I thought Meridiano too was membrane but someone a few months said they weren't - I never went back down to ask/ Aldora is membrane, i didn't look real close at the guy next to them.
I have seen the liquid O2 tanks at Meridiano in the non scuba bay....
Meridiano 87 uses O2 blending per their website and also provides industrial and medical gasses to the island. The other scuba fill, commercial, suppliers AICO and Lin-Mar use membrane systems. For years Meridiano was the only commercial filler for Nitrox but that is no longer the case. The Greek gentleman who runs AICO came over from the mainland a couple years back and started a fill station across from Casa Mission. I not sure when Lin-Mar began doing nitrox but they also use a membrane system as I picked up an O2 sensor for their control panel sensor in a couple months back. AICO is fanatic about fill levels, every tank leaving their facility gets a pressure check and if low it gets a leak check, typical fills are 3100 PSI
