FUTI 18 Impellers 4KW 5HP Long Arm Paddle Wheel Aerator

Maximize Oxygenation, Boost Growth, and Ensure Healthy Aquaculture Dissolved oxygen

Product Overview

Designed specifically for large-scale fish and shrimp pond farms, the 18-Impeller 4KW (5HP) Paddle Wheel Aerator is a powerhouse solution to combat low dissolved oxygen (DO), stagnant water, and poor water quality. With 18 high-efficiency PA plastic impellers and a robust 4KW motor, this aerator delivers unmatched oxygenation and water circulation, ensuring optimal conditions for fish and shrimp growth, even in high-density farming environments.

Why Fish & Shrimp Farms Need This Aerator

• Prevent Hypoxia: High-density fish/shrimp farming rapidly depletes oxygen. This aerator maintains DO levels above 5 mg/L, critical for survival and growth.
• Reduce Mortality: Eliminate “dead zones” and prevent mass die-offs caused by oxygen crashes, especially during hot seasons or algal blooms.
• Accelerate Growth: Enhanced oxygen levels boost metabolism, feed conversion rates, and harvest weights.
• Improve Water Quality: Break down ammonia, nitrites, and organic waste by promoting aerobic bacteria activity.
• Energy-Efficient Operation: 4KW stainless steel motor consumes 30% less power than traditional models, slashing operational costs.

Key Features for Fish & Shrimp Farming

1. 18 Heavy-Duty PA Plastic Impellers

• Corrosion Resistance: PA plastic blades withstand saltwater, pond chemicals, and organic acids, ideal for shrimp farms.
• Lightweight & Durable: Reduces motor load by 15%, extending motor lifespan.
• Anti-Clog Design: Smooth surface prevents algae or debris buildup, common in nutrient-rich ponds.
• Large area aeration, the long arm 18 Impeller aerator is suitable for large area pond.

2. 4KW (5HP) High-efficiency Motor

• 24/7 Durability: Built for continuous operation in humid, salty environments (perfect for coastal shrimp farms).
• Overload Protection: Automatically shuts off during voltage spikes or mechanical stress, protecting your investment.

3. Adjustable Depth & Flow Control

• Tailored Submersion: Adjust impeller depth (10–30 cm) to match pond depth—ideal for shallow shrimp ponds or deep fish reservoirs.
• Directional Flow: Steer currents to flush waste toward drainage points, keeping ponds clean.

4. Corrosion-Resistant Build

• Saltwater-Ready: Galvanized steel frame, UV-stabilized HDPE floats, and PA plastic components withstand harsh aquaculture conditions.
• Low Maintenance: Sealed bearings and waterproof wiring minimize downtime.

Technical Specifications

Applications in Fish & Shrimp Farming

For Fish Ponds (Tilapia, Carp, Catfish)

• Summer Survival: Combat oxygen depletion during hot weather when fish metabolism peaks.
• Waste Management: Circulate water to disperse fish excrement and uneaten feed, reducing sludge buildup.
• Disease Prevention: Aerobic conditions inhibit pathogens like Aeromonas and Columnaris.

For Shrimp Ponds (Vannamei, Tiger Shrimp)

• Molting Support: High DO levels are critical during shrimp molting phases to prevent soft-shell mortality.
• Algae Control: Disrupt algal stratification to prevent toxic blooms and pH swings.
• Post-Larval Growth: Boost survival rates in nursery ponds by maintaining stable oxygen.

Installation & Maintenance

Farm-Ready Setup

1. Float Assembly: Attach HDPE floats to the frame—no tools required.
2. Motor Mounting: Secure the 4KW motor centrally for balanced operation.
3. Depth Adjustment: Set impellers to 15–20 cm submersion for shrimp ponds or 25–30 cm for deeper fish ponds.
4. Power Connection: Compatible with Power source

Low-Effort Maintenance

• Daily Check: Inspect PA blades for debris (wipe clean with a brush if needed).
• Monthly Service: Lubricate bearings and tighten bolts.
• Annual Overhaul: Replace worn PA blades (spare parts kit included).
