Stagnant water turns a beautiful pond into a problem fast. Low oxygen invites bacteria, scum, and fish kills, leaving your water murky and uninviting. This system pushes fresh air through your entire water column, day and night, so your fish stay healthy and your water stays clear. Built to run 24/7 and tough enough to last for years, it treats ponds and lakes up to 14 surface acres without a fuss.
At the heart of this system sit four custom-built ½ horsepower compressors, each capable of delivering 5.3 cubic feet of air per minute for a combined output of up to 21.2 cubic feet of air per minute. That air travels down to the bottom and rises through every layer of your pond, breaking up stagnant zones where trouble starts.
Choose the voltage that fits your site: this system comes in 115V or 230V.
The Duraplate diffusers are where the air meets your water, and they are built to take a beating. Each one is self-cleaning and non-clogging, with shrouded parts that keep debris and predators away from the working components.
Package options: pick the Cabinet Only configuration, or the version that includes 14 Duraplate diffusers ready to drop in.

Open the cabinet and you will see why this system holds up. Everything is packed into a durable, sound-deadening housing that measures 40"W x 24"L x 24"T and runs at a quiet 50/60 DB.
This is the only aeration system on the market that offers a programmable timer, and you can add it on if you want full control over your run schedule. Add it or skip it: choose No Timer or With Programmable Timer.
The UL Listed timer puts you in charge:
Choosing when to run helps cut electric costs and save energy while keeping your water in shape.
Electrical hookups are rarely right at the water's edge, and this system is designed around that reality. You can set the cabinet where power is convenient and still aerate a pond far away.
This system is engineered to outlast cheaper setups at every point that matters. The custom-built compressors, heavy cabinet, and protected diffusers all work together for reliable, problem-free operation season after season.
