Regular circular fan + duct for exhaust?

Anyone have a reason why this setup wouldn't work? I was planning on using a regular personal fan, like such:

And getting some 6" duct attached to the back of it to be my exhaust fan. In other words, the duct would go from my light, out the grow box, and then be sealed to the rear of the fan.

Iv'e only seen one other person using a regular fan for this purpose (though his duct was on the front of the fan, so it was a "push" setup rather than a "pull" setup).

Wouldn't this have a similar effect as an inline fan, or am I missing something? I know there isn't a cfm rating, but I would assume it's pretty high.

Thoughts?

get a 6" inline duct fan, thefan baldes impellers are designed for such use, the fan you posted isnt designed for duct usage, you can pick up a 6" inline for nearly the same price.

Really? All I can find near that price range are booster fans, which i've heard are no good alone, only for their intended "booster" effect.

All the actual exhaust inline's are $90+

Don't want to be a cheapass, but honestly I have a hard time dropping $70 more on something that will have a similar effect. Unless of course I am way off in thinking it will work the way I am imagining

A booster fan will do much more good than attaching duct to a random fan.

booster fan has flanges on each end and are rated at free air flow as well as boosted air flow, just not good for pulling through a filter.

inline fans are designed to work against resistance, much like a turbo. It's not just spinning to move air, it's designed to create suction and pressure. Those table fans can't do that.

put your hand on the back of that table fan there is NO suction it won't do shit. if you do that on an inline fan it will probably suck ur hand into the blades. point proven stop being cheap end thread.

Thanks, that's the kind of answer I was looking for.
