That is why more of this Forum is about fume hoods and scrubbers and flow rates than chemistry.

Please post pictures of your vacuum scrubber.

By small I mean less than 500 ml working solutions. When you get into liters or gallons, you are in a different ball game with the fumes produced.

For $1K+++ you could buy one heck of a lot of $40-$50 squirrel-cage blowers which would slowly but relentlessly become destroyed by acrid fumes.
