures 257 mm in width, 176 mm in length, and 273 mm in height. This model is identified by SKU 55600.01061.

When selecting a replacement fan of this type, key parameters include required air flow and pressure at the operating point, direction and orientation of the outlet, impeller diameter, supply voltage, and control mode (mains-frequency on/off, PWM, or 0-10 V analogue). The flange pattern and mounting dimensions must match the existing installation. Ensure electrical connections, especially the speed feedback signal, are correctly wired.

Typical failure modes include worn bearings causing noise or seizure, imbalance from debris on the impeller, a failed start/run capacitor, or speed feedback faults that the boiler interprets as an airflow failure and locks out. Check for unusual noises, vibration, or error codes related to airflow.
