Lighthouse Hydro 240 CFM Duct Booster Inline Cool Air Blower Vent, 6-Inch
This 6" Duct Fan offers an inexpensive and quiet alternative to an Inline Fan. With high quality, all steel construction, this Duct Fan is lightweight and operates as smooth as any fan we've come across. It is extremely quiet and features steel impeller blades and a sealed bearing motor (the ones you find at the hardware store are usually plastic blades and have open bearing motors). Ideal to vent a growing area, or used in conjunction with a carbon filter for odor control.
