Has anyone used these blowers / fans?hello all i found this the best fan ever i use the td 150 for a 4'wx7'lx8'h basement area 1 600w and i only use half power on a speed controll http://www.fjevans.com/TD-Series.1.339.html these fans are very quiet especially if mounted w/ rubber tie downs the fan has amazing high air flow to pressure ratio meaning you can use a y and vent multipal rooms no problem enjoy and keep em green, hope this helps ...
