In-line Regulator Step DownMany customers want to use the Avi with existing aircraft oxygen systems to increase endurance, but many of these OEM systems output between 70 100PSI. The Aithre Avi pulse demand systems require an input pressure of 50 60PSI, so plugging the AVI directly into this higher pressure source will break the AVI and will cause oxygen leakage. This Mountain High Aithre regulator will step down the pressure from your existing OEM oxygen system from 70 100 PSI

Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly. Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration. Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…

Thought the assembly was metal, it’s some kind of PVC.
