Description
Aero-Tube® Ring Diffuser – 300mm Diameter | Microbubble Oxygen Diffuser for Aquaculture & Fish Farming
High-Efficiency Microbubble Aeration for Tanks, Hatcheries & Aquaculture Systems
The Aero-Tube® Ring Diffuser is a compact, highly efficient microbubble aeration system designed to deliver superior oxygen transfer in aquaculture tanks, fish farms, hatcheries, recirculating aquaculture systems (RAS), aquaponics, and aquatic holding facilities.
Manufactured using premium Aero-Tube® micro-porous diffuser hosing, the ring diffuser produces a dense cloud of ultra-fine oxygen bubbles that remain suspended in the water longer than conventional aeration systems. This increased contact time allows more oxygen to dissolve into the water, improving dissolved oxygen levels while reducing energy consumption.
Its circular design provides uniform oxygen distribution across the entire aeration zone, helping eliminate low-oxygen areas and creating healthier conditions for fish, prawns, crustaceans, and other aquatic species.
Whether you’re operating a commercial aquaculture facility, ornamental fish system, quarantine tank, broodstock facility, or hatchery, the Aero-Tube® Ring Diffuser offers a reliable and cost-effective solution for maintaining optimal water quality.

Why Choose the Aero-Tube® Ring Diffuser?
Traditional air stones and coarse bubble diffusers release larger bubbles that rise rapidly to the surface, limiting oxygen transfer efficiency. The Aero-Tube® Ring Diffuser uses thousands of microscopic pores within the diffuser tubing to create an extremely fine mist of bubbles.
Microbubble Advantages
| Aeration Type | Oxygen Transfer Efficiency |
|---|---|
| Coarse Bubble Aeration | ★★☆☆☆ |
| Standard Air Stones | ★★★☆☆ |
| Aero-Tube® Microbubble Diffusion | ★★★★★ |
The result is:
✔ Higher dissolved oxygen levels
✔ Improved fish health and growth
✔ Better feed conversion ratios
✔ Reduced stress on aquatic stock
✔ Enhanced water circulation
✔ Lower energy consumption

How It Works
Compressed air is supplied through the diffuser inlet and distributed throughout the Aero-Tube® ring. Thousands of microscopic pores in the tubing wall release an ultra-fine cloud of oxygen-rich bubbles into the water.
Unlike conventional diffusers that produce large bubbles from a limited number of outlets, Aero-Tube® technology generates a continuous curtain of microbubbles along the entire length of the diffuser ring.
This creates:
- Greater oxygen transfer
- Improved water movement
- Better circulation patterns
- More stable dissolved oxygen levels
- Enhanced biological filtration performance
