High-Efficiency Aeration Pump

Running on 35 watts, the whisper-quiet SilentAir™ aeration pumps are the heart and soul of our KoiAir™ aeration units. Costing little to run, you can feel good about providing constant aeration to your pond.

EasySet™ Weighted Airline

Our heavy-duty flexible airline is designed to sink the pond’s bottom even when filled with air. EasySet™ airline is extremely resistant to cuts, snags, and kinks for maximum performance with minimal headaches.

Diffuser Plate Assembly

Each KoiAir™ diffuser plate utilizes a sturdy base plate and incorporates a 3/8” barbed inlet for quick hook-up to the included EasySet™ airline while providing threaded female outlets to accommodate membrane diffuser sticks.

Membrane Stick Diffusers

Designed to improve oxygen absorption, our diffuser membrane delivers all of the performance of air stone diffusers without the hassles of replacing cracked stones or frequent cleanings due to debris accumulations. Virtually maintenance-free, the membrane diffuser stick resists clogging and their flexibility eliminates the possibilities of cracking and leaking.

Protect Your KoiAir™

In order to stay out in the elements, Airmax® recommends covering the KoiAir™ 2 with a Small TrueRock™ Boulder Cover (sold separately).
