  • Patent number: 11318426
    Abstract: A submersible aerator includes a hollow cylindrical housing having an open upper end, an open lower end and a hollow interior. An air supply hose extends from an air supply source into the upper end of the housing and terminates at an air outlet, immediately above the lower end of the housing. Attached to the interior surface of the housing outer wall are a series of vertically spaced, oppositely facing baffle plates that provide impact surfaces to cleave rising air bubbles into smaller bubbles. A weep hole is formed on the outer surface of the air supply hose, equidistantly positioned between each adjacent pair of baffle plates. Accordingly, excess air pressure will be relieved via the weep holes as opposed to the lower end of the housing to protect nearby external equipment.
