C-KLR ZEPHYR Dual-Function Vacuum & Pressure Claw Pump - Model Selection (80 / 140)

One Pump, Two Gas Circuits

C-KLR ZEPHYR is a single-body, dual-function dry unit from the Elmo Rietschle ZEPHYR family. Using a patented composite claw rotor, one pump simultaneously outputs vacuum (negative pressure) and clean positive pressure. The range has two models - C-KLR ZEPHYR 80 and 140 - covering 80-140 m3/h, with vacuum up to -0.6 bar(g) and pressure up to +1.0 bar(g). The key to sizing is matching the combined demand of both the vacuum and pressure loads, not a single flow figure.

How to Choose Between the Two Models

· C-KLR ZEPHYR 80: 50Hz suction 94 m3/h / pressure 85 m3/h, 4.0 kW, 120 kg, both vacuum and pressure flanges G 1 1/4 - fits compact packaging and desktop electronics pick-and-blow lines.

· C-KLR ZEPHYR 140: 50Hz suction 117.8 m3/h / pressure 120 m3/h, 5.5 kW, 160 kg, both flanges G 1 1/2 - fits central air supply and multi-station printing/binding lines.

· Both models feature IE3 high-efficiency motors and IP55 protection, integrated active air cooling plus an exhaust after-cooler for 24/7 dual-duty operation.

Key Features

· Dual-loop output: one body generates vacuum and clean positive pressure, replacing a vacuum pump plus a booster/compressor.

· Patented composite claw rotor: contact-free internal compression, both chambers oil-free and contamination-free.

· Exhaust after-cooler: positive-pressure discharge temperature close to ambient, no thermal impact downstream.

· Dual safety protection: check valve against vacuum backflow, relief valve against overpressure - independent per loop.

· Synchronized VFD control: one drive tunes both vacuum and pressure output for automated process control.

Typical Applications

· Packaging: vacuum film pickup/box opening + positive-pressure bottle separation blowing on one line.

· Electronics automation: PCB vacuum clamping + positive-pressure dust blow-off in the same step.

· Printing/post-press: paper vacuum feeding + air separation, as a press central air source.

FAQ

Q: Is the only difference flow rate? A: No - also motor power (4.0 vs 5.5 kW), flange size (G1 1/4 vs G1 1/2) and weight. Choose 140 for higher air demand or larger piping.

Q: Can vacuum and pressure be adjusted independently? A: They are VFD-synchronized; external valve sets can trim each load, but neither loop can be fully shut off to run alone.

Q: OEM part or replacement? A: C-KLR ZEPHYR is a factory-direct complete unit, not trader-resold; specs per this table.

Conclusion

C-KLR ZEPHYR 80/140 covers the combined vacuum + pressure demand of compact automation lines. Pick 80 for lighter duty, 140 for larger or central supply - both share oil-free operation, IE3/IP55 rating and integrated cooling. Factory-direct; contact us for sizing by duty.
