Is your pond turning murky, stagnant, or full of unwanted scum? Still water builds up bacteria and starves fish of oxygen, leaving your pond looking neglected and unhealthy. This ½ horsepower electric aeration system pushes life-giving oxygen through your entire water column, treating ponds and lakes up to 2 surface acres. Set it, walk away, and let clean, clear water take care of itself.

Oxygen is the single most important thing your pond needs. A well-oxygenated body of water keeps fish and aquatic life healthier and living longer, while circulation stops the stagnation that breeds bacteria and scum.
At the heart of the system sits a single ½ horsepower compressor that pushes up to 5.3 cubic feet of air per minute down to the diffusers. That steady stream of air lifts water from the bottom to the surface, mixing the whole column and eliminating stratification.
The Duraplate™ diffusers are the workhorses that release air into your water. They are non-clogging and self-cleaning, so you spend less time on maintenance and more time enjoying a clear pond.
Diffuser options: The cabinet-only variants ship without diffusers, while the 1.2 configurations include 2 Duraplate diffusers.
This is the only aeration system on the market that comes with a programmable timer, putting you in full control of exactly when your water gets aerated. The UL Listed timer gives you real flexibility over your run schedule and your electric bill.
Inside the cabinet you will also find a 4-port brushed aluminum manifold for easy expansion, a pressure gauge, a high volume cooling fan, and fully adjustable controls, all wrapped in a durable, sound-deadening cabinet with a rugged ¾ inch thick construction running at just 50/60 DB.
Got a remote pond or awkward electrical access? No problem. The cabinet installs away from the water's edge, wherever your electrical hook-ups are most convenient.
This makes the system a strong fit for HOAs, golf courses, retention ponds, farm ponds, aquaculture ponds, ski parks, zoological displays, and recreational lakes.
Electric aeration is one of the cleanest ways to care for your water. It is a completely green option that requires very little maintenance while running around the clock.
Voltage options: Choose from 115V or 230V compressor configurations across the range.

What you get depends on the configuration you choose, so you only pay for what your project needs.
Every 1.2 system includes a single compressor, programmable timer, 4-port manifold, pressure gauge, and cooling fan housed in the sound-deadening cabinet.
