• Diffused Lake Aeration System

  • This highly efficient lake aerating system features a land based air compressor and one submerged 2 disc air diffuser manifold for effective, non-intrusive aeration of lakes and large ponds.

    • Ideal for large water bodies such as ornamental lakes, fisheries, effluent ponds and golf courses
    • Minimal visual disturbance of the lake water surface
    • Minimal water evaporation as no water is ejected into the air
    • Helps to break down temperature layering of warmer surface water, minimising algal growth
    • Effectively circulates the entire water body
    • Rising air columns oxygenate the water, assisting bacteria which feed on algae and organic nutrients
    • Operating depths from 1 metre (4ft) down to 12 metres (40ft). Greater depths can also be catered for.
    • Submersed disc air diffusers are virtually maintenance free
    • No electrical parts entering the water, safe for recreational use in swim ponds
    • Robust, quiet, weatherproof air pump is extremely energy efficient with minimal running costs
    • Single phase, 230 volt air pump makes installation more practical
    • Multiple ponds or lakes can be aerated via one single air pump feeding multiple air diffusers.

  • The system becomes more effective the deeper the air diffusers are submerged. This lake aeration system is capable of aerating the following lake sizes:
    • Up to 2,023m² lake surface area at 2.4m - 7.9m diffuser installation depth
    • Up to 4,027m² lake surface area at 4.3m - 7.9m diffuser installation depth
    • Up to 12,140m² lake surface area at 5.8m - 12.2m diffuser installation depth

    The capability of the system can be increased to suit larger water bodies by connecting additional diffuser manifolds.

  • The Standard Diffused Lake Aeration System includes the following:

  • Weatherproof, stainless steel housed air compressor
  • Submersible air manifold featuring 2 large disc air diffusers
  • 30 metre un-weighted air hose for land based air transportation
  • 30 metre weighted air hose for underwater air transportation
  • Valved manifold box for air flow control and hose connection
  • 30 metres of 230 Volt / Single Phase power connecting cable

Diffused Lake Aerating System - Performance Data

The Diffused Lake Aerating System is supplied with a single air diffuser manifold featuring 4 self-cleaning air domes. Based on different depths of diffuser submersion, this system is suitable for aeration of the following lakes sizes (surface area).

Diffused Lake Aerating System (single 4 dome diffuser manifold)

Diffuser Submersion Depth

Maximum Lake Surface Area Coverage

2.4m – 7.9m


4.3m – 7.9m


5.8m – 12.2m



The set lake aeration system can be modified to suit larger or shallower water bodies with the introduction of a second 4 dome air diffuser manifold. An aeration system featuring 2 diffuser manifolds will be suitable for the following lakes/depths.  

Diffused Lake Aerating System (with additional 4 dome diffuser manifold)

Diffuser Submersion Depth

Maximum Lake Surface Area Coverage

1.2m – 2.1m


2.4m – 4.3m


4.3m – 12.2m



The introduction of a third air diffuser manifold will increase the systems capability still, making this system more effective for larger lakes when the diffusers are submerged in shallower water. A system featuring 3 air diffuser manifolds will suit a body of water up to 12,140m² with the diffusers installed in as little as 2.4m depth of water.

Diffuser Submersion Depth

Maximum Lake Surface Area Coverage

2.4m – 4.3m



For lakes exceeding 12,140m², a second air compressor/diffuser system can be introduced to increase the dissolved oxygen input. For more information on aeration specification of larger water bodies, contact us by telephone or email for expert advice.
