  • Airmax SW40 Shallow Water Pond Aerator System

    The Airmax® Shallow Water Series™ Pond Aerator System utilizes multiple plates to provide evenly distributed aeration in shallow water applications without forcing pond owners into large cost-prohibitive aeration units.

    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. Designed specifically for use in shallow water, the Shallow Water Series™ SW40 Pond Aerator System aerates a pond up to 1/2 surface acre at 6’ deep. 

    Airmax® Composite Cabinet
    The Airmax® 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 comes complete with a pre-wired electrical box and 6 foot power cord to provide power to the enclosed cooling fan and aeration compressor and is ETL Listed. The Airmax® Composite Cabinet comes with a lifetime warranty on the cabinet and a 2-year warranty on electrical components.
