Pricing
What does a nanobubble system cost?
No list price and no rounded estimate — the variables that set the number, and the inputs a quotation needs.
NanoMAR quotes each nanobubble system against its duty rather than publishing a price list, because the same machine costs very different amounts depending on what it is asked to do. A NanOxy Pro delivers 18.9 m³/h at 40 mg/L or 75.6 m³/h at 10 mg/L, and the gas supply built around it often weighs more heavily on the budget than the generator. Five variables set the price: delivered concentration, gas source, separation stage, installation route and duty cycle.
What drives the price
Ask what a nanobubble generator costs and the useful answer starts with three questions: at what concentration, into what water, running how many hours a day.
Delivered concentration is the dominant lever
A generator is bought against a delivered concentration, not a flow rate. The NanOxy Pro envelope makes the point: 18.9 m³/h at 40 mg/L, 37.8 m³/h at 20 mg/L, 75.6 m³/h at 10 mg/L. Same skid, three very different duty points. Fix the concentration first, then send every supplier the same duty point — our oxygen demand and sizing calculator gets you that figure.
The gas source is a second machine
Air costs nothing and needs no storage, but caps dissolved oxygen lower. Pure oxygen lifts that ceiling and is the only sensible feed at high stocking density or heavy organic load — with a generator, a tank or a supply contract behind it. Ozone adds generation and instrumentation.
The water decides the separation stage
Membrane, venturi and ceramic sit on one NanoMAR platform because no single method suits every water. Membrane wants clean feed and compressed gas; the NanOxy S1 module takes no electrical connection. Venturi tolerates dirtier water and moves the energy cost into the pump curve. Ceramic survives abrasive duty at a higher element price. Solids and temperature therefore price twice — equipment, then service interval.
Installation is the last lever: an existing pumped loop is cheap to tie into, a plant never designed for one is not.
Price indication by model
We publish specifications, not prices — but we can say where the money sits.
| Model | Flow | Where the cost sits | Bought by |
|---|---|---|---|
| NanOxy S1 | 0.3–1 000 m³/h | Scale itself — one membrane platform, bench rig to full industrial installation | Research groups, industry |
| NanOxy S2 | 2–50 lpm | Smallest entry point: portable, no site works, no tie-in | Laboratories, pilot preparation |
| NanOxy Pro | 18.9–75.6 m³/h | Concentration, gas supply, continuous-duty build; roughly 200 kg skid-mounted | Continuous aquaculture, RAS |
| NanOxy M Pro | 10–100 m³/h (nominal 35–55) | Flexibility — built to be moved and re-tuned, not fixed to one duty point | Process validation, scale-up |
| NanVANN Pro | 5–500 m³/h | Process breadth: TSS and TOC reduction plus TAN management | Wastewater treatment |
NanoMAR publishes neither prices nor delivery times; both are set per installation.
CAPEX vs OPEX
Capital cost is the visible half: generator, gas equipment, pump and pipework, instrumentation, installation, commissioning. Operating cost decides the comparison, and has fewer lines than buyers expect.
Electricity is the largest, and the pump usually dominates it rather than the generator. Gas comes next, and it scales with what you dissolve rather than what you inject — which is why transfer efficiency belongs in the commercial case, not only the technical annexe. Then consumables: elements, upstream filters, planned service.
One line is missing. Nothing is dosed, so there is no chemical spend, no chemical store and no residue to remove downstream. Ask every supplier for the same five categories: energy, gas, consumables, service, chemicals.
The figures a business case can rest on
The only performance figures NanoMAR publishes. Treat any supplier number without test conditions as marketing.
Energy cost per kg O2 transferred
Kilowatts are the wrong comparison. What sets the running cost is energy per kilogram of gas actually dissolved.
-
01
Measure what dissolves
Flow through the unit multiplied by the inlet-to-outlet difference in dissolved oxygen gives the mass transferred per hour. Gas lost at the water surface was bought and never used.
-
02
Count every motor in the loop
Feed pump, compressor and the oxygen plant if you have one — not the generator nameplate alone. The pump is usually the dominant load.
-
03
Divide, then compare like for like
Energy over mass transferred survives a supplier comparison. Ask for it at your temperature and water chemistry, not from a clean-water test.
-
04
Put bubble size in the result
Coarse bubbles rise, burst and take their gas with them. Bubbles under 200 nm stay suspended for days — which is why NanoMAR publishes 40 %+ higher oxygen transfer.
Typical payback period
We will not print a typical payback figure; a number invented for a brochure is worthless against your meter readings. Here is every line in the model.
- Gas purchased per month. Higher transfer efficiency means fewer kilograms bought for the same delivered concentration, every month the plant runs.
- Electricity for pumping and gas supply. Use the energy-per-kilogram figure at your own tariff, not nameplate power.
- Chemicals no longer dosed. Product, storage, handling, disposal. Nanobubble treatment doses nothing, so the line goes to zero.
- Cleaning, downtime and labour. Hours lost to biofilm, fouling and unplanned stops rarely appear in a supplier comparison.
- Solids and sludge handling. Suspended-matter removal of 80 %+ changes filter loading and disposal cost.
How our pricing compares
We will not publish another manufacturer's prices: we do not hold their quotations, prices here are set per project, and guesswork fails beside a real offer. If you want a Moleaer nanobubbles figure, ask them for it — then bring both offers back to one duty point.
What is worth comparing between nanobubble companies is narrow, and measurable. Energy per kilogram of gas transferred at your conditions. How many separation technologies the supplier offers, because a vendor with one method always recommends that method — NanoMAR runs membrane, venturi and ceramic on one platform. Whether the duty envelope covers your worst case. And whether anyone will pilot on your water first: any supplier worth shortlisting should agree to that.
Every duty envelope is published — see the specification for each nanobubble system, and the engineering behind it in how the generators work.

A water analysis
Solids, hardness and temperature range — this sets the separation stage and the service interval.
Site constraints
Existing pumps and pipework, available power and footprint, and whether compressed gas is on site.

Frequently asked questions
- How much does a nanobubble generator cost?
NanoMAR does not publish a nanobubble generator price, because one unit is specified at very different duties: a NanOxy Pro delivers 18.9 m³/h at 40 mg/L or 75.6 m³/h at 10 mg/L. Cost follows concentration, gas source, separation stage and duty cycle.
- Why does NanoMAR not publish a price list?
A list price would be wrong for almost every buyer. A NanoMAR nanobubble system spans 2 lpm on a laboratory bench to 1 000 m³/h on the NanOxy S1 membrane platform, and the gas equipment often moves the total more than the model does.
- What does a Moleaer nanobubble generator price look like?
NanoMAR cannot quote another manufacturer's equipment and will not estimate it. Ask Moleaer directly, then compare both offers at the same flow and delivered concentration, with energy per kilogram of gas transferred stated at your water conditions.
- Is a nanobubble system cheaper to run than chemical dosing?
The operating cost has a different shape. A NanoMAR nanobubble system adds only oxygen, air or ozone, so there is no chemical spend and no residue to remove — but electricity, gas and consumables remain.
- Can I buy a nanobubble generator outright?
Yes. NanoMAR sells its units outright across five models, from the portable NanOxy S2 to the NanVANN Pro wastewater platform. We would rather you pilot on your own water first, then specify the production unit from the measured result.
