Draft inducers start the exhaust airflow inside a furnace or heater by turning on before a heating cycle. This process removes any stale or contaminated air from the combustion chamber and helps to draw in oxygen, improving heating efficiency. This process also helps ensure that exhaust gases are routed through the exhaust system rather than potentially contaminating the interior space. Exhaust draft inducers install into exhaust ductwork and supplement the existing equipment and exhaust airflow. Replacement furnace and boiler draft inducers are manufactured to match OEM specifications and act as direct replacements for damaged or worn OEM equipment.
