CONVUM HDV Vacuum Ejector | -98.6kPa High Vacuum for Chambers

• Higher Vacuum Level: Reaches up to −98.6 kPa (actual performance depends on supply pressure, plumbing, and leakage).
• Optimized for Evacuation: Ideal for container degassing, vacuum chamber pre-evacuation, and leak/airtightness test setups.
• Stable Long-Run Output: Maintains vacuum level during continuous operation for consistent processes.
• Compact & Lightweight: Easy to integrate into modules or downstream evacuation stations.
• High System Compatibility: Works with CONVUM pads, valves, and vacuum sensors to form a complete system.
• Applications: Chamber/fixture evacuation, container degassing/defoaming, lab pre-evac, leak test benches, packaging/forming pre-vac.

Q1: How is HDV different from standard ejectors?
A: HDV reaches about −98.6 kPa, making it better suited to chambers/containers and leak-testing where higher vacuum is required.

Q2: Will it always achieve −98.6 kPa?
A: That's a nominal limit. Real-world results depend on air supply, line length/leaks, filtration, and environment—verify on site.

Q3: Can I use it for general gripping?
A: Yes, but very high vacuum may deform thin or flexible parts. Consider lowering the set level or using a standard ejector for such cases.

Q4: How do I size/select a model?
A: Match chamber/container volume, target evacuation time (cycle time), and allowable leakage. Larger volumes or shorter times → higher-flow models.

Q5: What air quality is recommended?
A: Clean, dry, oil-free air with upstream filtration (typ. 5–40 μm) to maintain efficiency and service life.

Q6: Can it integrate with other CONVUM components?
A: Yes—combine with CONVUM valves, pads, and vacuum switches/sensors for full monitoring and control.

Q7: What about noise and maintenance?
A: Normal exhaust noise occurs during evacuation; add a muffler if needed. Maintain by cleaning/replacing filters and checking lines/fittings.

Q8: Troubleshooting slow evacuation?
A: Check supply pressure, line diameter/length, leaks, and filter clogging; if necessary, increase nozzle size/flow or shorten plumbing.
