A portable floating apparatus for providing pressurized air to a submerged diver. The apparatus is comprised of the combination of a gasoline engine and an air compressor, said combination being housed in a buoyant container similar to a suitcase. The gasoline engine is preferably a two-stroke engine which drives the air compressor. The top of the container has large outlets for the intake of fresh air for compression, engine cooling and the exit of exhaust gases. These outlets have cowlings extending therefrom to reduce flooding by water from spraying or waves in rough seas. A small outlet on the side of the container with a coupling allows a flexible hose to supply air to a submerged diver. An optional fan may be inserted in the duct of one cowling to provide additional ventilation and cooling. The air supply hose, cowlings and other exterior components can be stored in the container when not in use. A handle is affixed to one side and feet on the opposite side of the container to allow the container to be carried or rested on its side in the same manner as a suitcase or briefcase. Thus, this apparatus is self-contained, compact and lightweight, unlike any such prior devices.
