New Ventilation Cabinet

Here is our new ventilation cabinet for alchemy, which uses outside makeup air, so as to not pull heated or air conditioned air out of the room and as a backup precaution against venting noxious vapors into the lab.

The makeup air slot is 3/4″ wide and at the bottom of the makeup air plenum, and the exhaust plenum has a 3/4″ inch slot at the bottom, to pick up heavier than air fumes, and a 3/4″ slot at the top for the lighter than air fumes.   The door uses a piano hinge and closed cell weather stripping for a seal.

The veiw window is 1/4″ Lexan.
