High-density recirculating aquaculture demands consistent dissolved oxygen levels to sustain healthy fish and shrimp growth. Our 20L PSA industrial oxygen generator produces high-concentration oxygen on demand, perfectly matching the operation requirements of indoor RAS farming systems. Replace costly bottled oxygen, stabilize water environment, cut operating costs and realize sustainable intensive aquaculture.

- How 20L PSA Oxygen Generators Improve Production of Indoor Recirculating Aquaculture Systems
Technical Application
- Working Principle
The PSA oxygen generator adopts Pressure Swing Adsorption technology. Using zeolite molecular sieve to separate oxygen from ambient air, continuously supply high-purity oxygen without liquid oxygen or oxygen cylinder transportation.
- Core Parameter (20L Model)
Oxygen flow rate: 20 L/min
Oxygen concentration: 90%±3%
Continuous 24-hour non-stop operation
Stable outlet pressure, compatible with microbubble mixer, venturi and pipeline aeration system.
- Typical Application Scenarios
- Indoor Recirculating Aquaculture System (RAS)
- High density shrimp, tilapia, grouper, lobster farming
- Hatchery, fry breeding workshop
- Emergency oxygen supplementation for intensive fish ponds
- System Matching Advantage
Can be directly connected to RAS filtration, protein skimmer and disinfection units. Increase dissolved oxygen (DO) in aquaculture water, accelerate organic matter decomposition, inhibit anaerobic bacteria growth, improve water quality stability.
Economic Benefits Analysis
- Reduce mortality rate
Sufficient dissolved oxygen reduces fish and shrimp stress, avoids hypoxia outbreaks. Mortality can be reduced by 8%–15% in intensive farming.
- Accelerate growth cycle
Good oxygen environment promotes feed digestion. Feed conversion ratio (FCR) improves, shorten harvest cycle, realize more batches of cultivation within one year.
- Cut long-term oxygen cost
On-site air-to-oxygen production eliminates repeated purchases of oxygen cylinders or liquid oxygen. Compared with bottled oxygen, operating cost can be saved by 40%–65% annually.
- Support higher stocking density
Stable oxygen supply allows higher breeding density, maximizing output within the same pond area and increasing total annual revenue.
- Lower water exchange frequency
Optimized water oxygen level slows water quality deterioration, reduces water pumping and wastewater treatment expenditure.
