Splash Aerator for Sale

Compare the Three Flojett Splash Aerator Models

All three models address the same core problem — low DO in fish and shrimp ponds — but differ in structure, impeller design, maintenance needs, and aeration output. Use the table and notes below to match the right unit to your pond and management style.

How to Choose Between the Three Models

Choose FJ-WC if:

You want the lowest initial and maintenance cost — no gearbox, no gear oil changes

Your pond requires 3 HP (2.2 kW) output — only the FJ-WC offers a 2.2 kW variant

You prioritize lightweight, easy relocation between ponds

Environmental protection matters — zero risk of gear oil contamination

Choose FJ-WS Surge if:

You need consistent, higher-torque output — the planetary gear system runs more smoothly and lasts longer under continuous heavy use

Your stocking density is higher and you want the stainless steel impeller's durability

You're operating in a tilapia or carp pond where the unit runs 12+ hours daily

Budget allows for periodic gear oil maintenance in exchange for mechanical longevity

Choose FJ-SI Super Impeller if:

Your electrical supply is unstable — the built-in overheating and phase-loss protector auto-shuts the unit before motor damage occurs

You want the most flexible parts ecosystem — impellers are available in SS304 or nylon, and motors in water-cooling, cast iron, or permanent magnet options

You're scaling up and want units that can be reconfigured for different pond sizes or power supplies

You manage multiple species across different farms and need a single model that adapts

Contact Flojett with your pond dimensions, fish species, and stocking density for a site-specific recommendation.

What Problems Can a Splash Aerator Solve?

• Low dissolved oxygen during peak feeding periods or warm summer nights

• Surface stratification — stagnant top layers with poor circulation

• Toxic gas buildup (CO₂, H₂S) near the water surface

• Slow fish growth and poor feed conversion caused by chronic mild hypoxia

• Fish kills during weather events that suppress natural oxygen exchange

• Inadequate aeration coverage in small or shallow ponds where diffuser hose installation is impractical

  
  

Advantages of Splash Aerator for Sale

• Effective at increasing surface dissolved oxygen levels.

• Can provide some degree of water circulation and mixing, especially near the unit.

• Relatively simple design and often lower initial cost compared to some other types.

• Can help in degassing harmful gases from the water surface.

• Visually indicates operation.

• Can be relatively easy to install and move.

How Does a Splash Aerator Work?

A splash aerator increases dissolved oxygen (DO) through surface agitation and air-water contact. The motor drives a high-speed impeller that scoops water from below the surface and throws it upward as a wide spray. As the droplets travel through the air, oxygen transfers across the expanded water-air interface. When the droplets fall back into the pond, they carry the absorbed oxygen down into the water column.

Unlike submersible diffusers that aerate from the bottom up, or paddle wheel aerators that sweep horizontally, splash aerators concentrate oxygen input at the top 30–60 cm — the zone where fish and shrimp spend most of their time and where DO depletion happens first during hot nights or after overcast days.

The process also degasses harmful dissolved gases — carbon dioxide and hydrogen sulfide — that accumulate near the surface, which further improves water quality beyond DO alone.

Where Are Splash Aerators Used?

Splash aerators are best suited to open, shallow-to-medium-depth ponds (typically 0.8–2.5 m water depth) where surface aeration alone is sufficient to maintain adequate DO throughout the water column. Key application environments include:

• Tilapia, grass carp, carp, and catfish farming ponds

• Shrimp ponds (vannamei and black tiger shrimp) — particularly as supplemental aeration alongside paddle wheel units

• Small-scale aquaculture operations under 2 acres where a single unit covers the entire pond

• Wastewater treatment ponds requiring cost-effective surface aeration

• Emergency backup aeration during power-cut recovery or extreme weather

For deeper ponds (>2.5 m) or high-density intensive shrimp operations, combine a splash aerator for surface oxygenation with a jet aerator or aeration hose diffuser system to reach the deeper water column.

Installation and Placement of Splash Aerators

• Positioning for optimal surface agitation and localized circulation.

• Ensuring proper water depth for the unit to operate effectively.

• Anchoring floating units securely.

• Electrical connections and safety.
