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.

  • Produces fine bubble aeration as defined by the EPA (less than 2.2 mm in size) that insures optimum oxygen transfer efficiency
  • Distributes and uniformly mixes oxygen throughout your entire pond
  • Ideal for zero exchange systems
  • Reduce disease and mortality rates
  • Increase stocking densities, yields and profits
  • Premium high quality USA motor with specifications designed for tough environments, not plagued with problems inherent to failure ridden gear box design
  • Surface-mounted motor designed for years of trouble-free operation, not susceptible to the hazards and failures of subsurface motor types
  • New one piece unifloat insures ease of installation
  • Combined propeller/diffuser
  • Water lubricated bearing, no risk of pond contamination
  • Lightweight and portable
  • Durable flotation built to withstand harsh conditions
  • Almost maintenance-free due to design ingenuity of only one moving part
  • Made and assembled in the USA

Our equipment supports ponds by providing oxygen and mixing to disperse oxygen throughout the pond. 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.

We understand that the life of your harvest is dependent on the quality of your pond. The Aire-O2 Series II Aspirator Aerator is a propeller-type floating aerator. The aerator’s propeller injects air in a high velocity stream of bubbles defined by the Environmental Protection Agency (EPA) as “fine bubble.” The air is injected below the surface of the water and provides high velocity horizontal mixing to disperse oxygen throughout the pond.

The most impor­tant ele­ment when select­ing an aer­a­tor for aqua­cul­ture usage, regard­less of the appli­ca­tion, is oxy­gen dis­per­sion. Oxy­gen dis­per­sion involves both thor­ough sub­sur­face cir­cu­la­tion and oxy­gena­tion, to cre­ate a destrat­i­fied pond envi­ron­ment where tem­per­a­ture and oxy­gen lev­els are uni­form through­out the entire pond. This con­cept is of the utmost impor­tance to all aquatic species as it fos­ters a health­ier envi­ron­ment that will lead to increased size, increased sur­vival, and thus increased profit to the aqua­cul­tur­ist. Since species like shrimp are bot­tom dwellers, it is crit­i­cal to have the oxy­gen dis­trib­uted to the bot­tom layer of the pond where these species live and thrive. Also, thor­ough mix­ing and dis­tri­b­u­tion of oxy­gen aids in the con­trol of ani­mal and feed wastes, keep­ing pond bot­toms cleaner and decreas­ing risk of dis­ease.  The Series II is the most tech­no­log­i­cally advanced aer­a­tor in the mar­ket­place today. Its superior design allows for both mixing and oxygenation in one single unit.

The Impor­tance of Fine Bubbles

Aer­a­tion Indus­tries Inter­na­tional has spent over $1 mil­lion USD on the design and pro­duc­tion of the pro­pellers of its Aire-O2 aer­a­tors. The result of this invest­ment is that the Aire-O2 Aer­a­tor is the only aer­a­tor in the indus­try cer­ti­fied by the US EPA as a “fine bub­ble aer­a­tor.” This des­ig­na­tion means that the aver­age bub­ble size emit­ted from the Series II is less than 2.2 mm in size which is crit­i­cal to both oxy­gen dis­per­sion and oxy­gen trans­fer. The smaller the bub­ble from an aer­a­tor, the longer this bub­ble stays in the water.  And the longer the bub­ble can stay in the water, the greater the oppor­tu­nity this bub­ble has to become dis­solved oxy­gen or DO.

Proof Is in the Mixing!

The impor­tance of oxy­gen dis­per­sion and mix­ing is evi­dent from a Dye Test con­ducted at Auburn Uni­ver­sity. A 2hp Aire-O2 aer­a­tor was placed into a one acre pond. After just 32 min­utes, the entire pond was com­pletely mixed and cir­cu­lated.  Mean­while, a com­pet­i­tive 3hp sur­face splasher aer­a­tor  showed only local oxy­gena­tion and poor mixing after 80 min­utes.

Mul­ti­ple Angles of Entry

­The Series II can be adjusted from 30 degrees to 60 degrees for opti­mal mix­ing, oxy­gen dis­per­sion, and destrat­i­fi­ca­tion and is suit­able for all species and pond depths. The pho­tos below show the oper­a­tion of a 2hp aer­a­tor at var­i­ous angles of entry.

Sim­plic­ity of Design = Low Maintenance

Most aqua­cul­ture appli­ca­tions require aer­a­tion during the night, as DO lev­els are sig­nif­i­cantly lower from the day­time lev­els (due to pho­to­syn­the­sis gains from sun­light). Imag­ine being able to sleep easy know­ing that your aer­a­tion sys­tem will make it through the night with­out any emer­gen­cies! Due to its very sim­ple design, the Series II is regarded as the indus­try work­horse in terms of its reli­a­bil­ity, dura­bil­ity, and tough­ness. These unique fea­tures of the Series II include:

  • Only One Mov­ing Part — A drive shaft con­nected to the motor shaft
  • Water Lubri­cated Bear­ing — No arti­fi­cial lubri­ca­tion necessary
  • No Gear­box
  • Total of six (6) parts
  • Above sur­face pre­mium made USA motor made for tough environments

Avail­able Options:
Pro­peller Pro­tec­tion Guard  for 2hp, 3hp, 5 hp and 7.5 hp (aerator horsepower) units in any global voltage and hertz size.  Elec­tri­cal cable: SEOOW weather, UV and abra­sive resistant.

With proper use, instal­la­tion, and main­te­nance, Aer­a­tion Indus­tries Inter­na­tional war­rants that it will, at its option, repair or replace goods found to be defec­tive in mate­r­ial or work­man­ship pro­vided that within eigh­teen [18] months of ship­ment, or twelve [12] months from date of instal­la­tion, whichever occurs first. The pur­chaser gives writ­ten notice of such defect to the man­u­fac­turer at the point of ori­gin, with trans­porta­tion charges pre­paid by the pur­chaser. If an exam­i­na­tion by the man­u­fac­turer dis­closes to its sat­is­fac­tion the exis­tence of such a defect, the man­u­fac­turer will honor this war­ranty. In no event shall the man­u­fac­turer be liable for any inci­den­tal, spe­cial, or con­se­quen­tial dam­ages result­ing from said defects. The cus­tomer is respon­si­ble for elec­tri­cal instal­la­tion and meet­ing the min­i­mum stan­dards of the USNEC, and com­pli­ance with local elec­tri­cal codes.
