Aire-O2® Series II Aspirator Aerator for Aquaculture

Invest in your pond for the life of your crop


Maintaining the proper level of oxygen dispersion in your aquaculture ponds is critical to the success of your operation. Poor dissolved oxygen levels, fluctuating water temperatures, and stratification can all negatively affect fish health and pond production.

The Aire-O2 Series II Aspirator Aerator oper­ates by cre­at­ing a par­tial vac­uum under the water, draw­ing air through the shaft and dis­pers­ing it into the water in a hor­i­zon­tal direc­tion. As the pro­peller rotates, it induces a flow of atmos­pheric air through the air intake ports on the shaft located above the water sur­face. This air is then drawn through the shaft, past the pro­peller, and exits in a high veloc­ity stream of fine bub­bles as it is dif­fused into the water.
