From meeting specific purity levels to integrating with your existing infrastructure, we provide custom-built solutions that align seamlessly with your project objectives.



FAQ
| 1. What is the difference between a VPSA oxygen generator and a PSA oxygen generator? |
- A PSA oxygen generator is suitable for scenarios with an oxygen demand of below 300 cubic meters per hour (m³/h). It features simplicity, convenience, and portability.
- A VPSA oxygen generator is designed for demands of over 300 m³/h. A key advantage is that the higher the gas output, the lower the energy consumption.
|
| 2. What is the difference between a fish pond aerator and a fish pond oxygen generator? |
- A fish pond aerator is a self-contained air pump that mixes the 21% oxygen (standard air oxygen content) in ambient air into the water.
- A fish pond oxygen generator works by producing oxygen with a purity of 90%, which is then dissolved in the water.
- When selecting between the two, merchants should consider factors such as fry species, required oxygenation rate (to optimize the production cycle), and the total size of the fish pond.
|
| 3. What is the oxygen purity of a PSA oxygen generator? |
- The oxygen purity of a standard PSA oxygen generator typically ranges from 90% to 93%.
- Our company's PSA oxygen generators can achieve higher purities: 95%, 98%, and even up to 99%+.
|
| 4. What should be noted when using an oxygen generator for ozone production? |
| When an oxygen generator is used to support ozone production, the core requirement is to select a unit with stable gas output and purity. This prevents inconsistencies in ozone concentration and production that would otherwise result from unstable oxygen supply. |
Maintenance of PSA Oxygen Generator
The daily maintenance of the oxygen generator is relatively straightforward, as outlined below:
- Air Compressor Maintenance: Conduct regular maintenance on the air compressor. The air filter and oil should be replaced by the manufacturer at specified intervals in accordance with the operation manual.
- Dryer Maintenance:
- Regularly check the refrigerant pressure of the dryer and ensure timely maintenance if anomalies are detected.
- Clean the heat sink with compressed air daily.
- Replace the filter element regularly; its normal service life is 8000 hours, though the actual replacement time should be determined based on specific operating conditions and pressure differences.
- Air Storage Tank: Open the drain valve of the air storage tank once daily to drain condensed water from the air system.
- Automatic Drain Valve Check: Inspect the automatic drain valve daily to prevent clogging (which would cause drainage failure). If clogging occurs:
- Slightly open the manual valve first.
- Close the automatic drain valve.
- Remove the automatic drain valve, disassemble it, and clean it with soapy water.
- Oxygen Generator Core Check: For the oxygen generator itself, focus on checking the working pressure of the adsorption tower, and record key parameters including oxygen purity and flow rate.
