Z4 laser gas generator

Zero Air Generator for Laser Protection

The Z4 zero air generator perform in 24/7 production process worldwide with utmost reliability. Even under the most challenging environments Z4s guarantee frictionless industrial use for different applications (example: high power UV-lasers (>300 nm)). The Generator produces a continuous flow of hydrocarbon-free air. The flow is controlled stable. All Generators reduce the total quantity of hydrocarbons to less than 0,01 ppm, establishing a stable flow for your application. Zero-air produced in this way replaces existing stocks of synthetic air stored in high pressure bottles.

Zero Air generators are designed specifically to supply clean, dry, hydrocarbon-free air to be used for several applications.

LNI Swissgas recognizes the importance of having a safe, reliable and cost effective supply of high-purity Zero Air.

In addition providing flexibility to add or remove modules as your application requirements evolve over time.


  • LED Indicators
