Krypton 4500, cs4 or e5-k2

Just my opinion but throw the krypton right out the window. It’s a rebranded tuxing twin cylinder. Not to say that is horrible but a tuxing can be had for like half the price. I have no experience with the tuxings. I understand they are very loud but some have had good luck. I personally think gx pumps have proven themselves more rock solid and would be my choice. Which GX ?? To me that would depend on how often I was filling that 6.8L bottle. If that will be done a lot I would go with the e5k1. Will do it faster and is designed to be primarily used to fill larger scba bottles. The cs4 will do it but run times will be longer. The cs4 design seems to lean more toward filling guns direct with occasional large scba fills.

Thank you for the reply. I’m leaning towards the gx cs4I, 80% of the time it will fill guns, I will use it to periodically fill the 6.8L bottle. From my research, I think it should do fine. I’m on my 3rd umarex ready air.

Yeah probably the good choice for that. Especially after the initial fill of the scba you will only be topping it off.
