How much is an aerator? Price reference and purchase guide for various types

Oxygen Prices Overview: A Must-Read Before Investing

In the aquaculture industry, aerators are indispensable equipment, which directly affect the amount of dissolved oxygen in the water body, which in turn is related to the healthy growth of aquatic products such as fish and shrimp. However, in the face of a wide variety of aerators and different prices on the market, many farmers are often confused:
How much is an aerator?
This article will analyze the price structure of aerators in detail from multiple dimensions such as type, brand, and performance, and provide practical purchasing guides to help you make informed investment decisions.

Main types and price ranges of aerators

The price of aerators varies according to their working principle, power, material and brand. Here are the most common types of aerators on the market and their approximate price ranges for your reference.

1. Impeller aerator

Impeller aerator is the most traditional and widely used aerating equipment. It drives the impeller to rotate through the motor, agitates the water body and produces water splashes, thereby increasing dissolved oxygen. Its structure is simple, maintenance is convenient, and it is suitable for large fish ponds and shrimp ponds.

• Price Range:
  About 800 - 3000 yuan/unit (1.5kW - 3kW)
  
• Features:
  Oxygenation efficiency is high, suitable for deep-water ponds, but the noise is high and the energy consumption is relatively high.
  

2. Microporous aerator (bottom aeration)

The microporous aerator presses air into the pipeline through the roots fan, and then releases tiny bubbles through the microporous tube to aerate the water body from the bottom. This method can effectively improve the bottom quality and promote the convection of the water body up and down.

• Price Range:
  The complete system (fan + pipe + aeration plate) ranges from about 2000 to 8000 yuan, depending on the power and pond area.
  
• Features:
  Low noise, uniform dissolved oxygen, suitable for high-density farming and shrimp and crab ponds, but the installation cost is high.
  

3. Water wheel aerator

The water wheel aerator drives the water wheel blades through the motor to lift and push the water body to flow, forming a horizontal flow, which is suitable for shallow ponds and cultured species (such as shrimp) that require water flow stimulation.

• Price Range:
  About 1000 - 4000 yuan/unit (1.5kW - 2.2kW)
  
• Features:
  It has strong water lifting ability and can form directional water flow, but its effect on deep water oxygenation is limited.
  

4. Water jet aerator

The water jet aerator (also known as the swell machine) sucks in water and sprays it through the nozzle to form a fountain-like, with oxygenation and ornamental functions at the same time. Suitable for shallow ponds and garden water features.

• Price Range:
  About 500 - 1500 yuan/unit (0.75kW - 1.5kW)
  
• Features:
  Beautiful and can form waves, but the depth of oxygenation is limited.
  

5. Solar aerator

With the promotion of green energy, solar aerators have gradually emerged, which use solar panels to generate electricity and drive aerobic equipment, suitable for remote areas or ponds with limited power.

• Price Range:
  About 3000 - 10000 yuan/set
  
• Features:
  Energy conservation and environmental protection, but affected by the weather, the initial investment is high.
  

Key factors affecting the price of aerator

In addition to the type, the following factors will also significantly affect the final price of an aerator:

1. Power and oxygenation capacity

The higher the power, the stronger the aerating capacity, and the higher the price naturally. For example, a 1.5kW impeller aerator may cost only 800 yuan, while a 3kW one will cost more than 2,000 yuan. When choosing, the required power needs to be determined according to the pond area and breeding density.

2. Material and durability

The aerator is immersed in water for a long time, and the material is crucial. The fuselage made of stainless steel or engineering plastics is more resistant to corrosion, has a longer lifespan, and is more expensive. While cast iron or ordinary steel is less expensive, it is easy to rust and has high maintenance costs.

3. Brand and after-sales services

Well-known brands (such as Tongwei, Zhengbang, Zhongyu, etc.) usually have higher prices, but the quality is guaranteed, and they provide perfect after-sales services. Small brands or miscellaneous brands have low prices, but the failure rate is high and after-sales is difficult. It is recommended to choose brands with good reputation to avoid losing the big because of the small.

4. Additional features

Some high-end aerators are equipped with functions such as automatic control, remote monitoring, and variable frequency speed regulation, which can significantly increase costs, but also improve management efficiency and reduce energy consumption.

How to choose an aerator according to breeding needs?

Buying an aerator should not only look at the price, but also consider the actual demand. Here are some practical suggestions:

STEP 1 Assess pond conditions

Measure the depth and area of the pond. Deep ponds (> 2 meters) are suitable for impeller or microporous aeration; shallow ponds (
