FAQ Guide
Product Name: Vacuum Generator (Ejector Type)
Model: VYF43M-50M
Manufacturer: PISCO (or compatible brands)
Common Use: SMT pick-and-place, robotic vacuum handling, packaging
automation
1. What is the function of the VYF43M-50M?
The VYF43M-50M is a pneumatic vacuum generator, also called an
ejector. It creates vacuum pressure using compressed air,
eliminating the need for electric pumps. It’s widely used in
compact, high-speed applications where stable suction is needed.
2. What are its key features?
Compact & lightweight – easy to install in space-limited areas
50 µm built-in filter – protects internal flow path from dust
No moving parts – low maintenance, long life
Instant vacuum generation – fast response, suitable for high-speed
pick-up
3. What accessories are commonly used with it?
VAF-50M: Replacement filter element
Suction cups (VP10, VP20, etc.)
PU tubing (φ4 or φ6)
Silencer (VRL series)
Vacuum sensor or switch (PSA series)
Check valve / Vacuum regulator
4. How often should the filter be replaced?
Check every 2–4 weeks depending on operating environment
Replace the filter (VAF-50M) if you see:
Suction power decrease
Longer vacuum build-up time
Visible dust buildup inside the ejector
5. What problems occur if the generator fails?
Loss of vacuum → component pickup errors
Contaminated filter → reduced suction and pressure drops
Excessive noise → muffler may be missing or clogged
Air leakage → check tubing and O-rings
6. How is VYF43M-50M installed and maintained?
Installation:
1. Connect compressed air to the inlet
2. Connect the vacuum port to the suction cup
3. Secure the exhaust port (add silencer if needed)
4. Verify all tubing is secure and leak-free
Maintenance:
Periodically clean the internal filter
Replace the VAF-50M if clogged
Inspect fittings and tubing for cracks or wear
7. Summary
The VYF43M-50M vacuum generator is an efficient, compact, and
maintenance-friendly ejector ideal for automation systems. Proper
filter maintenance and vacuum line integrity are key to ensuring
stable performance and minimizing machine downtime.
