Providing bottom-diffused aeration in shallow ponds and lakes 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 Series Aeration Systems provide multiple plates to provide evenly distributed aeration in shallow water applications without forcing customers into large cost-prohibitive aeration units. Designed specifically for use in shallow water, our Shallow Water Series Aeration Systems aerate ponds up to 1/2 surface acre at 6 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.
