<p>PURPOSE: Provided is an aerator with increased endurance and lifetime, the aerator being capable of minimizing compressed air and air pressure loss caused due to rapid expansion by keeping internal and external temperatures of a compressor constant, thereby supplying a large amount of compressed air with high pressure into deep sea, and the aerator being preventing rising of sea water temperature by supplying cooled compressed air into the sea water, thereby providing an adequate environment, temperature and dissolved oxygen, for fish culture. CONSTITUTION: The aerator includes a compressor(10) for compressing external air by being driven by a motor(5), an air tank connected to the compressor(10) for storing compressed high pressure air therein and having an air distribution nozzle(30) at a side thereof, a cooling device(40) provided to surround the compressor(10) and the air tank and through which cooling media is circulating, and a pump(50) for circulating the cooling media through the cooling device, wherein the cooling device(40) cools down the compressor(10) and the air tank to increase amount of compressed air and pressure in the air tank and to discharge cooled compressed air to sea water with high pressure through the air distribution nozzle(30).</p> |
