Can I use 4 inch can fan rs4 with can filter 33?

[G420]

I'm looking to use an over sized can filter 33 with my little 4 inch can fan so I can be sure that I wont have problems with the smell. Will this work? Will a 4 inch flange fit on a 33? The filter and fan would be used outside the tent. Thanks

Sure, the slower air speed will help the carbon kill the smell. I run a 6in on a 33 for my drying room, works great! Might need the 6 in flange on the filter and a 6-4 reducer for the fan.
