A lean and efficient shop has become vital to success. Nothing can provide you with more cost savings than generating your own N2. On Site Gas Systems are in a number of laser-cutting shops for beam purge or assist gases. Producing N2 99% to 99.9995% purity with output pressures up to several hundred PSI. Oxygen systems are also available.
On Site Gas will work with you to determine the most economical system for your current and future needs based on the laser manufacturer, nozzle size, material type and thickness. Armed with this information, we can save you 60-70% over your traditional method of purchasing N2.
Compressed air enters one of two sieve beds (filled with carbon molecular sieve-CMS). While the smaller oxygen molecules are adsorbed by the CMS, the larger nitrogen molecules pass through and are stored. Upon saturation, the first sieve bed releases the oxygen, while the second sieve bed starts the process over again.
We are specialist suppliers of on-site nitrogen and oxygen generators. We offer leasing and rental options so please get in touch to see how we can tailor a system to suit your requirements.

Nitrogen is used to ensure a clean cut in the laser cutting process and purities of 99.99% are typical in both mild steel and stainless steel applications.
Our PSA (pressure swing adsorption) nitrogen generators are the most common technology used for this application.
Generator costs vary. We work with you to properly size the system to meet your purity, flow rate, and pressure requirements. Once this is done, we can make a formal price quote, and calculate your payback time. Please get in contact with us and we can provide you with a personalised quote.
