1 )Ask your local authorities how you can deal with the problem before it comes back to bite you (legally). You cant expect to incomodate hundreds of
people without payback.
2) Dont ask ScienceMadness members as they'll recommend being cautious.

Why not switch the pump off?
Once it has pulled the air out of the flask then all it can do after that is pump vapour and upset the neighbours.

Consider using different solvents? I'd be surprised if ethyl acetate were causing these problems but toluene/chlorocarbons/etc certainly will.

Any drug manufacturer ought to have sufficient capital to procure a better venue. You can make gram quantities of most drugs operating on a much
smaller scale than that.

To remove traces of nasty volatile organic compounds consider leading the off-gasses into something like a catalytic oxidiser, a furnace or an engine
(as was suggested further up in this thread). The catalytic oxidiser method is shown in the video linked below. But be carefull to avoid the explosion
mentioned in the video, so be sure to check out the recommendations at the end of the video.

Actually one thing that should work pretty well is venting the exhaust through a big container of a low-volatility solvent that dissolves everything.
I think polyethylene glycol (PEG 400 or maybe 600) would be particularly suitable.
After a while though you're gonna have one nasty bucket of polyethylene glycol. Presumably this can be disposed of by combustion.

Yup! Folks are complaining? Stinking up the neighborhood? Got laws against that.
You are in legal jeopardy.
Figure out how to cool and trap those vapors.
Dry ice ? An expensive solution, but better than an ominous knock on the door, followed by exorbitant legal fees.

i am not exactly mr. safe myself but if you want to deal with gallons on top of gallons of solvent, just don't do it in a residential area.
