AIRE - O2 Aspirator Aerator
The Aire-02® Series 2 Aquaculture 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.
AIRE - O2 Aspirator Aerator Information
The Aire-O2® Series 2 operates by generating a partial vacuum below the water surface, drawing atmospheric air through a surface-mounted shaft and expelling it as a high-velocity stream of fine bubbles. This efficient horizontal dispersion of oxygen-rich microbubbles (less than 2.2 mm, EPA-defined) ensures optimal oxygen transfer and uniform mixing throughout the pond.
Engineered for durability and simplicity, the unit features a high-quality USA-built motor, a combined propeller/diffuser, a water-lubricated bearing system (eliminating contamination risks), and a robust unifloat construction designed for harsh conditions. With only one moving part and no gearbox or subsurface motor, it offers near maintenance-free performance and avoids common failure points seen in conventional aerators.
Ideal for zero-exchange and high-demand aquaculture systems, the Aire-O2® Series 2 promotes higher stocking densities, improved yields, and reduced disease and mortality rates—ensuring long-term reliability, easy installation, and superior water quality management.

Areas of use
The original Aire-O2 Aerator was designed and patented in 1974 to prevent fish kills as the lakes in Northern USA froze over each winter. The mixing kept the frozen layer at bay and the oxygen ensured that the fish were able to survive the winter. The Aire-O2 Aspirator Aerator quickly became the go to machine for lake restoration and water control in ponds.
Funcionality
The Aspirator uses a high speed motor to drive a propeller at the end of a HOLLOW shaft. This causes a vacuum effect and pulls atmospheric air down the shaft, which is then broken down into 2,2mm sized bubbles and pushed into the water body. This directional aeration ensures that even large water bodies can be controlled by this mixing and aeration device.
Series 275
The series 275 Aspirator is a workhorse and the most popular aerator on offer. Available from 1,5 up to 5,5 kW only. This model has the same essential design features and advantages of the original Aspirator. Offering a shortened stainless steel shaft and one-piece unifloat allows this aerator to be extremely cost effective while also being small and light enough to be carried in comfort by two people, yet powerful enough to treat surprisingly large ponds. The Series 275 aspirator aerator is the first choice in the upgrade of Oxidation ponds in South Africa for municipalities, sports lovers and farmers alike.
