Aeration systems utilize a shore-mounted air pump that delivers air to specialized diffusers that are located on the pond bottom. Resulting in a column of rising bubbles that circulates water throughout the pond, eliminating a change in temperature or thermocline. With increased oxygen and added natural bacteria, any excess nutrients in the pond or lake are metabolized, resulting in cleaner water and less muck. Results you can see in just 90 days!

Aeration circulates the water and increases oxygen, providing long-term benefits and reducing overall maintenance. Aeration is a key step in the Airmax Ecosystem, a simple 3 step approach to pond and lake management. The Airmax Ecosystem is the industry-leading method to achieve a clean, clear, thriving aquatic ecosystem. Learn more about the Airmax Ecosystem.

Easy Installation With Options

Airmax Aeration Systems are the easiest and most versatile systems to install on the market. PondSeries PS20 System can be installed at the water's edge or up to 1/4 mile away from the pond or lake. No power is needed at the shore, and select from 115V or 230V systems. Airmax EasySet airline delivers oxygen to the water without the added expense of hiring an electrician.

Airmax Composite Cabinet

ETL electrical safety certified composite cabinet has a quiet design with a faux rock finish to blend into any landscape. The removable top and side high-density air intake filter protect the compressor and pre-wired electrical box from outside contaminants while providing easy access. Other cabinet features include an elevated base protecting against damaging flood water and a ventilation fan with a rain shroud that cools and protects against moisture and heat damage. Cabinet dimensions: 23"L x 17"W x 15"H. Comes with a 10-year warranty.

SilentAir (IST) Compressor With SmartStart Technology

The heart and soul of each PondSeries Aeration System is a powerful whisper-quiet SilentAir 1/2 HP Rocking Piston Compressor built with SmartStart Technology (IST) to protect compressor during pressurized restarts following power supply interruptions. Each highly efficient 115V or 230V compressor has rubber mounts to reduce noise and vibrations and ensure a silent operation. Each compressor can push up to 4.7 CFMs of oxygen to your pond while costing as little as $33.00 a month. Comes with a 3-year warranty.

Airflow Manifold Assembly

Airmax simplifies airflow management to individual diffusers with a 2-port manifold with nickel-plated ball valves. Optional airline quick disconnects can be added for simplified removal during maintenance or for winter storage of systems that do not run year-round. PondSeries PS20 Systems is set up for 3/8" or 5/8" airlines.

ProAir 4 Weighted Diffusers

Designed for maximum oxygen uptake, 2 ProAir 4 Weighted Diffusers incorporate high-efficiency low-maintenance membrane sticks to release tiny oxygen bubbles into the water column. Membrane diffusers have the synergy of air stones without the headaches of cracking and acid-washing. The ProAir 4 Weighted Diffuser has an integrated check valve to prevent backpressure on the compressor. The innovative sled keeps the ProAir 4 submerged while maintaining an upright position during installation. Comes with a 5-year warranty.
