Paddlewheel Aerators

Compare the benefits between Series II and Asian made Paddlewheel Aerators

• Circulates oxygen rich surface water by destratifying pond water column. This ensures uniform pond temperature and oxygen levels throughout the pond.

• Heavy splashing on the top layer of the pond leads to unequal temperature and DO in pond bottom (see photos above). Unable to mix depths greater than 1m.

• Water lubricated bearing requires no additional lubrication or maintenance.

• Many moving parts and questionable workmanship leads to high maintenance and repair costs.

• One moving part; only 10 parts in total.

• Many moving parts; more than 30 parts total.

• No gearbox design; thus no lubrication or frequent failures will occur.

• Gearbox design requires constant lubrication and frequent replacement.

• Lightweight, can be moved from pond to pond by only one person.

• Bulky and heavy, may take up to four people to move from pond.

• Aeration is done below surface; does not cause changes in temperature or salinity.

• Heavy splashing leads to higher salinity levels due to increased evaporation rates.

• Hi-tech composition materials with corrosion free elements. Materials for Series II aerator used in aerospace and automotive industry.

• Many parts are made of galvanized steel, aluminum and low grade stainless steel - all of which corrode quickly in pond environment.

• Able to adjust angle for shallow or deep ponds.

• Only able to aerate shallow ponds.

• Viewed by industry as a farm investment.

• Viewed by industry as pond consumable

• Operates level with fluctuating water levels

• Must be leveled periodically or amperage draw increases.

• Precision engineered to stay afloat in all weather conditions.

• May tip over on windy days.

• Standard 1 year warranty; strong customer service and field service departments.

• Warranties are suspects; little customer service

• Made in USA, quality craftsmanship

• Of questionable quality and workmanship.

Compare the benefits between Series II and Submersible Aerators

• EPA defined ‘fine bubbles’ allow for maximum oxygen dispersion and oxygen transfer throughout pond

• Aerator emits large bubbles which float immediately to the surface (see photos above).

• Surface mounted motor ensures no contact with corrosive water in pond.

• Submersible motors suspect to failure and leakage, especially if cycled off and on daily.

• Able to mix fine bubbles deep below the surface throughout the entire pond in one unit.

• Due to submersible design, additional stationary mixers are often necessary for assistance in mixing.

• Available in multiple sizes (1 – 7.5Hp)

• Largest sized aerator is 2.2 Hp

• Hi-tech propeller design ensures smooth operation.

• Heavy cavitations occur on propeller during operation

• One year warranty on equipment

• Suspect warranty policy and long parts delays

• Actual operating power is 90-95% of motor name plate; thus giving the farming what they are paying for and need for their application

• Actual operating power is 67-80% of motor name plate; thus deceiving customer from what they are actually purchasing and require for their application

• Hi-tech composition materials with corrosion free elements. Materials for Series II aerator used in aerospace and automotive industry.

• Made of cheap plastics very susceptible to breakage and short lifetimes.

• No efficiency loss due to simple direct drive hollow shaft aspirator design.

• Tremendous loss of efficiency due to power wasted from sucking air above waters surface down to the submersible motor.

• Able to mix all sizes / depths of ponds due to multiple angle design and large scope of equipment (1-7.5 Hp). Small sized fine bubbles allow for maximum dispersion.

• Unable to mix deep waters as the deeper you lower the motor, the less efficient the aerator performs. Also, large bubble immediately escape to water surface.

• Numerous independent tests worldwide; proven and trusted to the industry for over 30 years!

• Lack of independent testing; relatively short history

Compare the benefits between Series II and Asian Imitation aspirator

• Specially Designed Propeller For Aeration

• Use Cheap Off the Shelf Marine or Boat Propeller

• EPA defined ‘fine bubbles’ allow for maximum oxygen dispersion and oxygen transfer throughout the entire pond

• Aerator emits large bubbles which rise immediately to the surface (see photo above)

• Experts in aspirator aerators to the aquaculture industry; we only work with the best!

• Companies peddle many different types of aerators to the Industry; not focused on selling quality

• Engineered Propeller Means Smooth Operation and Low Maintenance

• Propellers Causes Cavitation, Vortexing and Vibration Leading to Shorten Aerator Lifetime

• Due to Design, Much Higher Oxygen Transfer and Mixing

• Very Poor Oxygen Transfer and Mixing

• 378 m3 test pool facilities and R&D Center

• Questionable testing facilities and product expertise

• Multiple Aerator Sizes (1-7.5Hp) for aquaculture and wastewater treatment (up to 150 Hp)

• Only Have 1 and 2 Hp sizes

• Numerous independent tests worldwide; proven and trusted to the industry for over 30 years!

• Lack of independent testing; relatively short history

• Pioneers of the Aspirator Technology with over 30 years of experience!

• Made From A Company Who Are Not Aeration Experts
