BUBBLE
NOZZLES
It's the bubble you want — not the box it comes in. Build longer-lasting oxygen reserves, eliminate pathogens, and control biofilms through your existing pump, gas supply, and pipework.
It's Just the Nozzle
This is not a nanobubble generator. No box, no control panel, no internal compressor — because the nozzle is the part that makes the nanobubbles. Everything else you either already have, or can source for far less.
Run the Pump You Already Own
The nozzle doesn't care where the flow comes from. Your existing pump, your circulation loop, your centralised system — if it moves water, it makes nanobubbles. Need a pump? We size them for a living — flow, pressure, friction losses, the lot.
Bleed Off Your Own Gas
Already running oxygen or ozone on site? Just tee off what you need — no duplicate gas source, no standalone unit. No gas supply yet? We supply generators and concentrators separately, sized to your system.
Skip the Box, Keep the CapEx
A nanobubble generator is a nozzle in a nice little box — with a price tag to match. 90% of the time, farmers already have almost everything they need. Why buy componentry you already own, locked inside an inflexible unit?
It's the bubble you want — not the box it comes in.
Everything you need, nothing you don't. Maximise your effectiveness, minimise your capital expenditure, and build on the equipment you already own — or industrial gear you can source for far less.
Why Professionals Choose Nanobubbles
Nanobubbles are tiny, stable bubbles that do big things for your aquaculture system. Here's what sets them apart.
Resistant to Degassing
Build longer-lasting oxygen reserves in water. Nanobubbles remain suspended far longer than conventional bubbles, ensuring sustained gas transfer.
Additional Biosecurity
Helps eliminate harmful bacteria, viruses, and parasites for healthier stock and cleaner water without chemical additives.
Increased Oxidation Capacity
Breaks down waste and organic materials more effectively than conventional aeration methods for cleaner system water.
Real Nanobubble Numbers
Bubble size stays locked in the true nanobubble band while concentration climbs the longer water circulates through the nozzle. After 40 minutes of circulation, every millilitre of water carries 42 million bubbles.
| Circulation Time | Bubble Size | Concentration (Bubbles/ml) |
|---|---|---|
| 5 mins | 151 nm | 5,800,000 |
| 10 mins | 146 nm | 10,900,000 |
| 40 mins | 193 nm | 42,000,000 |
Bubble concentration measured in bubbles per millilitre of water. Circulation time = total time water is recirculated through the NBN nozzle.
🔬 True Nanobubble Scale
146–193 nm bubble diameter across all circulation times — hundreds of times smaller than a human hair, squarely in the nanobubble range where stability and gas transfer peak.
📈 Concentration Builds
5.8 million after 5 minutes, 42 million after 40. Because nanobubbles resist degassing and stay suspended, every pass through the nozzle stacks more bubbles into the same water.
🫧 Consistent Size, Rising Density
The nozzle keeps producing the same tiny bubbles run after run — what grows is concentration, not bubble size. That means predictable oxygen reserves and sustained gas transfer.
Engineered for Performance
Every NBN nozzle delivers a suite of benefits that transform your water treatment capabilities.
💨 Resistant to Degassing
Build longer-lasting oxygen reserves in water. Nanobubbles remain suspended far longer than conventional bubbles.
🛡 Additional Biosecurity
Helps eliminate harmful bacteria, viruses, and parasites for healthier stock and cleaner water.
⚡ Increased Oxidation
Breaks down waste and organic materials more effectively than conventional aeration methods.
💳 Reduced O&O Use
Lower oxygen and ozone consumption is a typical outcome of nanobubble application in aquaculture.
🌱 Controls Biofilms
Reduces buildup in pipes and tanks, improving water quality and overall system efficiency.
🌀 Brownian Motion Mixing
Nanobubbles exhibit continuous random motion (Brownian motion), keeping them dispersed throughout the entire water column. In large volumes, this means more uniform oxygen distribution — even in deep tanks and far corners where conventional bubbles never reach.
⚗ Hydroxyl Radicals & ORP
Nanobubbles spontaneously produce hydroxyl radicals (•OH) when they collapse — one of nature's most powerful oxidisers. This drives a measurable increase in ORP (Oxidation-Reduction Potential), enhancing your system's ability to break down organic waste and suppress pathogens without additional chemical dosing.
💰 Cost Effective
Low upfront investment. No expensive hardware — our nozzles work with equipment you already have.

Supercharge Your Nanobubbles
Nanobubble nozzles work with ambient air, but the real magic happens when you feed them concentrated oxygen or ozone. Supercharge your gas transfer and unlock the full potential of nanobubble technology.
Ozone Generators
Feed ozone into your nanobubble nozzle for maximum oxidation and pathogen control. Our Redox Air and V-Series ozone generators pair perfectly with NBN nozzles. View Ozone Range →
Oxygen Concentrators
Feed high-purity oxygen into your nanobubble nozzle and watch dissolved oxygen levels climb faster and hold longer than any conventional method. The Oxisat range delivers reliable concentrated oxygen on demand. View Oxisat Range →
The Combined Effect
Oxygen + Ozone + Nanobubbles = the ultimate water treatment stack. Nanobubbles dramatically increase gas transfer efficiency, meaning less gas consumed, better results, and a system that's cleaner, safer, and more energy-efficient.

Stop Overpressurising Your Oxygen Cone
Do you run an oxygen cone with a venturi? There's a much better way to dissolve gas.
The Venturi Bottleneck
You're wasting energy forcing coarse bubbles into solution. When introducing gas via a contact nozzle (venturi), you need initial pressure to overcome the downward force of the cone. But it doesn't stop there. You then need to maintain high secondary pressure inside the reactor just to force those coarse bubbles into solution.
The Solution: Shrink Your Bubbles
Shrink your bubbles. Shrink your pressure. By breaking the gas down into nanobubbles, transfer happens almost instantly. Because there is far less loose oxygen left fighting to be dissolved, you don't have to run as high of a pressure in the reactor to get the job done.
Energy Savings
By lowering the secondary pressure requirement in the oxygen cone, you significantly decrease your pump's power use. Smaller bubbles = less pressure needed = less energy consumed. It's that simple.
Superior Immediate Transfer
The surface-area-to-volume ratio of nanobubbles means dissolution happens far quicker than venturi-produced bubbles. More gas transferred, less gas wasted.
Nitrogen Stripping
The tiny footprint of oxygen nanobubbles more effectively strips dissolved nitrogen gas from your water column — critical for fish health in intensive systems.
The Nanobubble Edge
You get all the inherent benefits of nanobubble technology — highly resistant to degassing, higher redox potential, and pathogen control. This isn't just a cone upgrade — it's a system transformation.
