In fact, in the source water treatment stage of the factory-style recirculating water system, fan aeration can remove excessive harmful substances such as chlorides and hydrogen sulfide from the water source.
During the tail water treatment stage, fan aeration can provide sufficient oxygen for microorganisms, accelerating the decomposition of organic matter in the tail water.
In the aquaculture stage, the aeration of the fan can supply enough oxygen for the cultured organisms to breathe, making high-density aquaculture possible.
It can be said that fans play a crucial role in the entire cycle of the factory-style recirculating water system.
Currently on the market, the main types of fans commonly used in recirculating aquaculture farms are Roots blowers, turbo blowers, and high-speed centrifugal blowers.
Here, let’s mainly distinguish them from two aspects: performance and economy.
In terms of performance indicators, Roots blowers have very high air outlet pressure and air volume, suitable for pools with a depth of more than 2.5 meters, such as large biochemical filter barrels.
Turbo blowers have a large air output, but the air pressure is lower than that of Roots blowers. Currently, they can be generally used in front-end fish ponds and rear biochemical filter ponds that are not so large in volume.
For high-speed centrifugal blowers, due to their working principle, although the air volume is far greater than that of Roots blowers and turbo blowers, the air pressure difference makes them not suitable for pools higher than 2.5 meters. They are generally only suitable for fish ponds.
In terms of price indicators, although the overall market price of Roots blowers is more competitive, followed by turbo blowers, and centrifugal blowers are the most expensive. However, due to the design principle, the service life of Roots blowers is the shortest among the three.
To sum up, based on the working principles, performance indicators, and application scenarios of the three types of fans, if the biochemical system of the recirculating aquaculture farm is deep and large, choosing a Roots blower is the best option.
If the diameter of the fish pond in the aquaculture farm exceeds 8 meters, it is recommended to use a centrifugal blower for the fan matching such a large-diameter fish pond.
If the diameter of the fish pond in the recirculating aquaculture farm is not large and the water depth of the biochemical filtration system is less than 2.5 meters, it is recommended to use a turbo blower, which is the most cost-effective.

Air suspension centrifugal blower
Air suspension centrifugal blower is a new type of high-tech blower, which has many advantages: the working principle adopts three core technologies: ultra-high-speed direct-connected motor, air suspension bearing and high-precision single-stage centrifugal impeller.
