They were cheaper for a better purity and flow rate than Parker. It’s overkill for most of our N2 needs, but it’s cheaper to supply 99.9995% to everything than to have both low and high purity N2 lines running around the facility. OnSiteGas sales team was great. We did have one issue during install. We used a SS flex hose to supply compressed air to the N2 Gen. This caused the system to “ring” every time it generated N2. I recommend using the really simple rubber hose onsitegas provides to connect from CDA to N2Gen to minimize vibration and resulting noise. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The maintenance is super simple. Just a few compressed air filters on a regular schedule. Approx $500 a year. As long as the N2Gen has compressed air, it pumps out nitrogen. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>This was our sales rep.
