Airmax PondSeries PS20 Pond Aerator System

Aeration systems utilize a shore-mounted air pump that delivers air to specialized diffuser plates 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, clearer water and less muck. Results you can see in just 90 days!

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. Standard cabinet dimensions: 23"L x 17"W x 15"H

SilentAir™ Series Aeration Compressor
The heart and soul of each PondSeries Aeration System is a powerful whisper-quiet SilentAir 1/2 HP Rocking Piston Compressors built with SmartStart Technology to protect compressor during pressurized restarts following power supply interruptions. Each highly efficient 115V or 230V compressor comes with rubber mounts to reduce noise and vibrations to 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.

Optional ProAir™4 Weighted Diffuser
Designed for maximum oxygen uptake, the ProAir™4 Weighted Diffuser incorporates high-efficiency low-maintenance membrane sticks to release tiny oxygen bubbles into the water column. Membrane diffusers posses 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 back pressure on the compressor. The innovative sled design keeps the ProAir™4 submerged while maintaining an upright position during installation. Comes with a 5-year warranty.
