Airmax PondSeries PS20 Pond Aerator System

Introducing the Airmax PondSeries PS20 Pond Aerator System, a top-of-the-line solution for maintaining the health and clarity of your pond. This revolutionary system uses shore-mounted air pumps to send air to specially designed diffuser plates at the bottom of your pond.

The resultant rising column of bubbles circulates water throughout the pond, eradicating temperature differences or thermoclines.

With a boost in oxygen levels and the addition of natural bacteria, your pond's excess nutrients are efficiently metabolized, yielding cleaner, clearer water with less muck. Experience visible differences in just 90 days!

Premium Airmax® Composite Cabinet
Our Airmax® Composite Cabinet, ETL-certified for electrical safety, boasts a silent design with a faux rock finish that seamlessly blends into any landscape. The high-density air intake filter on the removable top and side safeguards the compressor and pre-wired electrical box from exterior contaminants, while also facilitating easy access.

Airmax Composite Cabinet

The cabinet's other features like the raised base guard against potential flood damage. A ventilation fan, complete with a rain hood, provides cooling and protection against moisture and heat damage. The standard cabinet measures 23"L x 17" W x 15"H.

Efficient SilentAir™ Series Aeration Compressor
Each PondSeries PS20 Pond Aerator System is powered by a robust, near-silent SilentAir 1/2 HP Rocking Piston Compressor. The SmartStart Technology safeguards the compressor during high-pressure restarts after power interruptions.

These highly efficient compressors operate at 115V or 230V, include rubber mounts that reduce noise and vibrations and can deliver up to 4.7 CFMs of oxygen to your pond. Moreover, they cost as little as $33.00 per month!

ProAir™4 Weighted Diffuser (Optional)
For optimal oxygen uptake, consider the optional Airmax ProAir™4 Weighted Diffuser. This component, engineered for high efficiency and low maintenance, uses membrane sticks to release minuscule oxygen bubbles into the water column.

Airmax Weighted Diffuser

Experience the advantages of air stones without the issues of cracking and acid-washing. The ProAir™4 has a built-in check valve that resists back pressure on the compressor and an innovative sled design that keeps it submerged and upright during installation. This diffuser comes with a five-year warranty.

EasySet™ Weighted Airline (Optional)
Resilient against rips, tears, fishing hooks, and foot traffic, the optional EasySet™ airline promises the ideal safety for your pond.

Airmax EasySet Airline

Its thick, lead-free construction and the 3/8” Weighted Airline are designed to stay submerged underwater and out of sight, with a guarantee that they will not float.
