Where do you fill these tanks
Is this tank manufactured in the USA ?
Can this tank be filled with a hand pump
Is it possible, yes......would you physically want to attempt it, not likely. The amount of time it would take to pump that kind of volume would be crazy
How do check the psi in the tank?
You would plug a test plug into the end of the hose and open the valve. That will fill the line to the max pressure available in the cylinder and that pressure will display on the gauge.
What is needed to fill this tank with a shoebox compressor?
Nothing. The quick disconnect on the hose will connect to the output on the shoebox.
I received the tank today but the pressure gauge on the valve is losing. You can move the gauge back and forth, left and right. Is that normal?
Yes, that is normal.
Sir, concerning the tank below, how can I be assured it is not more than a year old? Air Venturi Carbon Fiber Charging Station, 4500 psi, 98 cu ft
The date of manufacture is printed on the tank's label.
Will the hose supplied connect to my discovery , Maximus and future marauder ? On the 2000 psi guns - how many charges can I expect ?
Fill calc: https://sye.dk/airgun/index.php
Yes it will connect. With a full 4500 psi in the tank and filling to just 2000 psi, you'd be looking at well over 100 full fills. The Marauder would get about 50-60 full fills.
Is there a regulator I can buy for this tank? Like the one the 74cu ft tank came with.
how many cubic inches is this tank ? is it more than 550CI ?
You'd have to do the math to figure it out but I'd imagine 550CI is very close. If you want max size I'm not sure they make a bigger tank of reasonable size. Or I should say the only larger ones I've seen were much much larger.
98 cubic feet . 4500 psi.
Can this be filled directly from a shoebox or do in need another fitting to go with it to fill from a shoebox
A shoebox should fill it if you get the 4500psi model. It will take a bit of time to fill from empty though.
What else do you need to fill this tank from a shoebox compressor
Fitting wise you should be good, plug straight into the Shoebox. I'd be concerned about water tho, so I made a dryer for mine. I saw a pix of a pcp where the guy used normal/wet air for a year or so and it was an omg disaster inside. Maybe he had an ocean breeze or something but whatever the case I'm paranoid now.
