Airmax SW20 Shallow Water Series Pond Aerator System

Crafted specifically for shallow water applications, the SW20 Shallow Water Series Pond Aerator by Airmax efficiently oxygenates up to 1/4 acre of the pond up to 6’ deep.

Unlike traditional systems that typically require larger, cost-prohibitive multi-plate setups for such applications, this aerator system ingeniously uses multiple plates for even distribution of aeration.

Robust Airmax® Composite Cabinet
Hosting the SilentAir™ Compressor, the Airmax® Composite Cabinet shields vital hardware against the elements. This unit boasts an advanced cooling system featuring a ventilating fan with rain shroud and a high-density air intake pre-filter, ensuring all internal components stay clean, dry, and cool.

Airmax Composite Cabinet

Notably, its raised base defends against flooding and excessive rainwater. The removable top enables hassle-free inspections and necessary upkeep. Pre-wired electrical box and a 6-foot power cord come alongside the ETL-listed cabinet.

Lastly, the Airmax® Composite Cabinet offers a lifetime warranty on the cabinet itself and a 2-year warranty on all electrical components.

Efficient SilentAir™ LR Series Linear Diaphragm Compressor
The SilentAir™ LR Series Linear Diaphragm Compressor, the core of every Shallow Water Series™ Aeration System, combines power with energy efficiency.

Besides providing huge quantities of oxygen, it maintains a hushed operation. This compressor features an integrated Manifold with Ball Valves for efficient airflow management and comes mounted on rubber feet to minimize vibrations and noise.

For added convenience, each airline includes Quick Disconnects for streamline system removal and storage.

ProAir™2 Weighted Diffuser
The ProAir™2 Weighted Diffuser ensures maximum oxygen diffusion without the typical drawbacks of traditional air stones, such as cracking or the need for acid-washing.

Airmax Shallow Water Weighted Diffuser

It releases minuscule oxygen bubbles into the water column using easy-to-maintain membrane sticks.

The integrated check valve safeguards the compressor against back pressure. Its innovative sled design keeps the diffuser submerged while facilitating upright installation. This unit comes with a 5-year warranty.

Durable EasySet™ Airline
The EasySet™ Airline, with its thick wall and lead-free construction, is designed to provide longevity and pond safety. Its tough structure resists damage from fishing hooks, foot traffic, and contact with pets or wildlife.

Airmax EasySet Airline

The 3/8" weighted airline is engineered to stay submerged and hidden from view, and it also guarantees not to float.
