Hi kmann, welcome to the forum.
Your fume hood won't hold up to hcl, or Ar.. Here's why. The interior is stainless. The motor is steel , it blows downward through stainless grates, one in front and one it back on the floor of your bench. The fumes go up the back cavity across painted steel into the steel motor. From the motor it blows down the aluminum lined large filter and out the aluminum lined small filter. Aluminum and hcl don't work together. Both filters are aluminum grates lined with paper, then glass fiber..they are housed by the steel painted walls of the hood. If you look inside, up. The UV light will rot as it's exposed as are the copper control wires ( no nitric here), if you were to throw some elbow grease and dollars at it, it may work. You may be better off getting the right kind of hood for next to nothing. Pick your purchases with the application well in mind or consider the latter, money spent on something that will be junk in a matter of weeks. , Jonn.
