View Full Version : A few questions regarding scuba tanks and misc. tank accessories

alright guys, most of you know that my friend has a 10-man diablo field at his house. Now our only problem is filling our own tanks. Thanks to mr. Drefish, I was linked to a helpful website. Here's what I found so far.


I'm wandering how many of these I'll need for a whole weekend of play for about 5-8 guys. Also, will the only other thing I need be a simple fill station and how do I install the fill station onto the scuba. Should I let an airsmith handle this. One more thing.... where in the heck will I have to take these scuba tanks to get filled?

80 cu ft will run you for about 2 people full day at best depending on marker. Also these need to be filled at a scuba shop. Also these only hold 3000 psi so as the day dwindles down exspect 1500 psi fills. Your best bet is to fond a place that does welding gases. Then you can get a 444 cu ft tank that is 4500 and run 25+ people per day. Also instead of you dealing with filling it they will usually pick it up and drop it off. They also offer Nitrogen in a near pure form which is even better than HPA. If I remember right it's $50 per fill....oh and Nitrogen and some HPA from welding places run ashigh as 6K. You can get a nitrogen fill station for about $300 or make your own none regulated and use your tank gauge or an inline gauge. I have pics if you need more info.......but first locate a tank!

I was going to suggest the same thing about looking into a high pressure bulk tank from a welding/industrial gas supplier.

If you go with the scuba's then I would think probably 4-6 tanks ran in series would do good....???

Would do OK, but limit you to 3000psi max!

alright guys, this is helping. Yeah, I definitey need to fill 4500 tanks so I guess I'll have to look for a bulk tank some where else. If you guys see any on the horizon, holla at me.

Those tanks are over $1000K new.......easier to lease one!

i use two scuba tanks. when filling everybody (5-8) my tanks last only a weekend. like timber says you will not be getting full fills but it is enough for a game then refill. depends on your style of play. i normaly dont fire more than 2-5 hundred rounds a game

Yep, if you can find a place that has high pressure bulk tanks, lease it from them and have them fill it.

Cheapest method would be the series of scuba's and be happy with 3K fills.

No way, I got a bulk tank and it costs me very little! They cost us $100 per year on the lease and $14 per fill. A scuba is $4 per fill here to 3000!

Was that a high pressure tank? Excellent price then. I had a problem finding anyone local with HP bulk tanks, they mistly had lower pressure tanks (like 2000psi).

i forgot to mention that you cascade multiple scuba tanks. this meaning one tank for volume fills and one tank for high pressure fills.

Yep, cascading helps tremendously. Yes, those tanks I lease are 444 cu ft tanks and 4500 psi. The more expensive one's you get at welding places are usually 6K tanks and those are about $50 per fill, but they are also nitrogen generally!

ended up getting the scuba fill first, then later maybe go with 4500psi + Lease on a big tank
