Providing bottom-diffused aeration in shallow ponds and lakes with low maintenance aeration systems can provide a unique challenge to pond owners. Less water depth means smaller plate coverage which usually translates to bigger, more expensive, multi-plate systems. Our Shallow Water HP Series™ Aeration Systems provide multiple plates to provide evenly distributed aeration in shallow water applications without forcing customers into large cost-prohibitive aeration units. Our high pressure system built with SilentAir™ rocking piston compressor last longer compared to other diaphragm compressors on the market today. Designed specifically for ponds and lakes up to 1/2 surface acre at 10’ deep.

Airmax® Composite Cabinet

Our attractive composite cabinet houses and protects the SilentAir™ Compressor from outdoor elements. An integrated cooling system utilizes a ventilation fan with rain shroud and high-density air intake pre-filter to distribute air evenly throughout the cabinet keeping the interior components clean, cool and dry. An elevated base protects the aeration hardware and electrical components from flooding and rainwater accumulation while the removable top ensures quick and easy access for inspection and maintenance. Every Airmax® Composite Cabinet in our Shallow Water Series™ comes complete with a pre-wired electrical box and 6 foot power cord to provide power to the enclosed cooling fan and aeration compressor. The Airmax® Composite Cabinet comes with a lifetime warranty on the cabinet and a 2-year warranty on electrical components.

SilentAir™ Series Aeration Compressor

The heart and soul of each Shallow Water HP Series™ Aeration System, our powerful whisper-quiet SilentAir™ rocking piston compressors built with SmartStart™ Technology to protect the compressor during pressurized restarts following power supply interruptions. Each compressor pushes oxygen through your pond while remaining energy efficient – costing as little as $9.27 a month in electricity running 24/7. Each SilentAir™ aeration compressor is fitted with an integrated air regulator to provide easy airflow-management and is mounted on vibration reducing rubber feet to ensure quiet operation.

ProAir™2 Weighted Diffuser

Designed for maximum oxygen uptake, our ProAir™2 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™2 Weighted Diffuser has an integrated check valve to prevent back pressure on the compressor. The innovative sled design keeps the ProAir™2 submerged while maintaining an upright position during installation. Comes with a a 5-year warranty.

Recommended usage can be year round. Summer to provide water movement, bind phosphates to the bottom of the pond, oxygen to the bottom of the pond for more fish capacity, take away their stress, prevent fish kills and promote beneficial pond bacteria (aerobic bacteria ) to the bottom of the pond to reduce muck and nutrients.

Winter use is to keep a hole in the ice for off gassing of toxic gasses. Keep the pond breathing so the fish don’t suffocate under the ice.
