Fume extraction in workshop

Hi all, I am currently building the sheet press system. I also made an extruder and injection machine in the past. Since the machines produce a lot of (toxic) odors I would like to have some advice on good fume extraction. Does  anybody has some good solutions for it, are there standard machines on the market that are sufficient?

 

I am curious what kind of solutions others have found? I think for the Sheet press you will need quite a heavy duty machine. Does anybody also filter the air or just extract it outside?

There are several threads on this issue like this http://onearmy.world/community/forums/topic/v4-fume-extraction-4/  . Looks like the V4 efforts finally started to address safety in some of the designs and documentation https://preciousplastic.com/solutions/machines/overview.html .
If you have 3 machines going at once, I would make three fume hoods extracted by a common fan and ducting. Whether you filter the exit probably depends on your local situation
