Paddlewheel Aerators for Aquaculture

Fuwei’s paddlewheel aerators are surface aeration devices widely used in fish ponds, shrimp farms, and aquaculture facilities. They work by rotating motor-driven paddle blades across the water surface, agitating and splashing water to increase dissolved oxygen levels and promote water circulation — essential for high-density aquaculture where natural oxygen supply falls short. At the core of every unit is Fuwei’s self-developed electric motor, driving paddle blades mounted on a rotating shaft to transfer atmospheric oxygen directly into the water.

Unlike aerators built with off-the-shelf motors, every Fuwei aerator is powered by in-house motor technology — the same expertise behind 100,000+ units shipped annually across 7 product series — tuned specifically for aquaculture conditions: high humidity, continuous 24/7 operation, and exposure to corrosive pond environments.
