Airmax
Best Aeration in the World
Aerators play a vital role in maintaining sufficient oxygen levels and supporting a balanced sanitary ecosystem. A properly sized lift station aeration system helps prevent stratification, reduce oxygen depletion, and limit harmful gas buildup.

Tech Specs







This isn’t new technology and it’s not particularly unique. There are lots of mechanical aerators used with varying degrees of success in municipal lift stations. That’s a fancy way of saying they “kinda” work.
Full transparency – the Airmax product was never designed nor intended for use in a municipal lift station. It’s actually designed for use in ponds.
So, where’s the “Big Why”, then?
All mechanical aerators, help, however, their effect wears off quickly in municipal sewers, and when it comes to FOG, in the absence of any other technology, effectively emulsify the FOG and simply send the problem downstream.
Airmax, which provides incredibly great “bang for your buck”, would do the same – if it was the only technology in play. It just happens to work in a way that makes it easy to use in lift stations, is highly effective in raising DO (dissolved oxygen) in effluent streams, is easy to install and easy to maintain.
However, when Airmax is teamed up with a proper Eganix biological treatment program, which often includes pairing
a chemical treatment program using calcium nitrate or ferrous chloride provided by others, all of a sudden, 1+1+1 = 10!!
No effluent stream is the same – so, no solution can be the same.
