I filled a new 9L from 0-4500 with the CS4 and it took 4.5 hours I believe. I gave it a break in the middle and vented the moisture several times. Used the big gold filter and a one way valve as always.

Im going to sound dumb.. but what's a "60min" tank ..,? Like in volume , 40 cf ?, 9 liter,?I filled 4 60 minute SCBA tanks from empty with mine. I gave it plenty of breaks and purged the water about every 20 minutes. Each tank took me the better part of a day, but I did give it lots of breaks.
I believe it's 9 liters, but I get confused myself especially when they rate them in minutes or cubic feet.Im going to sound dumb.. but what's a "60min" tank ..,? Like in volume , 40 cf ?, 9 liter,?

Ya, I figured what's the he point in minutes .. like 60 minutes yoga breathing or 60 min panic stressed out breathing..lol. That make a big difference in a sizing ..lolThere are many words used to describe SCBA tanks, some of them aren't very accurate, like "minutes" (30/45/60). That term is typically used by firefighters who use them to breathe from. (But what isn't taken into account is the "state" of the breather; are they resting? Exerting themselves? Heavily exerting?)
Another misnomer is calling a SCBA tank a 45/66/88 cu ft tank. Again, air is compressible, so add more pressure, and you get more air volume. Not very accurate, yet many refer to their Great White tanks from topairguns as 97 cu ft.
A more accurate nomenclature is the water volume; this tells how big the tank actually is, since air is compressible, and the more pressure, the more air it holds.
The biggest SCBA tanks commonly sold are 550 cu in, or 9L water volume. Some also call these 97 cu ft (air volume), or 60 minute tanks. Joe Broncato clearly lists his tanks by size, take a gander at his site (also HIGHLY recommend buying from him; the tanks are not cheap knockoffs that are expired, but top-notch tanks that meet DOT transportation requirements).
Guppy - 114 cu (1.9L) in or <<20 cu ft (not very accurate, but close enough for gubmint work)>>
Tiger Shark - 410 (6.7L) cu in or <<74 cu ft>>
Great White - 550 cu in (9L) or <<97 cu ft>>
HTH
This should help. I posted this chart in a thread sometime ago.Im going to sound dumb.. but what's a "60min" tank ..,? Like in volume , 40 cf ?, 9 liter,?
Thanks, guys, for the replies they all do help! I know you say when filling and giving the pump a bunch of breaks. Can you explain your filling process a little more in detail?
