Replacement room air wheel drawing interior air into the furnace for circulation over the combustion chamber, restoring efficient heat distribution back into the RV.
The Suburban Mfg 525047 is a genuine OEM replacement room air wheel, attaching to the blower motor on compatible SF and SFV series furnaces. It draws cool air from the RV's interior into the furnace; as this air circulates, it's heated by passing over the sealed combustion chamber and is then distributed back into the living space. This part also supersedes the older part number 350129.
This is the room air wheel, which circulates interior room air over the combustion chamber for heating. It is a separate, functionally isolated component from the furnace's combustion air wheel (used for the sealed burner chamber's intake air), even though both wheels attach to the same motor. If the combustion air wheel needs replacing instead, that's a different part - for example, #350183, #521234, #521235, or #521236, depending on the furnace model.
