Trane FAN3748 Fan Blade-3 19" Diameter 31 Degree 1/2"

The Trane FAN3748 is a replacement fan blade made to blow air in Trane HVAC systems. This critical component is 19" in diameter with angled blades at a 31-degree pitch. The angled shape works well to push air outwards as the blade spins at high speeds, powered by the system's motor. The airflow, then, is funneled into the ductwork, where the conditioned air is funneled through your home. The 1/2" hole on the fan blade is designed to make a tight attachment to the motor shaft. The Trane fan blade is a replacement part for your Trane HVAC system, suitable for long use.
