NOVAEOS AC-LA4 Aerator

NOVAEOS AC-LA4 Aerator

The NOVAEOS AC-LA4 is a high-output 120-volt electric pond and lake aerator for ponds up to 4 acres, built around a 1/2 HP USA-made rocking piston compressor, four DB-36 stainless steel diffusers, and a purpose-built AC-Series enclosure designed for quiet, serviceable, long-term outdoor operation.

For ponds where utility power is available, AC-powered aeration provides dependable oxygen transfer day and night at a low operating cost. The AC-LA4 is the four-diffuser AC-Series model, making it a strong choice for larger ponds that need multiple diffuser locations to improve circulation, reduce stagnation, and move oxygen into more areas of the lower water column.

The AC-Series was engineered from the ground up around the details that matter in real installations: airflow, temperature management, sound control, filter access, compressor access, mounting flexibility, pressure monitoring, individual diffuser balancing, and optional startup control. This is not a generic compressor in a metal box. It is a complete electric pond and lake aeration system built for professional installations and long-term service.

A Purpose-Built Aerator Enclosure

The AC-Series enclosure is one of the strongest advantages of this system. It is laser cut, formed, welded, powder coated, and designed specifically for aeration equipment. The cabinet provides excellent ventilation, screened and protected exhaust, lockable access, quiet operation, clean fit and finish, and easy access to the compressor, filters, pressure gauge, manifold, and controls.

Standard mounting allows the AC-LA4 to be pole, post, or wall mounted. An optional ground-mount base kit is available for installations where a freestanding cabinet on a mounting pad is preferred. That flexibility makes the AC-Series suitable for residential ponds, farms, parks, HOAs, golf courses, commercial sites, and other pond or lake aeration installations.

Factory-Installed Controls Other Brands Do Not Offer

The AC-LA4 can be factory-equipped with a digital time clock and/or USSM automatic Slow Start control. Slow Start gradually ramps up aeration during startup to reduce the risk of rapidly mixing low-oxygen bottom water into the upper water column. This is especially important for new installations, seasonal restarts, or ponds with severe stratification.

Optional high-temperature limit controls are also available to help protect the system from overheating. These options give the AC-Series a level of startup control, scheduling, and equipment protection that is uncommon in standard AC pond aerators.

Designed for Serviceability and Air Balancing

Routine maintenance is simple and accessible. The AC-Series includes dual easy-access washable enclosure filters, dual compressor intake filter/silencers with replaceable filter cartridges, a built-in liquid-filled manifold pressure gauge, screened exhaust protection, and individual air balancing valves. The AC-LA4 includes four external air outlets and four full-flow balancing valves so each diffuser run can be adjusted for proper system performance.

Aerators must be supplied by a 120-volt, 15- or 20-amp GFCI-protected circuit. The installer is responsible for ensuring proper voltage at the compressor while the unit is running under load.
