The lower volute works in conjunction with the upper volute to channel air from the fan motor into the combustion area. This lower volute is a durable replacement part for heating equipment components, designed to fit securely and maintain proper airflow. If your boiler or burner is experiencing reduced efficiency or unusual noises, a damaged lower volute could be the cause. Replacing it restores the air path integrity, ensuring your gas burner parts operate smoothly and your heating system runs efficiently.
