These aerators provide natural-looking aeration by pumping air from the floor of your water body.
sub-surface aeration
Highlights
01
Lower set up cost Surface aerators are typically lower cost for the equipment than surface aerators
02
Lower power consumption Sub-surface aerators typically use less power to run than surface aerators
03
Suitable for swimming dams Because there is no power in the water, sub-surface aerators are suitable for swimming dams
04
Best for deep water The best option for water deeper than 5m
Choose from the following sub-surface aerators
Hakko
Matala
Vertex
OWS Windmill
Remote setup available
Have mains power within 200m of your waterbody? It's worth noting Matala and Vertex aeration systems can be installed in a remote setup where a mains-powered motor is positioned near the AC outlet and air is pump through hose buried in a shallow trench.

Solar conversions available for Matala and Vertex kits.
We can make any Matala or Vertex aeration kit solar powered by adding our USA manufactured solar drive, purpose-built for these types of compressors. The drive connects directly to your solar panels and incorporates an inverter, VFD, MPPT controller, phase initiator and voltage booster. Visit the Matala or Vertex aerator pages for more info.

How does sub-surface aeration work?
expert tip
Have a deep dam? Combine surface and sub-surface aerators for premium results.
If you have a deep dam, and you want the cleanest water possible, combine aerators to get the benefits of both. Surface aerators are better at aerating the top layers of water and sub-surface aerators are better at bringing bottom waters to the surface. The result is a much more mixed and aerated waterbody. We also have the option of mixing and matching sub-surface equipment, e.g. using a Vertex compressor with Matala in-water components. This offers you the best combo of price and quality, e.g. using higher quality electrical components with lower cost static components.

FAQs: Answers from Scotty Tucker
Sub-surface aerators use less power than surface aerators because the motors only have to move air while surface aerators move water. A typical sub-surface aerator will use about as much energy as a household fridge.
Our sub-surface aerator kits start at around $1,999 for the complete kit, i.e. everything you need to get set up. This would be for the Hakko aerator.
Really we encourage you to complete a Dam Diagnostics Survey and let us recommend a size. The reason is many things impact motor size, including depth, dam shape, islands, temperature, microbiology etc. With ideal conditions though, the calculation is roughly...
Dams <2.5m: ½ hp aerates ¾ acres
Dams 2.5-3.5m: ½ hp aerates 1.5 acres
Dams >3.5m: ½ hp aerates 3 acres

Yes, we do. This is typically for customers close to Melbourne but we do travel for project work. We may also be able to refer you to a local installer, if we know of one in your area. Please reference this in your enquiry and we can provide an idea of the cost. We also have installation videos for those who want to go it alone.
