Scott Aerator Solar Subsurface Aeration System

The Scott Aerator Solar Subsurface Aeration System brings diffused-air aeration to ponds that have no electrical service nearby. There is no grid connection, no AC wiring run out to the water and no battery bank in the standard configuration — a pole-mounted solar module powers the compressor directly, and the system continues to produce air under overcast skies rather than waiting for full sun. For remote stock ponds, back pastures, stormwater basins and golf course water features, that removes the trenching and electrical work that normally decides whether a pond can be aerated at all.

The standard system runs a single 300-watt, 60-cell module feeding one high-efficiency brushless rocking-piston compressor, which supplies two self-weighted diffusers through a 300-foot airline. Air released at the pond bed rises as a bubble column, lifting oxygen-depleted bottom water to the surface where it vents accumulated gases and takes on oxygen before circulating back down. The compressor is rated at 2.5 SCFM and will work in water beyond 30 feet deep at 25 psi, and it covers ponds up to roughly 2.5 acres.

Scott Aerator built the system around a brushless compressor specifically for service life, stating it runs more than three times longer than the brushed permanent-magnet motors commonly used in solar aeration. The supporting hardware is specified in the same vein: an all-welded powder-coated steel base, a fiberglass-reinforced enclosure, stainless steel locking hasps and hardware, rubber isolation mounts under the compressor to cut vibration, and a washable, reusable air intake filter. Automatic active ventilation moving 78 CFM keeps the cabinet interior from heat-soaking in summer, and the unit runs under 65 dB measured at six feet.

Control and plumbing components sit inside the enclosure: rocker-style circuit breakers, a brass automatic pressure relief valve, a liquid-filled stainless steel pressure gauge for reading system back pressure at a glance, and two full-flow brass ball valves so airflow can be balanced between the two diffusers. Air connections are made at external ports, so the airline can be attached without opening the cabinet. Components are American-made and every unit is fully factory tested before it leaves the plant.

What's Included and What You'll Need

• Included: one 300-watt 60-cell solar module, 39 by 65 inches, with adjustable top-of-pole racking
• Included: brushless rocking-piston compressor in a fiberglass-reinforced, vented enclosure on a welded steel base
• Included: one 3/8-inch by 300-foot airline and two self-weighted diffusers
• Included: brass automatic pressure relief valve, liquid-filled stainless pressure gauge, two full-flow brass ball valves and rocker circuit breakers
• Not included: the vertical galvanized mounting pole, roughly 10 feet long and 3 inches nominal (3 1/2 inch OD), which is required for the panel and racking
• Optional: a 48-volt backup battery module giving up to three days of aeration without sun, with MPPT charge control over Bluetooth, a digital time clock and automatic ventilation. It requires a two-panel array, so ordering it upgrades a standard system to two modules.
