Building a fumehood for the chemistry section
- reference board & learning
- design
- build
一
Info, get a lot of pictures and look for design patterns, and sizes. ratios, etc … Also read a lot of quora, reddit, and download a some PDF manuals of commercial fume hoods & copy their dimensions. This puts a lot of weight out of my shoulders as rations and parameters are taken from already proven ratios.
I sketched up my synthesis of all that I’ve seen and liked and ended up with this design:


caveats & challenges:
- chemical resistance of materials in direct contact with the fumes (not every hood is for every chemical!)
- correct ventilator type, because standard ones can’t be used due to the exposure of motor coiling and the bearings leading to a quick motor failure (corrosion)
- the airfoill“ shape
- because I choose PVC laminated wood as a corpus, I needed to fireproof it with a coating
