When to Use

Airmax Shallow Water Series Aeration Systems can be used in ponds 6 feet in depth or less where standard bottom diffuser aeration systems become less effective and economical. Ideal for shallow water bodies like retention ponds, the Shallow Water Series will provide continuous circulation and aeration. By aerating your pond from the bottom up, you'll circulate incredible amounts of water, drastically increasing the dissolved oxygen levels in your water column. This allows for increased levels of beneficial bacteria to accumulate in your pond resulting in reduced pond odors and muck accumulation.

How to Use

Airmax Shallow Water Series Aeration Systems can be installed at the edge of your pond or at a 115-volt power source up to 1,000 feet away utilizing Direct Burial Tubing. The Airmax Composite Cabinet protects the aeration compressor components from the elements and does not need to be placed indoors. The ProAir2 Weighted Diffuser can be connected to the SilentAir LR Series Compressor using Weighted Airline  and fitting sets. The ProAir2 Weighted Diffuser should be placed near the deepest areas of your pond and distributed equally to promote adequate aeration throughout the entire water body. Airmax Shallow Water Series Aeration Systems are designed to run 24/7 year-round but may be shut off during the winter months if desired.

Be sure to follow the included installation instructions when running your Airmax Shallow Water Series Aeration Systems for the first time.
