– These micro pores allow air to pass through them with the greatest ease, continuously creating a vast amount of microbubbles—at an average size of 3 mm each—in the water. Aero-Tube®’s microbubbles maximise the surface area of the water, exposing more of it to the air where oxygen transfer takes place. This results in a significantly higher rate of oxygen transfer than conventional aeration systems.

– Microbubbles also take longer to rise in water and stay intact in the water longer. This gives the bubbles prolonged exposure to the water, providing an abundance of dissolved oxygen through the bubble-water interface instead of breaking at the surface and releasing the oxygen into the atmosphere.

– Not only is this important to aeration, but it also improves water quality. In aquaculture applications, for example, the water circulation created by Aero-Tube® helps keep solids for fish and shrimp suspended for consumption instead of settling at the bottom of the tank, where they can produce harmful ammonia and nitrates.

– Because of Aero-Tube®’s highly porous surface, it offers little resistance to the air pushing through its tiny pores. This means you need less energy to get the air into the water, resulting in much lower energy usage and expense. In fact, in performance tests with traditional aeration systems such as paddlewheels, Aero-Tube® reduces energy costs by up to 75 per cent!

– Aero-Tube® also saves you money by being a low-cost, low-maintenance product. Compared with other aerations systems, Aero-Tube® is considerably less expensive to start up. And with no moving parts, Aero‑Tube® requires much less maintenance. For instance, paddlewheels, aspirators and other aeration technologies require regular—and sometimes extensive and expensive—upkeep and repairs.

– Swan’s Aero-Tube® has thick, flexible walls that will not break, even if stepped on! It’s also anti-algal and antibacterial, allowing it to resist clogging and remain in top working condition with just a rinse from a power hose. This makes Aero-Tube® incredibly long-lasting—for as long as 10 years!
