Robust-Aire 3 240V No Cabinet RM – Reliable Pond Aeration Without the Housing

When it comes to consistent, energy-efficient pond aeration, the Robust-Aire 3 240V system without a cabinet is built for performance. Designed for large ponds and lakes, this system includes a powerful 3/4 HP rocking piston compressor and three diffuser stations, engineered to provide high oxygen transfer and bottom-to-top circulation for ponds up to 12 acres.

This version comes without an equipment cabinet, offering more flexibility for custom installations. It's a great fit for users who already have housing in place or plan to mount the compressor in a shed or structure of their own. The compressor runs quietly and efficiently, minimizing disruption while working hard to improve water clarity, reduce muck, and support fish health.

Each diffuser station includes a self-weighted base and durable rubber membrane diffusers that produce ultra-fine bubbles. These bubbles increase dissolved oxygen levels while maintaining low back pressure for system longevity. With weighted airline options available (sold separately), this setup is ready to work in deep and shallow waters alike.
