  • Powder Coat Paint Hopper Design

    I've seen several videos around about how to build a small hopper using PVC and injecting air through a coffee filter or some other membrane on the bottom. None of the designs explain why the professional units have 3 or 4 air connections. Furthermore, some use one or two venture valves. How does all that come together and where does the vacuum come into play? A picture would surely go a long way in explaining how it works.

    Here's a basic picture, based around a professional/industrial gun, which is the correct design. If you are using anything less than that, this will likely not serve your purpose.
