Aerator is a kind of machine that is often used in the fish farming industry. Its main role is to increase the oxygen content of the water to ensure that the fish in the water will not be hypoxic, but also to inhibit the growth of anaerobic bacteria in the water to prevent the deterioration of the pool water threatening the living environment of fish. The aerator generally relies on its own air pump to inject air into the water to achieve the purpose of increasing the oxygen content in the water.
Aerator is a kind of motor or diesel engine and other power source to drive the working parts, so that the "oxygen" in the air quickly transferred to the aquaculture water equipment, it can use the comprehensive use of physical, chemical and biological functions, not only to solve the problem of fish floating head caused by hypoxic pond aquaculture, but also to eliminate harmful gases, promote the convection exchange of water, improve water quality conditions, and improve the quality of water. Reduce the feed coefficient, improve the fish pond activity and primary productivity, so as to improve the stocking density, increase the feeding intensity of the breeding object, promote growth, greatly increase the mu yield, and fully achieve the purpose of increasing aquaculture income.

The role of the aerator is not only to increase the oxygen of the water body, but also to effectively promote the improvement of the primary productivity and self-purification capacity of the pond, thus improving the water quality and ecological environment of the pond. The water circulation flow generated by it is not suitable for the living habits of some cultured objects such as eel and shrimp, but it has a good effect on promoting the healthy and rapid growth of fish and shrimp.
Jinhua Dongda Pump Co., Ltd. is a leading manufacturer of stainless steel submersible pumps in China.
