the sponge should be in front of the fan, to keep the fan clean and maximise airflow
my first DIY spray booth I used computer fans, it does work, but not so efficient, especially worse when come to spray cans
if you ever been to Low Yat Sri Computer, the place where they sell the fans, I bought the largest and noisiest fan there

worse come to spray can, means the spray is too fast/ strong that the suction is not strong enough to flow out all the fume?

I still have 1 pending project which will use all the spray cans...

(will buy AB afterward)

yep, from front: filter, 2xsponge, then fan. Tested the exhaust b4, even though 3 layers, suction is still strong.
just started AB, filter can see very dirty liao, but once I remove the filter, can see the sponge still very clean.
so can say that air that comes out from the exhaust are clean without paint.
hee hee, i'm thinking as long as the fume was sucked out, dun care liao, as long as it doesn't jam my fan
