Compact PSA Oxygen Generator for live fish tanks. Stable high-purity oxygen supply helps maintain freshness, reduce losses, and support 24/7 tank operation.
High-density tanks, summer temperature changes, and unmanned night operation can increase oxygen shortage risks.
Oxygen deficiency in crowded tanks may increase die-off risk and operating losses.
Insufficient oxygen can contribute to odors, murky water, and poor tank conditions.
Stressed fish can show rapid decline in quality, affecting customer satisfaction.
Chiller controls temperature, air pump supports circulation, and PSA adds concentrated oxygen. The system connects to existing air hose and diffuser lines with minimal installation work.
Chiller + Air Pump + PSA Oxygen Generator
Temperature · Circulation · Pure O₂ integrated for stable live tank management.
A PSA generator supplies higher-concentration oxygen than a standard air pump alone.
| Item | Air Pump Only | After Adding PSA Oxygen Generator |
|---|---|---|
| Oxygen Concentration Supplied | ~21% air | 90% pure oxygen |
| Live Fish Mortality Rate | 10–20% at high density | Under 3% |
| Tank Capacity | Baseline 100% | 200–300% |
| Water Quality Maintenance | Frequent maintenance required | Stable for 24 hours |
