Abstract

A device for aerating a body of liquid comprising an upper portion and a lower portion, the upper portion being a conduit formed of a flexible plastic material with a plurality of apertures formed therein, the apertures being sized to substantially prevent passage of liquid therethrough while permitting passage of low pressure gas, the lower portion comprising a ballast which is welded to the upper conduit. The device may be utilized for aerating water gardens, ponds, sewage basins, and the like.

Claims

1. A device for aerating a body of liquid, said device comprising:

an upper portion and a lower portion;

said upper portion comprising a conduit formed of a flexible plastic material, a plurality of apertures in said conduit, said apertures being sized to substantially prevent passage of the liquid therethrough while permitting passage of low pressure gas therethrough; and

said lower portion comprising a ballast, said ballast being welded to said upper conduit.

2. The device of claim 1 wherein both said upper conduit and said ballast are formed of a like material.

3. The device of claim 2 wherein said material is a PVC.

4. The device of claim 3 wherein said apertures are substantially circular in configuration and have diameter of between one and three millimetres.

5. The device of claim 1 wherein said upper conduit has at least one protrusion extending exteriorally thereof, and said ballast has a recess sized to receive said protrusion.

6. The device of claim 5 wherein said protrusion comprises a continuous tennon and said recess comprises a mortise.
