Mecale Inline Duct Fan 6 in 400 CFM AC Motor with Variable Speed Controller

This 6 in inline duct fan moves up to 400 CFM and uses a durable AC motor with thermal overload protection. It features a stepless variable speed dial for precise airflow so you can dial in the right airflow for your space. A mixed flow impeller builds static pressure up to 300 Pa to push air through long duct runs and bends. It works well for grow tents, hydroponics, kitchen and bathroom exhaust, workshops, and booster fan installs.
