The SD4 Solar Direct Aerator is a professional-grade, off-grid pond and lake aeration system designed for waterbodies up to 5 acres. It uses dual solar-powered compressors to deliver high-volume subsurface aeration without batteries, utility power, trenching, or a monthly electric bill.
Product Overview
Designed for larger ponds, small lakes, remote properties, and demanding water-quality applications, the SD4 converts solar energy directly into three-phase compressor power during daylight hours. Its dual brushless rocking-piston compressors produce 5.6 SCFM of airflow and supply four independently adjustable diffuser circuits. The system is housed in a rugged, powder-coated steel enclosure with active cooling, individual circuit protection, replaceable intake filters, and locking cabinet hardware for long-term outdoor service.
Key Features
What Is Included
Typical Applications
Solar-Direct Operation Without Battery Complexity
The SD4 operates directly from its solar array instead of storing energy in batteries. Eliminating batteries reduces maintenance, simplifies installation, and avoids periodic battery replacement. The system automatically responds to available sunlight and is engineered to begin operating in low-light conditions, increase output as solar energy rises, and shut down when solar production is no longer sufficient.
Installation Requirements
The installer supplies a 3-inch Schedule 40 or Schedule 80 steel mounting pole with a 3.5-inch outside diameter. Plastic pipe or tubing must not be used for the solar mounting pole. Proper site selection, pole installation, solar-array orientation, diffuser placement, airflow balancing, and airline routing are essential for best performance. The solar array should receive unobstructed sunlight and the enclosure must be installed above anticipated flood or high-water levels.
