The Shallow Water Series SW40 aeration system is designed to improve oxygen levels and water circulation in shallow ponds where traditional deep-water aeration is not required. By delivering air to multiple bottom-mounted diffusers, the system creates rising columns of bubbles that move water vertically and help prevent stagnation.

Increased oxygen supports beneficial bacteria that naturally break down excess nutrients and organic material. This process helps reduce muck buildup, improve clarity, and lower ongoing maintenance needs, with visible improvements often seen within a single season.

Why Choose the Shallow Water Series SW40?

  • Optimized for Shallow Ponds: Designed specifically for ponds up to 6 feet deep.
  • High Oxygen Output: Linear diaphragm compressor delivers up to 4.9 CFM with low energy consumption.
  • Quiet Operation: Rubber-mounted compressor minimizes noise and vibration.
  • Flexible Installation: Can be installed at the shoreline or up to 1/4 mile away with no power required at the water.
  • Durable Cabinet: Faux rock composite cabinet protects components while blending into the landscape.
  • Low Maintenance Diffusers: Self-weighted membrane diffusers resist clogging and remain upright on the pond bottom.

System Components

  • Linear Diaphragm Compressor: High-efficiency compressor designed for continuous shallow water aeration.
  • Composite Cabinet: ETL-certified housing with elevated base, ventilation fan, rain shroud, and dual air filtration.
  • Airflow Manifold: Four-port manifold with nickel-plated ball valves, pressure gauge, pressure relief valve, and quick airline disconnects.
  • ProAir 2 Weighted Diffusers: Four diffuser plates with integrated check valves and maintenance-free sled design.
  • Weighted Airline: Optional 3/8" self-weighted airline that is kink-free and fish hook resistant.

PRO TIP

Shallow water aeration works best when diffusers are evenly spaced across the pond. Spreading airflow improves circulation coverage and helps prevent dead zones in wider or irregularly shaped ponds.
