100 cu in - mini tank questions?

[GA_LeadHead]

Forgive my ignorance as I'm still new to using scba tanks. Currently I use an Air Marksman 98cf tank that I fill/top off via a male foster on the tank valve assembly. Just pop off the hose and connect directly to tank.
I'm looking at adding a 'mini' 100cu in tank/bottle to use as an on the go solution for air. Looking at the Air Venturi mini wingman. I cannot tell from the photos if it has the male foster connection for will I need some other adapter to fill it? Or do you fill through the hose via a male-to-male foster adapter?

Thanks

@GA_LeadHead It’s the valve you should be looking at. Unless you have a female foster fitting connection on your compressor for filling tanks to fill via your fill whip (I don’t recommend this method of filling tanks), then you’re going to fill the SCBA tank through the valve.

The mini wingman appears to have the same Jubilee valves as the larger Air Venturi SCBA tanks. They are filled using a DIN300 connection from a compressor. To access the DIN300 threads the fill whip must be unscrewed from the valve (see the red circle in the photo below). Then you will screw in the DIN300 fill adapter in the same threads from where you unscrewed the fill whip.

Why not fill through the fill whip? I just pull the gun fill fitting and put in a male to male foster and start the YH. Then I close the vent on the YH and open the valve on the tank. I have a one way valve on my extra air filter so the YH has to get up to the tank pressure before it can pump past the filter. Seems to work fine. I do vent a not trivial amount of air when I am done, however. It's venting the filter and the lines. I'm aware a line could burst, is that your concern? While it is a risk it could also happen filling a gun.

@JimD I believe that it puts unecessary wear on the fill line. Why do that when the tank can be filled directly with a DIN fitting? Personal preference thing I guess.
