Robust-Aire 2 Aeration System – 120V Double Piston, No Cabinet

The Robust-Aire 2 120V system with no cabinet and a powerful double piston compressor is built to handle demanding pond aeration needs. Designed for larger or deeper ponds, this system efficiently circulates water from bottom to top, helping to support water clarity, improve oxygen levels, and support aquatic life. With two diffuser assemblies and self-weighted airline included, it’s ideal for installations where a cabinet is not necessary—such as when mounting in an existing shed, building, or structure.

Engineered for maximum airflow and low energy use, this system features a quiet, oil-free double piston compressor that delivers consistent performance even in ponds up to 50 feet deep. The self-cleaning diffusers release micro-bubbles that rise rapidly, improving gas exchange and water quality. Constructed from high-quality materials, the system is built for long-term durability in various pond environments.

Whether you're managing a recreational pond, fish habitat, or small lake, the Robust-Aire 2 delivers reliable performance without the noise or high maintenance of surface aerators. By placing diffusers at the bottom of your pond, this system helps to keep your entire water body active and fresh.
