The Mars Hydro 6″ inline duct fan is rated for 402CFM, sufficient for grow tents or grow rooms measuring up to 5×5 ft. With a knob fan speed controller, the inline fan speed can be adjusted from the lowest to the highest by a simple turn of the knob. Featuring an EC-powered motor and a mixed-flow design, the Mars Hydro inline fan is quiet enough to run at full power with only 32 dBA of noise.
Designed for efficient air filtration, the inner core of the Mars Hydro carbon filter was made of 1050+ Australian activated charcoal, eliminating undesirable odors, pungent smells, and particulates from indoor grow tents. The double-sided galvanized steel mesh provides 53% of the open area for airflow to pass through, so that the odor absorption and chemicals elimination process can be carried out thoroughly. (The carbon filter was covered by a prefilter cloth; do not remove it when using)
Package Includes: 6″ Inline Duct Fan with a knob Speed Controller, 6″ Carbon Filter, 2 Hanging Straps, 25-ft-long Flexible Ducting, and 3 Duct Clamps.
