10 – 300m3/H Fine Bubble Membrane Diffuser Disc Diffuser Submersible Aerator

Submersible Aerator

Product Overview

The Submersible Aerator is an efficient aeration device designed for wastewater treatment, aquaculture, and industrial water systems. It is installed directly in the water and delivers high oxygen transfer efficiency with low energy consumption. Its submersible design ensures stable operation, easy maintenance, and quiet performance, making it suitable for aeration tanks, ponds, and lakes.

Working Principle

• The motor drives the impeller to rotate, generating a vortex in the water.

• Water flow is mixed with air, forming fine bubbles that increase dissolved oxygen levels.

• Oxygen-rich water circulates throughout the tank, improving biological treatment efficiency or water quality.

• The submersible design allows the aerator to operate underwater without additional structures.

Main Components

• Submersible Motor: Waterproof and corrosion-resistant, drives the impeller

• Impeller / Rotor: Generates water movement and air diffusion

• Diffuser (Optional): Produces fine bubbles for efficient oxygen transfer

• Protective Housing / Frame: Stainless steel or coated for corrosion resistance

• Power Cable: Waterproof and flexible for submersible operation

• Support / Mounting System: For tank or pond installation
