CONVUM EC1 Vacuum Ejector｜Power-Free, Energy-Saving & Fast Blow-Off

• Power-Free, Energy-Saving: Air-driven only; once the target vacuum is reached, air supply stops automatically—no electric control required.
• Auto Hold with Check Valve: A built-in check valve retains vacuum on tight workpieces and auto-restarts air supply when vacuum drops below the threshold.
• Fast Blow-Off: An internal blow-off reservoir vents to the vacuum port at shut-off for rapid release, helping shorten cycle time.
• Direct Cup Mounting: Suction cups can be mounted directly on the body—less tubing loss, simpler installation, smaller footprint.
• Clean Air Ready: Works best with clean, dry, oil-free air and upstream filtration for stability and long service life.
• Flexible Sizing: Select the nozzle size by leakage rate, cup size, and required cycle time.
• Applications: Power-restricted cells, energy-saving retrofits, fast pick-and-place stations, sorting/loading modules, compact end-of-arm tooling.

Q1: Does EC1 need electrical power?
A: No. It's fully air-driven; after reaching the set vacuum, it auto-stops air supply.

Q2: How do I set the shut-off vacuum level?
A: A factory setting is provided. For fine adjustment, use the set screw/adjuster on the unit (range per model—see datasheet).

Q3: How are vacuum hold and restart handled?
A: The check valve holds vacuum after stop; when vacuum falls below the threshold, supply auto-resumes.

Q4: How is fast blow-off achieved?
A: At shut-off, the internal blow-off tank vents to the vacuum port for rapid release; an external blow-off valve can be added if needed.

Q5: Can a suction cup mount directly to EC1?
A: Yes. Direct mounting reduces line losses and shortens cycle time, while simplifying assembly.

Q6: Can I add gauges or sensors?
A: Yes—add a vacuum gauge/mechanical switch, or (if power is available) an electronic vacuum sensor for monitoring without changing EC1's power-free nature.

Q7: What air quality/filtration is recommended?
A: Clean, dry, oil-free compressed air with upstream filtration (typ. 5–40 μm, per plant standard) for stable performance and longevity.

Q8: How do I choose the nozzle size/model?
A: Match to leakage, cup size, and cycle time. Larger leakage or faster cycles → choose a higher-flow nozzle.

Q9: How noisy is it?
A: There is exhaust noise during generation; after auto-stop, noise drops. A muffler can be fitted to the exhaust if required.

Q10: What maintenance is needed?
A: Periodically check filters/lines, fitting seals, and cup lips. With no electronics and a simple mechanism, maintenance is minimal.
