Hello all!
My husband just put in a new ventilation system (
http://www.andreaguarino.com/VENTILATION.html) for me but we haven't worried about make-up-air yet.
My question is how to get adequate make-up-air into the studio? There is a door to the outside and 2 small windows. I'd rather not leave the door open, but usually leave at least one of those windows open when I torch, but have heard that isn't enough. I have read so many different things I am just confused!!
My workbench is against a wall - sheet metal on the table and on the wall behind it so putting a vent in the tabletop isn't really an option and my vent goes straight out the wall to the outdoors in front of my torch.
Suggestions?? Advice??
I do need something that can be closed when not in use - New Hampshire winters are COLD!!!!
