Nitrogen Generation for Laser Cutting

A lean and efficient shop has become vital to the success of a laser cutter. Nothing can provide you with more cost savings than to generate your own N2 gas. On Site Gas nitrogen generator systems are in dozens of laser cutting shops, producing from 95 to 99.995% purity with output pressures of up to several hundred PSI. Some of the questions we ask before we size a nitrogen generation system are: Who manufactured your laser(s) and what is the wattage/model? What type of materials are you cutting? What is the thickest metal you cut? At what pressure do you cut your thickest metal? What size nozzle do you use to cut that thickest metal? Armed with that information, our nitrogen generators can save you hundreds of thousands of dollars over bulk N2.
