Be cool! Enjoy a portable way to cool off, wherever you need it with the active air inline fan. 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. The active air inline fan is quiet running, made with UL recognized components. The eco-themed casing coloring blends in with your leaves, branches, and fronds, but the gentle breeze won't knock over or harm planters and pots.
