SP-A02 Adjustable Helium Spray Gun - Pfeiffer Adixen Replacement

Why Choose SP-A02 Adjustable Helium Spray Gun

The SP-A02 adjustable helium spray gun is specifically developed for Pfeiffer Adixen helium mass spectrometer leak detectors, offering direct replacement for OEM part numbers 2000046756/109951. Featuring a knob throttling structure with 0.4mm capillary, the SP-A02 allows precise setting of constant output flow, adapting to workpieces ranging from large to micro leaks. The 304 stainless steel gun head combined with injection-molded housing provides excellent corrosion resistance and durability, while the wide temperature range of -10C to 60C ensures stable operation in diverse working conditions.

Frequently Asked Questions

Q: Can SP-A02 directly replace Pfeiffer OEM 2000046756?

A: Yes, the SP-A02 uses a standard 6mm quick-connect interface that is fully compatible with Pfeiffer OEM spray gun interfaces. Flow adjustment range covers OEM spray gun use cases, no modifications needed.

Q: How to choose between SP-A01 and SP-A02?

A: For ultimate constant flow, strict helium background control, micro-leak high-precision detection, choose SP-A01. For workpieces with large leak rate differences, frequent flow switching needs, or environments with temperature fluctuations, choose SP-A02.

Q: Will flow change if pressure changes after knob adjustment?

A: Compared to ordinary press-type spray guns, it has stronger anti-disturbance capability, but severe pressure fluctuations may still cause slight changes. For high-precision micro-leak detection, we recommend the SP-A01 constant flow model.

Conclusion

The SP-A02 adjustable helium spray gun is an excellent choice to replace Pfeiffer Adixen OEM 2000046756/109951. With knob continuous flow adjustment, wide temperature operation, 304 stainless steel corrosion-resistant body, and 136g lightweight design, it suits both high-volume production line testing and flexible field maintenance use.
