Abstract

An improved more compact type of fully adjustable spa jet water aerator is provided which is simple, inexpensive, durable, easy to install and use and which features easy separate adjustment of water and air flow therethrough. The aerator can be secured within a spa wall with the exit nozzle and controls readily accessible from within the spa. The aerator comprises a molded unitary housing defining an elongated passageway with water and air conduits disposed in stacked relation on the same side of the passageway to conserve space. The passageway extends to the front of the housing. The conducts have openings communicating with the passageway and a concentric pair of sleeves are threaded into the passageway and manually adjustable to align apertures therein with the conduit openings to control the air and water flow into the passageway. Cylindrical preferably ridged seals with alignable apertures are disposed over the rear ends of the sleeves adjacent the sleeve apertures to prevent fluid leakage. The inner sleeve defines an aerating chamber, and a replaceable flow reducer cylinder is disposed adjacent thereto in the inner sleeve.
