2. Safety Information

WARNING: This carbon fiber air tank operates at extremely high pressures. Improper handling or use can result in serious injury or death. Always adhere to the following safety guidelines:

  • Do not fill if the cylinder has visual damage (e.g., cracks, dents, deep scratches, delamination of carbon fiber).
  • Always inspect the tank for damage before each use.
  • Ensure all connections are secure and leak-free before pressurizing.
  • Never exceed the maximum working pressure of 4500 PSI (300 BAR / 30 MPa).
  • Only use approved filling equipment and follow the instructions provided with your filling station or compressor.
  • Keep the tank away from direct heat sources, open flames, and corrosive chemicals.
  • Do not modify the tank or its valve in any way.
  • Always wear appropriate personal protective equipment (PPE), such as eye protection, when handling or filling the tank.
  • Ensure proper ventilation when filling to avoid accumulation of compressed air.
  • The tank is CE certified but not DOT approved. Be aware of local regulations regarding high-pressure cylinders.
  • Adhere to the re-test period of 3 years and the service life of 15 years. Do not use the tank beyond these limits without proper re-certification.

3. Product Components

The TUXING 3L Carbon Fiber Air Tank system typically includes the following components:

  • 3L Carbon Fiber Air Tank: The main pressure vessel.
  • Dual Gauge Valve (Filling Station): This assembly connects to the tank and features two pressure gauges, an on/off valve, a release valve, and a high-pressure hose with quick connectors.
  • High-Pressure Hose: Connects the filling station to your device (e.g., PCP air rifle).

4. Setup and Filling Instructions

Follow these steps to set up your TUXING 3L Carbon Fiber Air Tank and prepare it for filling or use:

  1. Inspect the Tank: Before each use, visually inspect the carbon fiber tank for any signs of damage, such as cracks, deep scratches, or delamination. Do not use a damaged tank.
  2. Connect the Valve: Carefully screw the dual gauge valve assembly onto the M18x1.5 cylinder neck thread of the air tank. Ensure it is hand-tightened securely. Do not overtighten.
  3. Connect to Compressor/Filling Source: If filling the tank, connect the appropriate high-pressure hose from your air compressor or larger storage tank to the input port of the dual gauge valve. Ensure all connections are secure.
  4. Connect to Device (if applicable): If you are using the tank to fill a PCP air rifle or other device, connect the output hose from the dual gauge valve to your device's filling port.

Filling Procedure:

  1. Ensure the release valve on the dual gauge valve is closed.
  2. Slowly open the main valve on the air tank.
  3. Begin filling from your compressor or larger tank. Monitor the pressure on the tank gauge.
  4. Fill the tank gradually to avoid overheating. Do not exceed 4500 PSI (300 BAR).
  5. Once the desired pressure is reached, close the main valve on the air tank and then turn off your compressor/filling source.
  6. Slowly open the release valve on the dual gauge valve to vent any residual pressure in the hose before disconnecting.

5. Operating Instructions

To use the TUXING 3L Carbon Fiber Air Tank to fill a device (e.g., PCP air rifle):

  1. Ensure the air tank is filled to the desired pressure (up to 4500 PSI).
  2. Connect the high-pressure hose from the dual gauge valve to your device's filling port. Ensure the connection is secure.
  3. Ensure the release valve on the dual gauge valve is closed.
  4. Slowly open the main valve on the air tank.
  5. Slowly open the on/off valve on the dual gauge valve to allow air to flow into your device. Monitor the pressure on both gauges: one for the tank pressure, and the other for the inline pressure being delivered to your device.
  6. Once your device is filled to its recommended pressure, close the on/off valve on the dual gauge valve.
  7. Close the main valve on the air tank.
  8. Slowly open the release valve on the dual gauge valve to vent any residual pressure in the hose before disconnecting from your device.

6. Maintenance

Proper maintenance ensures the longevity and safe operation of your TUXING air tank.

  • Regular Inspection: Routinely inspect the tank for any physical damage, including cracks, dents, or fraying of the carbon fiber wrap. Check the valve for leaks or damage.
  • Cleaning: Clean the exterior of the tank with a damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the epoxy coating or carbon fiber.
  • Storage: Store the tank in a cool, dry place, away from direct sunlight, extreme temperatures, and corrosive substances. Ensure the tank is partially charged (e.g., 500-1000 PSI) for long-term storage, but never store it completely empty or fully pressurized for extended periods.
  • Re-Test Period: The tank requires a hydrostatic re-test every 3 years from the date of manufacture or last test. This is crucial for safety and compliance.
  • Service Life: The design service life of the tank is 15 years. Do not use the tank beyond this period, even if it passes hydrostatic tests, as material fatigue can occur.
  • Valve Maintenance: Periodically check the valve O-rings and seals for wear. Replace them if any signs of damage or leakage are observed.

7. Troubleshooting

If you encounter issues with your TUXING air tank, consider the following:

  • Air Leakage:
    • Check all connections (tank to valve, hose to valve, hose to device) for tightness.
    • Inspect O-rings and seals for damage or improper seating. Replace if necessary.
    • Listen for hissing sounds or use a soapy water solution to identify the exact location of the leak.
  • Tank Not Filling:
    • Ensure the main tank valve and any valves on your compressor/filling source are fully open.
    • Check the pressure output of your compressor/filling source.
    • Verify that the hose and connectors are not blocked.
  • Device Not Filling from Tank:
    • Ensure the tank has sufficient pressure.
    • Verify the main tank valve and the on/off valve on the dual gauge valve are open.
    • Check the connection to your device for proper seating and that its internal valve is open.

If you cannot resolve an issue, contact customer support or a qualified technician.
