a one piece manifold having a front side, a back side, a top side and a bottom side;
an oxygen inlet fitting and a compressed air inlet fitting mounted on the front side;
an oxygen filter and a compressed air filter mounted on the bottom side;
an oxygen regulator and a compressed air regulator mounted into two integrated regulator mounts formed into the top and bottom sides of the manifold;
an oxygen pathway coupling the oxygen inlet fitting to the oxygen filter, the oxygen filter to the oxygen regulator, and the oxygen regulator to an oxygen outlet opening in the back side of the manifold; and
a compressed air pathway coupling the compressed air inlet fitting to the compressed air filter, the compressed air filter to the compressed air regulator, and the compressed air regulator to a compressed air outlet opening in the back side of the manifold.
