Full Model Interpretation

2. Key Technical Specifications

3. Kernvorteile
4. Significantly Increased Flow: 240 L/min (ANR), 2.4 times the old IRV2000 (100 L/min), meeting higher vacuum demands
5. Flexible & Easy Installation: Single-side piping + bottom bracket, space-saving, suitable for various mounting layouts
6. Simple & Efficient Maintenance: Gauge/digital switch secured with clips, easy to install/remove; mounting direction adjustable (standard piping)
7. High-Precision Control: Resolution ≤ 0.13 kPa, stable vacuum for precision applications
8. Lightweight Design: 20% weight reduction, lower equipment load
9. RoHS Compliant: Meets environmental standards for industrial use
10. Funktionsprinzip

The IRV series uses a balanced diaphragm structure. Pressure is set by balancing spring force and SET-side pressure:

1. Turn knob clockwise → spring compresses → opens VAC to SET path → vacuum increases on SET side
2. When SET-side vacuum is below setpoint → diaphragm unbalances → closes atmosphere intake → opens VAC path → vacuum recovers
3. When SET-side vacuum exceeds setpoint → diaphragm rises → opens atmosphere intake → vacuum lowers to setpoint

The digital pressure switch (D1 type) monitors vacuum in real time and provides an NPN output for automation feedback and alarm.

5. Typische Anwendungen
6. Semiconductor Manufacturing: Vacuum adsorption for wafer handling, chip packaging
7. Electronic Assembly: Vacuum fixing for SMT mounters, PCB transfer
8. Automation Lines: Precision vacuum control for robot end-effectors, vacuum chucks
9. Packaging Industry: Vacuum adjustment for vacuum packaging machines to ensure sealing
10. Medical Equipment: Vacuum systems for laboratory analyzers and medical instruments
11. Printing Machinery: Vacuum adsorption for paper feeding and plate fixing
12. Installation & Usage Guidelines
13. Mounting Direction: Vertical installation recommended to avoid gauge zero shift (inversion affects accuracy)
14. Piping: Use φ10mm tubing; ensure clean, leak-free lines to minimize pressure loss
15. Pressure Adjustment: Turn knob slowly to avoid sudden vacuum changes
16. Wartung: Regularly check fitting sealing; clean gauge/digital switch ports
17. Digital Switch Setting: Set upper/lower limits according to application for stable control
18. Ersatz & Kompatibilität

Standard Replacements: IRV20-C10B (without bracket & switch), IRV20A-C10B (single-side standard)

Upgraded Versions: IRV20-C10BD (with digital switch), IRV20-C10BG (with gauge)

Cross-Brand Alternatives: Interchangeable with FESTO VREG series, CKD VEX series (verify port specs)
