Others Air Tanks Plus (ATP)

[Ezana4CE]

I haven’t seen anything posted about Air Tanks Plus products. I like their fill whips and I bought a tank bag from them, but I’m trying to better understand the need for their Stikman device. I’ve read people say that it helps with filling guns, but I’ve gotten by by manually controlling the air flow into the gun’s reservoir using my SCBA tank valve. I also see two male foster fill nipples on the bottom of the Stikman and read that it can be used for cascading SCBA tanks. This is something I have never done and know little about. If you have any experience on cascading tanks (for tethering to big bores) I’m interested in your input. As far as filling systems or set ups go, who is using an ATP Stikman and what benefits have you gained by using it?

@hameditor In my experience they are a good shop. They have quality products, although some can be pricey. They are based out of the Sacramento region of Northern California. As far as the fill system goes, I don’t see the need for this piece of fill equipment when I can fill a Benjamin Marauder pistol directly from my SCBA without overfilling and locking the gun’s valve.

As for cascading two tanks while tethered to a gun, I’m trying to understand how running them in series increases the amount of usable air using this device. Why not tether the rifle to one tank and when the pressure drops below the desired level, switch tanks? If you have your own HPA compressor setup the small amount of air lost to bleed the tethering line in order to swap out tanks seems negligible. I don’t understand what I’m missing here. And my apologies. I thought I pasted the link to the product in my initial post. Rough week.

I’m pretty sure cascading isn’t typically used for tethering. If I was tethering and was going to be shooting for hours and hours and hours I would manifold my SCBA’s and not cascade. What’s the difference ? Manifolding is where you would take two or more SCBA’s and connect them to a Y or T fitting and then with BOTH tanks open they would go to an output hose that would go to a regulator set at your desired pressure and just shoot till your gun and SCBA’s are at the guns minimum pressure. That’s a ton of shooting.

Cascading is when you have two or more SCBA’s manifolded together but only open one tank at a time to fill a smaller bottle on your bottle gun or tube gun.
It works like this: You take your gun and connect it up to the manifolded SCBA’s.
Let’s say your gun max pressure is 4000psi and both SCBA’s are at 4500psi. You fill your gun to 4000psi and now the SCBA that you filled from is less than 4500psi but more than your guns max 4000psi. At this point there’s no need to open the other SCBA tank because your gun is topped off to 4000psi. At some point after doing a lot of shooting and filling the SCBA that you have been using will drop below 4000psi and your gun will not have a full tank. So at that point you close the valve on the low tank and then top off your gun with the full SCBA. This is referred to as cascading. It is the standard set up in dive shops, fire stations and gas suppliers that fill tanks like for ambulances that have the smaller oxygen tanks. It’s a mathamatically and empiraclly proven method to get the maximum number of fills out of multiple storage tanks.

Cascading is best done by using a manifold to connect all supply tanks together so as not to waste air by having to bleed then disconnect, then connect the next higher pressure tank.
At some point your SCBA’s will be down below the guns max fill pressure. Then at that point you must refill SCBA’s or live with short fills.

I’ve bought their tank bags but I’ve never understood the Stikman or whatever it’s called. I’ve never felt a need for anything other than what I’m using although I’m sure he’s made it because someone out there or he himself needed such a thing. Excellent tank bags BTW

Thats awesome makes a lot of sense thank you for that.
