I'm looking for a small affordable fan blower about 6-8" any size really
does anybody know where to find one?
I really don't want to sit down with computer fan and a soldering iron.
You should be able to get a duct fan at any home improvement center. You just might have to buy an appropriate power cord and wire it yourself. The product Beansly referred to is probably pre-wired.
Home Depot, Lowes and Maynards should all carry an inline duct fan. cost between 25 and 45.00 for a 4 inch, 6 inch, or 8 inch duct fan. 250cfm on the 4 inch fans.
