ABSTRACT:
Apparatus and methods include an array of a plurality of individual air injector nozzles are integrally connected to a common air flow tube. The individual nozzles include an integral attaching plate and an integral air injector tube in addition to the common air flow tube with the individual nozzles spaced along the common air flow tube. A plurality of arrays can be joined together to form an entire arrangement of any desired configuration of individual air injector nozzles that can be applied as a complete unit to a tub or spa. One or more of the arrays can be cut across the common air flow tube to achieve the exact number of individual nozzles required in accordance with the desired arrangement of air injector nozzles. The arrays, including the cut arrays can be joined together at a location other than at the tub or spa and then transferred as a complete unit to be attached to the tub or spa. The plurality of arrays can be joined by a straight or angled connector fitting that can comprise a separate connector fitting or an individual air injector nozzle having air flow tubes arranged in the straight or angled configuration.
