Robust-Aire 2 Pond Aerator – 240V System Without Cabinet

The Robust-Aire 2 240V System (No Cabinet) is a dependable, direct-to-the-point solution for maintaining healthy water in medium to large ponds. Designed for performance and quiet operation, this system is perfect for those who already have an equipment enclosure or prefer to install the compressor in a protected area of their choosing.

Running on a 240-volt electrical setup, the Robust-Aire 2 includes a high-efficiency rocking piston compressor and two self-weighted diffuser assemblies. These diffuser bases sit securely on the pond bottom, producing fine air bubbles that naturally lift water from the bottom up, circulating oxygen throughout the entire water column. This helps reduce sludge buildup, limit algae growth, and support aquatic life.

Because this version ships without a cabinet, it offers cost savings and flexibility—great for installations where a cabinet isn’t needed or where a custom setup is planned. All components are made to last, with corrosion-resistant fittings and heavy-duty airline connections to withstand demanding environments year-round.

Whether managing a fish pond, stormwater basin, or a backyard water feature, this aeration system delivers long-term reliability and consistent results.
