Oxygen Generator
Industrial Oxygen Generator
PSA oxygen generators use clean compressed air as feedstock and utilize zeolite molecular sieves to adsorb nitrogen and enrich oxygen under pressure. After the system is depressurized, the adsorbent desorbs impurities and regenerates. The two towers operate in an alternating cycle, controlled automatically by a PLC, producing oxygen with a purity of 93% ± 3%.
- Oxygen Output: 1–40 m³/h
- Oxygen Purity: 93% ± 3%
- Dew Point: –40°C
- Pressure: 0.01–0.6 MPa (Abooster is required for higher pressures)
- Type: Containerized, Skid-mounted
Oxygen Generator
The oxygen generator combines air compression, purification, and drying with high-efficiency oxygen production, offering a highly reliable all-in-one solution. Featuring a fully integrated design, the unit provides a continuous and stable supply of high-purity, pressure-adjustable oxygen. It directly addresses the aeration needs of high-density aquaculture, effectively increasing dissolved oxygen levels in the water to ensure the healthy growth and high growth efficiency of aquatic organisms.
- Oxygen Output: 10-80 L/min
- Oxygen Purity: 93% ± 3%
- Power: 0.8KW-5.8KW
- Output pressure: ≤0.4 MPa (Abooster is required for higher pressures)

What are the best oxygen diffusers for aquaculture?
The best oxygen diffusers for Recirculating Aquaculture Systems (RAS) are Micro-Pore Ceramic Plate Diffusers and Fine-Pore EPDM Disc Diffusers. For high-density systems requiring pure oxygen, Oxygen Cones (Speece Cones) or Venturi
Can pure oxygen kill fish?
Yes, pure oxygen can kill fish. While oxygen is the most critical element for aquatic life, excessive levels lead to two lethal conditions: Gas Bubble Disease
Aeration vs. Oxygen Generator: The Strategic Guide to Dissolved Oxygen in Modern Aquaculture
If there is one thing that keeps farm owners awake at night, it isn’t the price of feed or even market fluctuations. It’s the “silent
How do you calculate oxygen requirements in aquaculture?
In RAS aquaculture, you calculate oxygen requirements by turning every major oxygen “sink” into kg O₂ per hour, then sizing your oxygenation/aeration equipment so its actual oxygen
What size oxygen generator do I need for my fish farm?
To determine the size of the oxygen generator you need, focus on your daily feed rate. For a high-density Recirculating Aquaculture System (RAS), you require
The Cost of Running an Oxygen Generator for Fish Farming
Producing oxygen onsite costs between $0.05 and $0.18 per kilogram (kg). In a standard Recirculating Aquaculture System (RAS), electricity accounts for 80% to 90% of
