4. Setup
Follow these steps to assemble your vacuum chamber kit:
- Prepare the Vacuum Pump: Ensure the vacuum pump is placed on a stable, level surface. Check the oil level in the pump's sight glass. If low, add the provided vacuum pump oil until it reaches the 'MAX' mark.
- Connect the Gauge Assembly: Attach the vacuum gauge and valve assembly to the vacuum chamber lid. Ensure all threaded connections are tightened securely to prevent leaks.
- Attach the Vacuum Hose: Connect one end of the vacuum hose to the valve assembly on the chamber lid and the other end to the intake port of the vacuum pump. Ensure connections are tight.
- Place Silicone Pad: Position the silicone pad inside the vacuum chamber. This helps protect the chamber bottom and provides a stable surface for items being degassed.
- Position the Lid: Place the acrylic lid onto the vacuum chamber. Ensure it is centered and creates an even seal with the chamber's rim. The lid's weight and the vacuum itself will help create a tight seal.

5. Operating Instructions
This section outlines the procedure for degasifying materials using your VEVOR vacuum chamber kit.
- Prepare Material: Place the material to be degassed (e.g., resin, silicone) into a suitable container that fits inside the vacuum chamber. Ensure the container is not filled to the brim, as materials may expand under vacuum.
- Load Chamber: Carefully place the container with the material onto the silicone pad inside the vacuum chamber.
- Seal Chamber: Place the acrylic lid firmly onto the chamber, ensuring a good seal.
- Start Vacuum Pump: Close the valve on the gauge assembly. Plug in the vacuum pump and turn it on.
- Open Valve: Slowly open the valve on the gauge assembly to begin drawing a vacuum in the chamber. Observe the vacuum gauge for pressure reduction.
- Monitor Degassing: As the vacuum is drawn, air bubbles will rise and escape from your material. Monitor this process through the transparent lid. Materials may expand significantly before settling. Do not allow material to overflow.
- Maintain Vacuum: Once the desired vacuum level is reached (e.g., 5 Pa), close the valve on the gauge assembly and turn off the vacuum pump. The chamber should hold the vacuum.
- Release Vacuum: After the degasification process is complete (typically when bubbling stops), slowly open the air release valve on the gauge assembly to equalize the pressure inside the chamber. Do not open too quickly, as this can disturb the material.
- Remove Material: Once the pressure is equalized, remove the lid and retrieve your degassed material.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your vacuum kit.
- Vacuum Pump Oil Change: Change the vacuum pump oil regularly, especially after prolonged use or if the oil appears cloudy or discolored. Refer to the pump's specific instructions for oil change procedures.
- Clean Chamber: After each use, clean the inside of the vacuum chamber and the acrylic lid with a soft cloth and a mild, non-abrasive cleaner. Ensure no residue remains that could affect future seals.
- Inspect Seals: Periodically inspect the rubber gasket on the vacuum chamber lid for cracks, tears, or deformation. Replace if necessary to maintain an airtight seal.
- Check Hose: Examine the vacuum hose for any kinks, cracks, or damage. A damaged hose can lead to vacuum leaks.
- Store Properly: When not in use, store the vacuum kit in a clean, dry environment, protected from dust and extreme temperatures.
7. Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump runs but no vacuum is achieved. | Loose connections, damaged hose, lid not sealed, low oil. | Check all hose connections and valve positions. Ensure the lid is properly seated. Inspect the hose for damage. Check and refill pump oil. |
| Vacuum level drops quickly after pump is turned off. | Leak in the system (chamber, lid, hose, or connections). | Inspect the chamber gasket, lid, hose, and all fittings for leaks. Tighten connections. Replace damaged components. |
| Pump is excessively noisy or vibrates. | Low oil level, contaminated oil, pump malfunction. | Check oil level and add/change oil if necessary. If problem persists, contact support. |
| Material overflows in chamber. | Container too full, material expands too rapidly. | Use a larger container or fill less. Slowly open the vacuum valve to control pressure drop. |
