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

The Kasco Robust-Aire 2 120V Double Piston System offers reliable, high-efficiency pond aeration designed for larger or deeper ponds—without the added cost or bulk of a cabinet. This system features two long-lasting rocking piston compressors paired with Kasco’s signature Robust-Aire diffusers, ensuring optimal oxygen circulation across wide surface areas.

Engineered for long-term use and low maintenance, this setup is perfect for applications where a cabinet is unnecessary or where compressors will be housed in an existing structure. The oil-less, rocking piston compressors operate quietly and stay cool with minimal upkeep. Each diffuser is designed for maximum oxygen transfer and minimal clogging, even in murky or nutrient-rich water.

Whether you're managing a fish habitat, maintaining water clarity, or helping reduce unwanted algae and bottom muck, this aeration system is built to keep your pond balanced and productive year-round. With no electricity in the water and tubing designed to stay submerged, it’s also safer and easier to install compared to surface aeration systems.
