Variable-Frequency Floating Aerator
A floating aerator built around a variable-frequency drive: soft start removes start-up impact and surge current, while adjustable speed lets you tune oxygen delivery to season, stocking and time of day. Sized for standard pond farming on existing three-phase power, it oxygenates 4–12 mu per unit with a 1.5–3 kW induction-motor core and comes with a 1.5-year warranty.
Features
- VFD soft start suppresses start-up inrush — no surge on your three-phase supply, gentler on the motor windings
- Adjustable speed on demand: run at the rpm your pond needs today instead of flat out
- Built on a standard induction motor with an external VFD — inexpensive, retrofit-friendly service anywhere
- Float-mounted: set up in minutes and move between ponds with no civil works
- Oxygenation capacity 4–12 mu per unit at ≈ 3 kg/h (1.5–3 kW motor core)
- Runs on standard 220–380 V / 50 Hz three-phase power
- 1.5-year warranty with spare parts support

Rated by aquaculture farms worldwide
The ZXMSR blower has run two full seasons without a single stop, and the factory layout support was excellent.
We switched eight ponds to microporous tubing — electricity dropped by about a third and the crop grew through the hot season.
Frequently asked questions
What does soft start do on this VFD floating aerator?
The variable-frequency drive ramps the motor up smoothly, so there is no start-up impact and no surge current on your three-phase supply - gentler on the motor and on the farm wiring.
Can I adjust the aeration speed to match the pond?
Yes. Adjustable speed is the point of the VFD: turn oxygen delivery up in summer or at high stocking density, and down in cooler months or at low load, instead of running flat out all the time.
Which ponds is this model intended for?
Standard pond farms with existing three-phase power (220-380 V / 50 Hz) that want VFD control at a conventional price point. One unit covers roughly 4-12 mu of pond.
What is the oxygen delivery of the 1.5-3 kW unit?
About 3 kg of oxygen per hour on the 1.5-3 kW motor core, which is why one unit comfortably covers 4-12 mu for normal stocking.
How does this compare with the permanent-magnet VFD model?
This model wins on purchase price and works on any standard three-phase farm. If your site runs aerators for long hours at high electricity tariffs, the permanent-magnet model saves more on energy over time.
