I’m building a fuming hood out of acrylic (also known as “plexiglass in some places).
I wanted to ask the more experienced guys in here if anyone could help me with some details, maybe a plan for building it. Especially at the door: a sliding one or a flipping one? I agree sliding is better, but how you do the sealing on it, and also the system to stop at a certain height? Also, the Mercury vapors are heavier than air, so they’ll get to the bottom of the box; do I have to make a bevel there, so they don’t get out of the box? If yes, how big? When you turn on the fan, where is the air entering the box? (I assume in the bottom, as long as there should the Hg vapors concentrate).
I bought a fan for ventilating pubs with a debit of 280 cube meters per hour (through a pipe of 125 mm diameter). I was wondering if that’s enough, though it sounds good to me. I know it’s not a professional chemical resistant fan (those are WAY too expensive), if it breaks I don’t really care, I’ll buy another one.
It would be a pity that this forum, full of so much useful information, to just disappear.
Hoping that someone will hear my call, thank you in advance,
