Know before you buy
The system uses a shore-mounted compressor to pump air through weighted tubing to diffusers placed on the pond floor. These diffusers release fine bubbles that rise to the surface, creating a current that circulates and oxygenates the entire water column without needing electrical components in the water.
Yes, the system supports an optional remote manifold that allows you to place the compressor up to one mile away from the water's edge. This is ideal if you need to keep the equipment near a power source or hidden away from the shoreline for aesthetic reasons.
Yes, this system is effective for winter deicing applications. The constant movement of water from the bottom to the surface prevents ice from forming around the diffuser area, which also helps maintain oxygen levels for fish during the colder months.
The Robust-Aire system is designed to operate at depths of up to 50 feet. It is important to match the system configuration to your specific pond depth and acreage to ensure optimal oxygenation.
The rocking-piston compressors are built for continuous, low-maintenance operation. Aside from routine checks and occasional filter cleaning, the system is designed to run reliably for long periods without frequent intervention.
The choice depends primarily on your pond's surface acreage and depth. The RA1 and RA3 are generally rated for up to 1.5 surface acres, while the RA2 is designed to support up to 3 surface acres; you should select the model that best aligns with your specific pond size and oxygenation requirements.
