Ultra-fine bubbles, far higher OTE
Tiny bubbles have more surface area and rise far more slowly than coarse bubbles, staying in contact with the water much longer — much more oxygen per unit of air than air stones or perforated pipe.
Oxygen supply diffuse nano pipes for Biofloc fish farm
Tiny bubbles, maximum oxygen transfer — a flexible nano bubble aeration tube that releases ultra-fine bubbles across the tank bottom, dramatically raising oxygen-transfer efficiency for biofloc, RAS and intensive ponds, while its small bubbles also keep the floc suspended; rugged, self-cleaning EPDM membrane construction connects straight to any roots or regenerative blower.

Oxygen supply diffuse nano pipes for Biofloc fish farm
Reduced power cost
Benefits of Nano-Tube/aerotube/air hose technology include reduced energy costs, higher ratio of oxygen / kWh transfer due to fine bubbles. Because low air resistance combines with thousands of tiny pores on the tube, power consumption is low, performance of oxygen transfer is effective.
Efficient dissolved oxygen
Dissolved oxygen level is higher and oxygen in pond bottom is markedly improved because Nano-Tube transfers oxygen in the water quickly and effectively. It is the top choice for aquaculture farms with high density in order to improve the quality of water environment today.
Advantages
Reduce energy costs up to 75%
No moving parts, low depreciation
Maintain the level of dissolved oxygen is higher
Initial investment cost is low
More productive
Allowing higher density
Allow to eat more often
Faster growth and reduced FCR
Simple installation, low maintenance
Nano-Tube creates important breakthrough in

| Form | Flexible micro-pore aeration hose — by the metre, or pre-assembled diffuser grids / rings / coils |
|---|---|
| Membrane | EPDM / rubber micro-pore membrane — flexes with each air pulse so pores self-clean |
| Bubble size | Micro / nano ultra-fine bubbles for high oxygen-transfer efficiency (OTE) |
| Common diameters | Ø ~12 / 16 / 20 mm (by series) |
| Air source | Roots blower / regenerative (ring) blower |
| Layout | Sized by metres of tube per m² of tank bottom plus matching blower air volume |
| Water type | Freshwater / seawater (corrosion-resistant membrane and fittings) |
| Options | Weights, connectors / air manifolds, stainless brackets, complete diffuser grids |
System composition
Double duty in biofloc
Oxygenates the dense biomass and gently keeps floc particles suspended and circulating — the standard diffuser for biofloc systems.
Self-cleaning EPDM membrane
The membrane flexes slightly with each pulse of air so the pores open and clear themselves, resisting clogging in biologically active water.
Connects to any blower
Standard fittings link straight to roots or regenerative blower manifolds.
Flexible configuration
Supplied by the metre or as pre-assembled grids and rings, in freshwater and seawater grades, laid out to your tank-bottom area.
Efficient at depth
Bottom-laid micro-pore diffusion keeps dissolved oxygen uniform even in deep tanks and ponds.
Application
- Biofloc farming — the core consumable for bottom aeration and floc suspension
- Bottom aeration of RAS sumps and deep intensive ponds
- Uniform oxygen supply in hatchery and larval-rearing tanks
- Bottom aeration of lined shrimp ponds and high-density fish ponds
- Fine-bubble diffusion in wastewater aeration basins (cross-industry duty)
FAQ
Frequently asked questions
How does a nano aeration tube improve oxygen transfer?
Fed by a Roots or regenerative blower, the tube’s micro-porous membrane releases huge numbers of ultra-fine micro/nano bubbles. Because tiny bubbles have far more surface area and rise more slowly, they stay in contact with the water longer, giving much higher oxygen-transfer efficiency than air stones or perforated pipe.
Why are nano tubes the standard diffuser for biofloc?
In biofloc systems they do double duty — they oxygenate the dense biomass and gently keep the floc particles suspended and circulating.
Does the nano tube clog in biologically active water?
The flexible EPDM / rubber membrane flexes slightly with each pulse of air, so the pores open and self-clean, resisting clogging.
What blower do I need for the nano aeration tube?
It connects straight to any standard Roots or regenerative blower manifold; selection is by tube length and pore rating versus blower air volume and water depth.
