Inline Duct Fan for Ventilation, 4-, 6- or 8-Inch Options
Size-specific airflow for compact ventilation systems
This inline duct fan range is designed to move air through compatible ducting in grow tents, basements, workshops and other enclosed indoor spaces. Choose the 4-, 6- or 8-inch size according to the duct system and required airflow. The stated maximum airflow is 180 CFM for the 4-inch model, 380 CFM for the 6-inch model and 720 CFM for the 8-inch model.
Each fan uses a pure-copper AC motor in a black ABS housing. Basic options include the fan, user manual and installation hardware. Kit options add two pipe clamps, two suspension straps and an approximately 8 ft double-layer aluminum-foil duct for the selected size. Verify the exact selected option name and package image before ordering.

Installation notes
Select a fan that matches the duct diameter. Disconnect power before installation or cleaning and follow the supplied wiring and mounting instructions. Support the fan independently rather than allowing ducting to carry its weight. Noise and airflow in an installed system vary with duct length, bends, restrictions, filters and mounting surfaces.
