Aquaculture
Aeration and process air for tanks, raceways, ponds, hatcheries and RAS
A regenerative blower moves air continuously to create pressure or vacuum. Its impeller spins without contacting the housing, there is no oil to enter the airstream. The result is a compact, reliable source of continuous air for aeration, circulation and other pressure or vacuum applications.

A regenerative blower moves air or other gases continuously to create pressure or vacuum. ROTRON blowers use a non-contacting, oil-free impeller and are available in industrial, chemical-processing and remote-drive configurations.
Yes. These blowers are built for continuous duty. Bison states over 25,000 hours of maintenance-free operation on applicable industrial models, with permanently sealed motor bearings. The manufacturer does note that a blower should not be started more than four times per hour. Check the literature for the specific model, or contact us for further information.
No. A regenerative blower moves air, which is roughly 21% oxygen. Released through diffusers underwater, that air transfers oxygen into the water and helps remove carbon dioxide. The blower supplies the air; gas transfer happens in the water.
Start with required airflow at the pressure or vacuum your system actually creates, then add electrical supply and operating environment. For aquatic aeration, diffuser air rate and submergence depth matter most, because roughly one foot of water depth is about 12 inches of water column before other losses.
