EBM PAPST Centrifugal fan RRL152/0020A92-3030LH-197apy 55462.19930

Centrifugal fan by EBM PAPST, model RRL152/0020A92-3030LH-197apy, SKU 55462.19930. It operates at 2200 rpm, delivers 200 m³/h airflow, and has a 150 mm impeller made of stainless steel. Current consumption is 0.19 A, and it uses ball bearings. This fan is designed for supplying combustion air in burners and for flue gas extraction in room-sealed appliances.

When selecting a replacement centrifugal fan of this type, ensure the impeller diameter, rotation speed, airflow, and electrical ratings match the original. The outlet direction and orientation, flange pattern, and control mode (mains, PWM, or 0-10 V) must be compatible with the burner or mixer. Verify the mounting dimensions and compare the part number with the original specification before ordering.

Typical failures include worn bearings causing noise or vibration, impeller imbalance from deposits, a failed capacitor, or speed feedback errors. These issues may lead to reduced airflow, burner lockout, or incorrect combustion settings. Check for unusual sounds, excessive vibration, and error codes related to airflow or speed.
