Oxygen Generator for Fish Farm Key Features
Oxygen Supply Core: Dual-effect aeration, 1.5-3 meter aeration depth, 30% higher dissolved oxygen efficiency than traditional methods, raising dissolved oxygen in a 1000㎡ fishpond from 3mg/L to over 8mg/L in 1 hour; single unit covers 500-2000㎡, 360° coverage without dead zones, preventing localized oxygen deficiency.
Energy Saving Advantages: Pure copper core waterproof motor , efficiency over 90%, 20%-25% more energy-efficient than aluminum core motors, saving 30-150 yuan per month in electricity costs; optional intelligent start/stop, compatible with dissolved oxygen detectors, avoiding ineffective operation.
Durable and Adaptable: The 304 stainless steel and engineering plastic body is corrosion-resistant and wear-resistant, suitable for 5-8 years in freshwater/slightly brackish water; the motor is IP68 waterproof, leak-proof and overheat-proof, with a weighted base for stability, suitable for harsh environments such as ponds, net cages, and factory aquaculture.
Operation and Maintenance: No installation required, simply open the box, add water and power; comes with a 5-15 meter thickened waterproof cable; core components are detachable, requiring only simple tools for daily maintenance, no professional personnel needed.
Aquaculture Value: Increases fish and shrimp survival rate by 15%-30%, improves feed conversion rate by 10%-20%, allows for earlier market entry by 7-15 days, reduces harmful substances such as ammonia nitrogen, and lowers aquaculture risks and costs.
FAQ
1. What types of aquaculture scenarios is this oxygen generator suitable for?
It is widely applicable to freshwater fish ponds, marine shrimp tanks , crab ponds, frog ponds, industrial recirculating aquaculture, cage aquaculture, and rice-fish co-culture. It adapts to both small ponds and large-scale aquaculture water bodies, and performs stably in high temperature, rainy days and other oxygen-deficient environments.
2. How to choose the right model for my fish farm?
Select models based on your pond area and water depth: For 500-800㎡ ponds, choose 0.75KW; 800-1200㎡ for 1.5KW; 1200-1600㎡ for 2.2KW; 1600-2000㎡ for 3.0KW; and 2000-3000㎡ for 5.5KW. If the water depth exceeds 2 meters or the stocking density is high, it is recommended to choose a model with higher power to ensure sufficient oxygen supply.
3.What is the actual energy-saving effect, and how much electricity can be saved per month?
Equipped with pure copper core motors, it saves 20%-25% energy compared with ordinary aluminum core motor oxygen generators. Taking daily operation of 8 hours as an example: the 0.75KW model saves about 30 yuan/month, the 2.2KW model saves 80-100 yuan/month, and the 5.5KW model saves up to 150 yuan/month . The optional intelligent start/stop function can further reduce invalid energy consumption.
4.How durable is the product, and can it withstand long-term immersion in water?
The body is made of 304 stainless steel + engineering plastic, and key components such as impellers are anti-corrosion and anti-wear treated. It can be immersed in fresh water or slightly brackish water for a long time, with a service life of 5-8 years. The motor has IP68 waterproof rating, with anti-leakage and overheating protection, and can operate stably in harsh weather such as storms.
5. Is installation and maintenance complicated? Do I need professional personnel?
It adopts installation-free design-unbox, put into water, and connect to power to use, no complex assembly required. The equipped thickened waterproof cable meets different power supply needs. Core components are detachable; daily cleaning and replacement only need simple tools , and no professional technical personnel are required, which greatly reduces maintenance costs.
