| 17. An air bath, comprising:
a basin having a bottom and side walls;
an air delivery system including:
a blower;
a plurality of air outlets extending through the side walls in spaced relation;
a conduit extending between the blower and the air outlets having at least one valve therein for controlling air flow to the
air outlets; and
a bypass opening in the conduit downstream from the blower and upstream from the at least one valve in communication with
ambient air for maintaining the blower in communication with the ambient air during operation, wherein the bypass opening
is maintained in communication with ambient air during operation and wherein the opening is of a lesser sectional area than
that of the conduit so as to create back pressure in the conduit such that at least a portion of the air from the blower flows
to the air outlets at least until a threshold water head pressure is reached within the basin.
