China Variable Frequency Surge Aerator

The Permanent Magnetic Variable Frequency Eruptive Aerator
The Eruptive Aerators are state-of-the-art aquacultural facilities which have been well known for easy installation (within 3 minutes), transferable and power-saving. The unique design of flower-shaped spiral impeller associated with ring buoys distinguishes its oxygenic generation principle from traditional impeller and waterwheel aerator. Such design implements a certain area of boiling water by erupting underneath water upwards to simultaneously increase water and oxygen integration, therefore enriches the oxygen volume of pond.
Moreover, the eruption pushes water internally up through motor and controller, which cools down the working heat of both and effectively resolves the current rising caused motor burned out due to temperature rise of longtime running.
Tested by the National Fishing Machine Quality Supervision Center, its oxygen generative capacity is greater than 2.9 kg/kw.h which has been identified as the fastest aerator among similar products with the same power.

Energy-Saving: The aerator uses high-efficient permanent magnet synchronous motor, which is more efficient and 30%-40% power savable compared to the traditional asynchronous aerator.
2. Variable Frequency: The revolution speed of the aerator can be automatically adjusted. Moreover, within a certain range of voltage the running speed is relatively stable while the grid voltage frequency jitters.
3. Stability: Enabled self-protection of phase loss, overload and short circuit to prevent malfunction.

4. Environmental Protection: Pollution-free with no gearbox to refuel for or routinely maintain for.

5. Light Temperature Rise: The temperature rise of aerator motor and controller owing to constantly working in summer is relatively lighter than that of traditional aerator, which extends product's lifespan.

6. Ultra-Quiet: The aerator applied advanced vector control algorithm eliminates electromagnetic and mechanical noise and works ultra-quietly.

7. High Waterproof Grade: With proved IPX7 waterproof grade, the machine can be fully immersed in water for over 300hs in working condition without water leakage and seepage.

8. Wide Voltage Operational Range: The aerator is adaptive to three-phase and single-phase voltage (200-400V, 110V-250V respectively) and safe to use under unstable grid voltage condition.

9. Easy Installation and Maintenance: Lightweight and easy installation, requires only one person to support installation underwater.
