Good Morning folks, I have been searching the forums all morning seeking an answer to my question. Given the space I have to work with, which is a small 'storage' room in my basement, I will be venting to the outside. I am concerned with creating a negative pressure in my house, it's a pretty tight envelope. I will have a sacrificial basement window in which to run the vent externally. I am wondering if anyone has introduced an intake vent to their laser from the outside air to mitigate conditioned air loss as well as negative pressure. Pics would be awesome if anyone has them.
