The Echo 21250001112 Leaf Blower Nozzle Assembly Misting is an airflow-shaping attachment designed for use with compatible Echo misting blowers. It works by guiding the combined air and mist stream into a focused pattern, allowing controlled direction during outdoor applications. Its formed outlet supports steady distribution, making it suitable for targeted misting or concentrated airflow tasks. The assembly fits the blower’s discharge tube and installs easily during regular equipment setup or replacement.
