Iíve been monitoring for a day, and seen some rather bizarre ideas. Gary's suggestion is a most ideal one. As he stated the regulator is the most expensive and AFAIK the tank is relatively cheap and the gas very cheap. I have ysed this system for decades with great success. I have a couple of compressors (one is a diaphragm compressor-vacuum) and both require extensive moisture trapping and filtration at least for air brushing (I used to make model train stuff).Originally Posted by glbeas
Nitrogen/argon tank gas is almost pure with no danger of entrained water or oil. It is available in most welding shops or directly from the supplier. I have Lindy or whoever deliver to my door.
