The gas entrainer is a rotodynamic machine for trapping and dispersing bubbles of air into a pool of water. A flat circular disc is mounted for rotation close to and concentric with one end of an open cylindrical tube of equal diameter to form an annular nozzle therebetween. Upon the disc and tube end being immersed in water, the spinning disc draws air down the tube and out through the nozzle to disperse it as fine bubbles into the pool. The faster the disc is spun, the more air bubbles are produced; and this at a considerable depth of water. The disc or rotor employed is without blades or paddles and accomplishes entrainment simply by viscous friction between the disc and water in combination with the closely spaced tube end.
