Providing bottom-diffused aeration in shallow ponds and lakes can provide a unique challenge to pond owners. The Airmax® Shallow Water High Pressure Series™ Aeration Systems provide multiple plates to provide evenly distributed aeration in shallow water applications without forcing customers into large cost-prohibitive aeration units! Aerates ponds up to 1/4 surface acre at 6' deep. Made in the USA.

SilentAir™ Rocking Piston Compressor with Composite Cabinet
The heart of the Shallow Water High Pressure Series™ Aeration System is the SilentAir™ Rocking Piston Compressor, which works effectively while costing as little as $9.27/month. Integrated Manifold with Ball Valves simplifies airflow-management and vibration-reducing rubber feet ensure quiet operation. Each airline is equipped with Quick Disconnects for easy removal and storage. The entire compressor unit is protected by the Airmax® Composite Cabinet, which combines weather protection with a ventilation fan and a high-density air intake filter to keep the compressor cool and dry. Includes a pre-wired electrical box and 6' power cord. An elevated base protects hardware from flood or rainwater damage. Cabinet is protected by a lifetime warranty, while compressor and electrical components have 2 year warranty.

EasySet™ Airline and ProAir™ 2 Diffuser
Air is delivered by EasySet™ Airline (Not included), which is resistant to rips and tears and is weighted in order to stay submerged and out of sight, to the virtually maintenance-free ProAir™-2 Weighted Diffuser, which have an innovative sled design that remains submerged while maintaining an upright position. The high-efficiency, low-maintenance membrane sticks release air into the water column with the efficacy of airstones -- without all the maintenance! Each diffuser also has an integrated check valve to protect the compressor from back-pressure. Diffusers backed by 5-year warranty.

Why Should you Aerate Your Pond?

  • Aeration is an efficient, inexpensive way to significantly expand circulation and dramatically increase dissolved oxygen levels
  • This results in increased beneficial bacteria colonization in your pond: reducing muck, improving water quality, and lowering maintenance!
  • Resulting higher oxygen levels make your fish more active and energetic, and can help prevent fish death during stressful conditions
