5 the typical value for handheld pneumatic power tools would be in the general range of approximately 125 psi or less which is substantially less than the 3 000 6 000 psi range envisioned for the air gas supply vessel 2 of course the pressure used by each tool 5 will vary depending on the particular task the tool 5 is intended to perform the input 9 is preferably a universal adapter which is found on most commercially available tools 5 the advantage of using a universal adapter in conjunction with the air gas pneumatic air supply system is that it allows the air gas pneumatic air supply system to be used with virtually any air powered tool 5 this eliminates the need for any redundant parts and it provides a significant convenience to the workman 1 because the workman 1 needs only to quickly disconnect the high pressure air hose 4 from the tool 5 and then connect it to the next necessary tool as a result the workman 1 is able to carry the small or large lightweight air gas supply system which is conveniently secured to the workman 39 s 1 tool belt and which is always available whenever the workman needs it in this alternative preferred embodiment the air gas supply vessel 2 is secured via a strap 7 to back brace 6 in turn back brace 6 is secured to the workman 1 via straps 8 those skilled in the art will recognize that the back brace illustrated in this figure is for illustrative purposes only and any suitable method.
