Kasco Robust-Aire Aeration System


Robust-Aire systems are quiet, move the most water, and provide great aeration benefits for applications 8 ft. or deeper. By pumping compressed air from a shore-mounted compressor, air is pushed through self-weighted lines to a diffuser on the pond, lake or tank bottom. The diffuser then continuously releases micro-bubbles that rise to the surface carrying large volumes of water. This induces oxygen-transfer as well as beneficial water movement and mixing. Kasco’s Robust-Aire has been independently tested to be up to 44% more efficient than any other system, meaning you can use less energy, spend less money, and get better results.

  • Packages include diffuser assembly, compressor, and compressor mounting option
  • The stainless steel diffuser assembly includes built-in strain relief and lands right side up every time
  • Large air filters allow for less frequent maintenance
  • Visual maintenance indicators quickly alerts when air filters need attention
  • Eliminates thermal and chemical stratification 
  • No electricity in the water 
  • Creates open water to prevent ice damage to docks and boats 

Multiple Mounting Options: Base Mount Cabinet, Post Mount Cabinet, or No Cabinet
