Kasco Diffused Aeration
These highly efficient and effective diffused aeration systems are designed and sized to meet most typical aeration applications and come complete with everything you need including all connectors and adapter fittings.

MOVE & AERATE LARGE VOLUMES OF WATER
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

Kasco Home Series Diffused Aeration Systems are designed specifically for homeowners with small, residential ponds smaller than 2 acres with up to 20 ft. of depth. Using a shore-mounted compressor, air is continuously pumped through tubing lines that run to a single-loop diffuser on the pond bottom. The air is then released upward, creating non-stop water movement and mixing, which is vital in eliminating and preventing the most common water quality issues.
- 1 or 2 single-loop diffuser(s)
- 1/4 HP compressor (115V or 230V)
- Stainless steel ground-mount compressor cabinet
- SureSink weighted tubing
