The a3®  Aeration Nozzles are simplicity at its finest. They combines aeration, degassing, circulation, and mixing all in one package and more importantly one energy source.

This truly versatile system is a perfect solution for everything from increasing the density and health of outdoor ponds to eliminating water exchange and pure oxygen in indoor tanks and super-intensive raceways. Add to the system, and manage processes like fine-protein removal as well. 

Used in all culture stages  nursery, brood-stock and grow-out. Contact us for your custom solution.


We use the power of the pump to recirculate the water through our patented nozzles naturally aspirating ambient air at 3X’s the volume of water being pumped. That huge volume of air is then sheared into the finest of mircobubbles resulting in a high dissolved oxygen transfer rate.


This high air to water ratio strips CO2 from the water allowing the respiratory system to absorb more oxygen and increase metabolism. Creating a naturally alkaline blood stream results in healthier faster growing animals and reduces mortality caused by disease.


Energy isn’t spent in compressing air, it’s used to move water creating a more natural ow and is adjustable by turning the direction of the nozzle(s). Positioning the nozzles at the bottom of the water isn’t just for improved DO transfer, it also keeps solids in suspension and from creating problematic areas that may generate H2S hydrogen sulphide.
