Auto Air v No Auto Air

Moray Brown · 26th October 2006, 18:00

Would be interested in other's comments on taking the auto air off, and just having LP Inflator.

Since I usually dive with the 13cf tanks in my Optima, I did not install a Auto Air or attach an OC regulator to my Diluent tank. I carry offboard instead. Those 13's won't last very long on OC.
Aloha,

I still use the auto air. So far its performed OK.

Not sure about the long term as I'm not exactly a fan of them. Suppose the first time it starts weeping it'll force me into the change.

If you decide to just remove it then either fit a 2nd stage or pressure relief valve on it.

Cheers

Air2's and such are great if you have an 80 strapped to your back, but for ccr, its best to remove the failure point of a reg that only has a few cubic feet behind it and just have an inflator there. If you really need the gas from that cylinder, then pop the LPI hose off and plump it to your offboard injection port, or access the gas open loop from the DSV and ADV. You really dont need 3 access points to a 13 that will run out just when you get calm again. the only thing worse than running out of gas on a dive....is running out of gas TWICE.

Auto Air's work for me

Admit i have had to crank it down a touch to stop it bleeding off, but it saves me on shallow (up to 35m)diving from having to take a stage with me.

I.E off to Egypt 2morro on a Liverboard diving the Northern Wrecks for a week. The Auto air saves me from having to take an extra reg with me and hiring a pony bottle out there. As the 3ltr inboard is fine for me as bailout on typical redsea diving.

So all in all it also reduces weight, and we all know how hard it is to travel with a CCR nowadays with such tight weight restrictions

Gareth,

How did you pack your CCr for the airport? Are you using the AP box? I am going to Egypt next week and havnt packed yet... It might be the Inspiration and a thong for the week!!!

Fair point, but the same benefits can be had by installing a power inflator and plumbing in a normal reg onto the Dil side.

On my rig I have a GCS so I can use the 3 liter of dill if need be and also access the 3 liter of O2 at 6m so all of the gas is available.

Plus the Auto air is a big old thing.

Wouldn't like to rely on 3lt down to 35m.. reckon you'd suck that through before completing stops

Kinda like the idea of all onboard gas being used for the CCR only.
