Propeller De Dietrich 7804320

A propeller is a fan blade assembly used in heating equipment to move air for combustion or ventilation. In burners and boilers, the propeller is typically attached to a motor shaft and creates the airflow needed for proper combustion or heat distribution. Over time, propellers can become unbalanced or damaged, leading to noise and reduced efficiency. Replacing a worn propeller restores optimal airflow and system performance. It is important to choose the correct size and pitch to match the original design.
