Pfeiffer 3G Ion Source Filament – Frequently Asked Questions (FAQ)

1. How often should Pfeiffer leak detector filaments be replaced?

Typical lifespan: 6-12 months, depending on usage. Replace if sensitivity drops or errors occur.

2. How do I know if my filament needs replacement?

Common signs:

Unstable ion current

Reduced leak detection sensitivity

Error messages (e.g., "Filament Failure")

3. Why choose yttria-iridium filaments over standard ones?

Yttria coating enhances oxidation resistance and extends filament life under high temperatures.

4. Are aftermarket filaments reliable?

Our filaments meet OEM standards at a lower cost, ensuring performance without compromise.

5. Are ASM340W and ASM340D filaments interchangeable?

Some models are compatible, but always verify with your detector’s specifications.

6. Is recalibration needed after filament replacement?

Yes, recalibration ensures optimal detection accuracy.

7. Can I replace the filament myself?

Recommended for trained technicians to avoid ion source damage.

8. How much does filament repair cost vs. full replacement?

Filament repair can save over 50% compared to a new ion source assembly.

9. How can I extend my Pfeiffer filament’s lifespan?

Minimize frequent power cycling

Maintain a clean vacuum system
