I think I have seen a few peeps here using a dolphin first stage. Does anyone know how low the IP can be adjusted on one?

I donīt know about the 1st generation piston 1st stages.
Iīm using the 2nd generation Draeger diaphragm 1st stages and they can reach up to 20 bar.
Make sure your IP hoses can handle that.
