Nope. These types of fans ("can fans") do not have enough power to push air through a carbon filter. No reason for a speed controller, they run quiet and do not have a high output relative to a squirell cage blower or a high velocity inline fan, both of which can be used with a speed controller and/or carbon filter.
Would this fan work for a small box that doesn't need a scrubber or filter though? I'm making a 3x3 for my veg room, and since it's legal, I'm not worried about smell, just the air-flow...

yah it would definately work. You need to figure out how many cubic feet your growing area is and then get at least twice as much cfms on your fan. More is better.
These fans are crappy at best, I bought one before I bought my big boy fan, and I can tell you this, if you need it for anything other than air exchange forget it..
This fan's main purpose is to boost air thats already moving, so that rating of 160cfm, was probably already 140cfm before it entered the fan..
