A furnace baffle is an important component of a furnace that helps to direct airflow in the system. It is typically made of metal and is installed inside the furnace. The purpose of the baffle is to control the air flow within the furnace, ensuring that the air is evenly distributed throughout the entire system. This helps to ensure that the furnace is running efficiently and that the air is being circulated properly. The baffle also helps to reduce noise from the furnace, as it helps to muffle the sound of the air moving through the system. Additionally, the baffle helps to reduce the amount of dust and debris that is drawn into the furnace, which can help to extend the life of the furnace. In short, the furnace baffle is an essential part of a furnace, helping to ensure that the system is running efficiently and safely.
