Robust-Aire 3 120V No Cabinet – Pond Aeration Power Without the Cabinet

The Kasco Robust-Aire 3 system is a reliable and efficient aeration solution for ponds and lakes up to 12 acres in size. Designed for users who already have a cabinet or wish to house the compressor in a structure of their choice, this version of the Robust-Aire 3 comes without a cabinet, giving you flexibility and control over your installation.

This 120V system includes a powerful rocking piston compressor, three durable diffusers, and 300 feet of 3/8" weighted airline. The diffusers sit at the bottom of your pond or lakebed, continuously moving water to improve oxygen levels, circulation, and overall water health—helping to reduce muck, control odors, and support aquatic life.

The compressor operates quietly and efficiently, making it a low-maintenance option for year-round use. All components are built to withstand demanding environments and long-term use. This system is also a great fit for retrofitting or replacing older systems while maintaining high performance.
