Fire extinguishers are first-line life-safety devices — their pressure integrity directly determines whether they work when disaster strikes. Even the tiniest leak in a cylinder, valve assembly, or seal can cause gradual pressure loss, rendering the extinguisher useless in an emergency. That’s why leading fire safety manufacturers rely on helium leak detection as the final quality gate before products ship.
Traditional water bath and pressure decay methods miss micro-leaks and produce high false-reject rates. Helium mass spectrometer leak testing for fire extinguishers detects leaks down to 1×10⁻⁹ Pa·m³/s with absolute accuracy, guaranteeing every cylinder, valve, and complete extinguisher assembly meets international fire safety standards (EN 3, UL, NFPA).
At Daxin Vacuum, our helium leak detection systems for fire extinguisher production lines deliver high-throughput, fully automated testing for CO₂, dry chemical, and clean agent extinguishers. With custom vacuum chamber designs, fast cycle times, and integrated helium recovery (≥95% efficiency), we help fire equipment manufacturers boost yield, reduce helium costs, and achieve 100% leak-tight quality assurance.
For fire safety manufacturers, helium leak testing isn’t just a quality control step — it’s a commitment to protecting lives and property.
