This 6-inch inline duct fan is built for grow tents and other small enclosed spaces where stagnant air and lingering odors are a problem. It pushes up to 380 CFM of airflow while staying quiet at 52 dB even at full speed, so it can run through the night without disturbing sleep. A pure copper motor handles long operating hours without overheating and holds up against corrosion, which matters in the humid conditions common to grow tents and basements. The ABS housing keeps the unit lightweight at 4.41 lbs while still standing up to daily use. Beyond grow tents, it works well for basement airflow, kitchen ventilation, and laser engraving fume extraction, wherever a compact fan needs to move a meaningful volume of air out of a small space. The fan measures about 11.81 x 7.87 x 7.87 inches and installs with basic mounting hardware; note that the controller, ducting, clamps, and hanging straps are sold separately, so this listing covers the inline fan unit only.
