This turbo fan is commonly used in the assembly of air conditioners and dehumidifiers. The fan is used to draw air through the unit and move it forward into your home. If your fan is cracked, broken, or damaged, it will impact the efficiency and effectiveness of your appliance. If your dehumidifier is loud during its cycle, or the coils are icing over, the turbo fan could be the issue. This fan assembly is made of black plastic, has an outside diameter of approximately 8 inches, and it is sold individually. This is an authentic OEM replacement part sourced directly from the manufacturer.
