i used a stanley blower that is very similair in design... $40 at walmart, and it has 2 grounded outlets on the unit

3 settings - 1200, 1500, and 1800 cfm labeled as 1,2,3 - had to make a call to the manufacturer to find out the cfm ratings :P
i used it for years and it worked great / still works great but the noise got annoying so i have switched to cpu case fans, which cool the cabinet great as long as i dont use a carbon scrubber (too much drag) so my odor control was switched to ozone and all has been well
