Kasco Robust-Aire™ Diffusers

Pond Aeration Canada

Ackenberry Trout Farms use Robust-Aire™ Diffusers and Pond Aeration Systems on many of their pond and lake aeration projects in Canada, Alberta, British Columbia, Saskatchewan, and Manitoba. 

Robust-Aire™ Diffusers were independently tested with respect to water flow in comparison to 6 designs by 4 other industry leaders. Robust-Aire™ created betwen 10% and 44% additional water flow, making it the most efficient diffused aeration system on the market. 

Not only are they the most efficent but Ackenberry is offerning these units at the best wholesale price.  Compare our pond aeration Canadian systems.

Kasco Robust-Aire™ DiffusersAeration is key to predictable performance from your pond. Your pond environment receives life-supporting oxygen from the atmosphere at the surface where the air and water contact each other, as well as from the photosynthesis of algae and plants below the water surface.

These processes are both affected by weather: available wind energy (wave action) and sunlight. Weather is unpredictable and that can create stagnant water and low oxygen levels. When there is no sunlight, there is no photosynthesis to create oxygen. In stagnant water, there is no physical energy to help the water and air exchange gases and water forms well defined layers of different temperatures. Poor environmental conditions in the pond for fish and other organisms are the result.

robust-aire-underwater-lowrAeration dramatically improves environmental conditions in your pond and helps keep good water quality predictable. Beneficial bacteria reduce sludge and nutrients, and there are reduced incidences of undesirable algae and odors. Winter ice is not allowed to seal the pond surface and restrict oxygen and gas transfer. Aeration allows your fish to thrive in an optimal environment and fish populations experience improved growth rates and vigor.

Robust-Aire™ diffused air systems provide deep water aeration for ponds and lakes. Diffused aeration is an effective method of aeration for ponds with depths greater than 8 feet. By using compressed air injected directly into the bottom of pond, a continuous flow of water is moved upward and thousands of gallons of water are mixed with little expended energy. A Robust-Aire™ energy efficient compressor injects air to the bottom of your pond with weighted, SureSink™ air line and into the Robust-Aire™ diffuser assembly. The diffuser breaks up the air into micro bubbles which rise to the surface. The rising of the air bubbles creates current which transfers low-oxygen water to the surface, allows it to contact the atmosphere, and breathe. Temperature layers are disrupted and fish are able to inhabit the entire water column. Oxygen levels increase and harmful gases in the pond water are expelled.

There is no disruption of the serenity of your pond setting, just the assurance that it is getting the oxygen that it needs.

 Advantages of using a Robust-Aire System

  • No electricity in the water. This can be especially important where swimming is allowed.

  • No floating equipment at the surface. Boating is not hindered and the natural view of the lake can be enjoyed.

  • No electricity needed at the edge of the pond or lake. Robust-Aire can be remotely installed away from the water’s edge. Air can be delivered to the water’s edge instead of electricity. This can result in an installation cost savings. This option may be preferred where it is more convenient to have the compressor system consolidated with other equipment.

  • Robust-Aire™ is more effective at aerating deeper waters than a floating fountain or high-volume surface aerator. Robust-Aire™ becomes effective at 8 feet of depth and increases efficiency with respect to water flow at the water deepens. Water is pumped directly from the bottom, all the way to the top. Robust-Aire compressors can inject air 50 feet deep!

  • Robust-Aire™ is cost effective to purchase and operate for larger surface areas. These systems can effectively destratify and aerate deep lakes with much lower equipment costs and energy consumption. Robust-Aire™ systems are the most efficient on the market.

  • Low maintenance. Most maintenance and inspection may be conducted onshore. Rocking piston compressors do not require internal maintenance as often as other compressors.

"The day after the system was turned on, phosphorus levels on the bottom were decreased and the pond was chemically and thermally destratified." - Gordon Gotch, Assistant Biologist, Mac McGraw Wildlife

"The New Kasco RA unit was installed successfully at St. Francis Hospital. I believe this new bottom aeration unit will outperform every other bottom aeration unit on the market today based on price, quality, and ease of installation. I especially like the new diffuser head and small weighted air tubing!" - Installer in SC
