2 bottles at a time flow rate of 1500 cubic inches per minute(that is a standard for scba not to be exceeded), revolve air system, no down time, while 2 are filling 2 more are hooked up and waiting to be filled.
**** 3 min per bottle flow rate, 2 @ a time = min and a half and not all bottles are completly empty when they need refilling, thats how the math works out.
yes it has a cascade system on the truck, capable of filling 60 bottles per hour, carries 46 spare cylinders, and will housed at sta 1 until plymo-vent system is upgraded at sta 3
