Be cool! Enjoy a portable way to cool off, wherever you need it. Bring the chill inside to your grow room, kitchen, or other warm areas with the Active Air In-Line Booster Fan. The fan props up on its own and can work as a standalone or may be mounted in-line with your existing ductwork to increase airflow. Available in 6", 8", and 10" models. Active Air fans are quiet running, made with UL-recognized components, and include an 8', 120v power cord. The eco-themed green casing coloring blends in with your leaves, branches, and fronds, but the gentle breeze won't knock over or harm planters and pots.
