The OxiAir HD diffused lake aerator is designed and developed with depth in mind and can aerate lakes up to 10m+ deep.

The super-silent bankside compressor pumps air through the diffuser membranes situated on the lake bed. This air travels up through the water column and breaks through the thermocline, reducing the effects of thermal stratification. Diffused aeration mixes the water column efficiently and increases the dissolved oxygen levels within a lake. At a depth of 2m, each diffuser circulates an approximate volume of 11,065 litres of water per minute.
