Patent ID: 7578292

Claim:
Compressed air system, comprising: a plurality of vessels containing compressed air; a compressed air access station; a control panel located at said compressed air access station and including electrical pressure display and electrical switch means; a plurality of first air conduits connecting each of said vessels to one of a plurality of electromechanical shut-off valves; a plurality of second air conduits leading from an output side of each of said electromechanical valves to a single main air output line, said output line leading to pressure regulator means located at said air access station; a plurality of pressure transducers located on each of said first air conduits, said transducers including electrical signal output means responsive to the pressure in each vessel, each of said electrical output signals from each of said pressure transducers connected to said display means at said control panel; and said electrical switch means on said control panel electrically connected to each of said electromechanical shut-off valves such that compressed air fed to said main air output line may be switched from one vessel to another.
