I got the 6" Vortex 449cfm 10 year ect for 179.99 free shipping

Thanks for the tips.
DrGreenBean Reviewed by DrGreenBean on . InLine Fan Shopping, [Elicent, VORTEX, or CanFan] Leaning more towards the Vortex, 449cfm @ 2600rpm 49dBA The other fans spin @ 3200rpm's or better. I would think the lower rpm wouldnt be as loud. My whaling new EcoPlus fan has got to go. I do not want another loud ass fan. I'm going to install a rotary adj light dimmer box inline on the cord if that matters. Any thoughts ideas or suggestions more than welcome. Rating: 5
