Verified by independent testing‚ these systems are the most efficient on the market! Third-party testing has rated them up to 44% more efficient than competing models. These diffusers provide a fine air bubble‚ destratifying your pond to prevent seasonal turnovers and create uniform temperature and oxygen levels throughout your water column.

Systems include everything you need to start aerating. They offer lots of user-friendly features‚ including hand/rope holds for lowering‚ a large fill port for adding gravel (not included)‚ a check valve‚ and a sturdy strain relief to keep tubing firmly in place.

Using very little energy‚ the Robust-Aire diffuser’s rising bubbles induce flow of large volumes of water. With a standard supply of 1.5 cfm air flow‚ you can induce 1.5 million gallons of flow per day at 7 ft. And since depth increases efficiency‚ this increases to 3 million gallons at 12 feet or 4.5 million gallons at 15 feet—all without putting electricity into the water.

Compressors should be protected from weather. Post-mount and floor-mount cabinets are available for outdoor installation. Solar packages are available for Kasco fountains and surface aerators up to 2 hp, and for single-compressor diffused aeration systems. Contact us for details.

Diffusers ship fully assembled. Sure-Sink tubing kits (included) feature all necessary fittings for attaching to the compressor and diffuser assembly, and for extending length of tubing runs. For tubing runs over 300 ft, 5/8" tubing is recommended.
