The Flojett FJ-PW204 is a 2 HP 4 paddle wheel aerator designed for fish ponds, shrimp farms and surface water aeration. Powered by a 1.5 kW motor and equipped with four 670 mm impellers, it provides an aeration capacity of at least 2.6 kg O₂ per hour while promoting continuous water circulation.
Its IP65 motor, Class H insulation, UV-resistant plastic components and 304 stainless steel structure make it suitable for long-term operation in demanding aquaculture environments. Contact Flojett for specifications, configuration advice and current factory pricing.
2Hp 4 paddle wheel aerator can be used in both small and large aquaculture ponds or water treatment system. Below are the main features of 2hp 4 paddle wheel aerator of model FJ-PW204:
Durability: Designed for robust and stable operation in varying environmental conditions. IP65 standard, H-grade insulation and protector inside ensure the motor can work under high temperature stable and better water proofing. Mechanical seals prevent oil leaking and NSK bearings inside make the gearbox working long lifespan and smoothly.
Material promise: All plastic parts are made of 100% new raw plastic and UV resident. All stainless steel promise using stainless steel 304.
Long time warranty and after sell service: we offer 2 years warranty and whole using life after sell services.
High Oxygenation Efficiency: Provides consistent oxygen supply for aquaculture ponds or waste water treatment system.
Cost-Saving: Relatively low operational and maintenance costs.
Enhanced Water Quality: Raises dissolved oxygen level, reduces harmful gases, and prevents water stratification.
Easy to Handle: Easy installation and operation, suitable for all sizes of aquaculture farms and waste water treatment system.

Voltage and electrical configurations should be confirmed before ordering because availability may depend on the destination market and project requirements.
The FJ-PW204 is suitable for surface aeration and water circulation in:
Fish farming ponds
Shrimp and prawn ponds
Aquaculture nursery ponds
High-density stocking ponds
Reservoir and lagoon aeration
Wastewater equalization or treatment ponds
Emergency oxygenation during hot weather
The required number of aerators depends on pond area, water depth, stocking density, species, biomass, feeding rate and local climate. A pond should not be sized by motor power alone.
Green color high efficient impeller is another good choice for all paddle wheel aerators. Further more, we also provide plastic gear reducer and permanent magnet motor for upgrading the paddle wheel aerator, just feel free to contact us for more information!
A 2 HP four-impeller configuration provides a practical balance between oxygenation capacity, circulation coverage and operating cost. Compared with smaller two-impeller units, it can create a broader water-flow pattern. Compared with larger 3 HP systems, it may be easier to deploy flexibly across different pond zones.
The FJ-PW204 may be suitable when you need:
More circulation than a 1 HP two-impeller aerator
Flexible placement across medium or large ponds
Standard three-phase motor operation
Replaceable modular components
Durable stainless steel and UV-resistant materials
Final selection should be based on the pond conditions and required oxygen demand rather than horsepower alone.
The 2 HP 4 paddle wheel aerator price depends on the motor voltage, order quantity, material configuration, packaging requirements and shipping destination. Optional upgrades, such as a permanent magnet motor, plastic gear reducer or high-efficiency impellers, can also affect the final quotation.
For an accurate factory price, please provide:

Flojett can provide a quotation based on your pond aeration needs and purchasing volume. Contact our sales team for the current FJ-PW204 price, lead time and shipping details.
The rated aeration capacity is at least 2.6 kg O₂ per hour. Actual pond performance may vary depending on water depth, temperature, salinity, installation and operating conditions.
The price depends on quantity, voltage, motor configuration, optional components, packaging and shipping destination. Contact Flojett with your requirements for an accurate factory quotation.
Yes. It can be used to increase dissolved oxygen and generate water circulation in shrimp and prawn ponds. The required quantity should be calculated according to pond conditions and stocking density.
The listed voltage range is 110–440 V with 50/60 Hz availability. The required voltage and phase should be confirmed before production.
The floats and motor cover are made from UV-resistant virgin HDPE, the impellers use UV-resistant virgin PP, and major structural metal components are made from 304 stainless steel.
The quantity depends on pond size, depth, species, stocking density, biomass, feeding level and target dissolved oxygen. Provide these details to Flojett for a more accurate recommendation.
Yes. Flojett states that the product includes a two-year warranty and long-term after-sales support.
