The Bosch-78184 is a combustion blower assembly that supplies combustion air to the burner and drives flue gases through the heat exchanger and vent on compatible HVAC heating equipment, running on 115/120V AC at 60 Hz. Manufactured by ebm-papst in Germany as model RG128/1300-3612-020304, it uses a die-cast aluminum volute housing that holds the oval discharge flange, inlet tube, and mounting bosses in their original factory positions, so the unit seats and seals against the appliance exactly as the part it replaces without adapters or drilling. The enclosed motor section carries keyed multi-pin connectors for a direct plug-in electrical connection, and the assembly arrives with the flange gasket, O-rings, sealing plate, mounting screws, and rubber vibration-damping blocks needed to complete the swap in one order.
