Fresh Air Supply-painting

They are good and will protect your lungs, especially if you are using the newer paints. They are what fire departments went to many years ago(FD equipment uses high pressure air bottles these use low pressure fan to supply), positive pressure. Wearing one there is no way that any other gases will enter your lungs because more air is entering the mask than needed and what is not used is bled off through the one way valves, hence the Positive Pressure concept.

I have and use one that I built myself before anything was available, same type of system, just as effective but being cheap, or as a friend said one time thrifty. Mine cost about 150 to build with a 75' air supply hose, so the air intake for breathing is in a safe non contaminated area away from where you are spraying, sanding etc. Before I built this one I used my FD air pack. If you want to build your own reply with a private message here and give me your email and I'll send PICS. Your mileage may vary
