Aquatic Farm Variable Speed Aerator

Our ultra-light variable frequency paddlewheel aerator is an ideal oxygenation solution for large-scale, factory, and recirculating aquaculture projects. It is available in four power grades — 0.55 kW, 0.75 kW, 1.5 kW, and 2.2 kW — to match different pond volumes and breeding densities.

Breaking through the traditional paddle aerator structure, this unit uses a gearless direct-drive motor. There is no gear wear and no oil change work, achieving zero maintenance and greatly reducing operation management workload. The variable frequency drive delivers an obvious energy-saving effect with multi-speed adjustable operation.

The equipment supports wide voltage input and features a phase-loss alarm with non-stop function. When a power fault occurs, it sends an alarm signal and continues working to prevent huge economic loss. An integrated multi-protection system includes lightning protection, anti-winding protection, and overload protection. Soft start reduces mechanical impact, protecting both the frame and the aquatic animals.

The floating assembly can be freely placed in different areas of the pond. The paddle wheels stir the water to enhance oxygen dissolution and vertical water circulation, effectively purifying the water body, reducing harmful substances, and lowering disease risks for aquatic animals. The machine features stable operation, low noise, and long continuous working time.
