Zero Air Generators & Compressors

Zero Air is one of the most popular gas sources used in analytical laboratories. Proton OnSite generators produce clean zero-grade air utilizing catalytic reactor technology and PSA technology which will meet different requirements for various labs.

Using an on-site gas generator not only saves tremendous valuable bench-top space, but also optimizes the operation-no more waiting for delivery, switching empty units, or recalibrating new cylinders- plug in, and it is all set. 

PSA Technology

PSA (Pressure swing adsorption) technology separates nitrogen molecules from the other gas molecules by the carbon molecular sieves (CMS). Alternating between both CMS columns, firstly O2, moisture, hydrocarbons, CO2, and other “contaminants” are absorbed, allowing the nitrogen to flow into an accumulation tank. From the accumulation tank the nitrogen is pressurized and delivered to the generator outlet for use.
