A novel fitting for air blowers in air baths that is to be used in conjunction with the blower plumbing system between the blower and the mandated water backflow prevention safety device. The fitting has an internal structure that acts through a dual push/pull effect in order to divert a portion of the air through an ozone generator. The influent side acts as an air ram, like a pitot tube while the effluent side acts as a venturi. The design is symmetrical in that the fitting can be installed in either direction, i.e., the fitting is reversible in relation to the blower.
