Providing bottom-diffused aeration in shallow ponds and lakes can provide a unique challenge to pond owners, as less water depth means smaller plate coverage, which usually translates to expensive, multi-plate systems. Shallow Water High Pressure Series™ Aeration Systems provide multiple plates to provide evenly distributed aeration in shallow water applications without forcing customers into large cost-prohibitive aeration units. Each system is made in the USA and is backed by a 2 Year Manufacturer’s Warranty.

The heart of the Shallow Water High Pressure Series™ Aeration System is the SilentAir™ Rocking Piston Compressor.  It 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. Each airline is equipped with Quick Disconnects for easy removal and storage. The entire compressor unit is protected by the Airmax® Composite Cabinet, which combines weather protection with a ventilation fan and high-density air intake filter to keep the compressor, cool, clean and dry. An elevated base protects hardware from flood or rainwater damage, and the cabinet is protected by a lifetime warranty (2 Year Warranty on electrical components).

Why Should you Aerate Your Pond?

  • Aeration is an efficient, inexpensive way to significantly expand circulation and dramatically increase dissolved oxygen levels
  • This results in increased beneficial bacteria colonization in your pond: reducing muck, improving water quality, and lowering maintenance!
  • Resulting higher oxygen levels make your fish more active and energetic, and can help prevent fish death during stressful conditions
