This is a replacement room blower assembly designed for the Comfortbilt HP21 pellet stove. The room blower circulates heated air from the stove into the living space, ensuring efficient heat distribution.

Both versions are complete assemblies, including the motor, fan cylinder, and mounting bracket.
