Intersting that they are filled to 300 bar, been a little bit of chat about the pressures changing. good idea having regs built in stops the idiots using circa 1970's regs rate for 120 bar on them
They have a fully adjustable pressure guage to allow you to set your flow rate
one wheel to turn the gas on and off and a second wheel to adjust pressure/flow
and you can fit your hoses straight on, standard 3/8 fittings, no need to buy an additional snap on adaptor
the Air Products Integra appear to only have an on and off hand wheel, and seem to be a fixed flow rate and you have to purchase and attach additional snap on connectors (economisers) if you want to change the flow
sounds a bit fiddly to me, I would rather just reach up and turn a wheel dependant on the job i'm doing
