Ok one night I was trying out spray painting inside the spray booth. Turns out whenever I spray the overspray(at least the fumes) were coming straight towards my face!
It was visible when a light was shine through the booth opening. Apparently the fumes were first directed out of the booth, and then they raised slightly, and became invisible due to the fumes being dissipated. However, the instant decrease in fume smells shows that the fumes were in fact being sucked into the fans.
From that I could tell the air near the fans are being rotated around, outwards at the bottom of booth, then upwards at the top of the opening of the booth, then the air is being pulled into the booth and down the fans.
(I hope whatever that I just said makes sense to most of you here. Its hard to catch the movement of air within a picture)
Could the arrangement of my fans cause the air to circulate improperly? From the experiences of you guys, how would you rearrange the locations of the fans to prevent the paint fumes from blowing back out the booth?
Thank you in advance.
P.S. I already taped the exhaust duct onto the fan box, and I am going to keep the booth being made entirely out of cardboard for now. Thanks for the suggestions from the previous people
