FFM on Inspiration

Mdemon

Has anyone had/heard of any bad experiences related to CO2 hits and Full Face Masks - especially AGA masks and on the Inspiration?

The Inspo manual frowns on it. The Commies seem to use them without a problem...

Any thoughts?

I use a DR-600 Widolf with no CO2 problems. It does have a small oro-nasal cup, so that helps. The only hard part is smearing enough anti-fog on to keep it clear, but a goo called 500PSI works well.

I guess that makes me a Commie!

I can't help thinking that you are taking Commie to mean one of our Eastern comrades!

The AGA has an inner cup too. I may have to swap the valves to circulate gas in the opposite direction to help with the fog. BTW, what's in the goo? Is it an oil-based thing or what?

I was wondering about the volume of air from the inlet mushrrom valve on the DSV, through the DSV and to the inner cup. That's a fair amount of CO2-laden gas which has to be re-breathed partially. Not a vast amount, but I wonder if the effects are cumulative/enhanced? This was what prompted the original question...

Yeah, I made the assumption that was what you meant. Is there another meaning?

I haven't noticed any problems with the set-up, but then I havn't gotten into a situation where I was working hard while rurnning deep on the thing.

As for 500 PSI, I don't think there's any oil in it, but will check for you.

commie = commercial diver.

LOL! You Americans! I meant as in Commercial divers... (Or "puppets", since they are always dangling on the end of bits of rope... )

Thanks for that. I have seen vaseline used in cold weather on respirators...

I think AP have one in the pipeline - I am sure I have seen pictures of it. They initially recommended the internal mouthpiece like the scubapro FFM has but to me that defeats the object...

Yeah, I didn't think there were any of the other type left, except about a bazillion Chinese folks.

We tend to call Commercial DiverTenders "Monkey Tenders" because of the resemblence to the organ grinder and his monkey on a string. You can imagine then what the divers are called.

Still haven't had a chance to find my Jumbo Economy-size bottle of 500PSI because I've been attending a conference. I'll do a look-up today for you.

I don't know why AP would want to get into that market, because we've already got the Kirby-Morgan KM48 and the OMG oral sex masks.

You are right, though, in that the two best reasons for a FFM are cold protection and comms, and you sure can't use comms very well with a rubber donkey **** in your mouth. Although to be fair, as has been mentioned, the OMG version has a telescoping provision, and the KMB version has the "unobtanium secret weasel" re-breather version.

I love my Widolf DR-600, but they are hard to get at the moment. I've used the EXO-26 a fair amount, but to me, they are kind of clunky. The "Reef" has its' advocates, but in my experience, they are too lightly built. (Note: That is just personal experience from banging around on the bottom in PSD work.) The Divator MkII (or AGA) is a great mask. It is strong, light, and has a good "picture window". Fitted with a Divematics DSV and good comm's (like OTS), it makes a truly fine combination.

(NOTE: No creatures of any kind, including commercial divers have been harmed in the production of this post. The slang comes directly from friends who are currently commercial divers. In the case of the OMG and the "Super" mask, no slur was intended. "Oral sex mask" is merely a description of the physical way the mask functions. Devotees of those masks should calm down, take more of the tablets your physician has prescribed, and step away from the Weapon of Crass Destruction (WCD) a.k.a. their Internet Keyboard.)

Have a great afternoon! Hope the weather is better over there. It's been a real circus over here already this year.

Cheers!
Rob

The mask that's shown on their website and the Evo flyer is a Dräger Nova FFM.
IIRC Janwillem even has some pictures from dive show on his website when AP had them at their booth.

I actually have one of the draeger FFMs in my possesion, I found one of three in the USA at DEMA last year and want to plumb it to my meg. the problem is the ffm has a draeger P port for an attachment system, so I need a DSV that will fit the meg hoses and also has a P port for a mouthpiece. Draeger sells a DSV with P port but it only fits dolphin hoses. I am working with ISC to machine up the proper part but its slow going as they are so busy building meg's.

One of the big issues with using ffm's with a rebreather is CO2 buildup in the mask, you must have a mouthpiece to breathe from so the mask doesnt become a counterlung on your face. The draeger mask has this covered with a retractable mouthpiece on the inside of the mask, just let go your lips to use comms and then reach out with your lips to regrasp the mouthpiece. the unit also has a neat pair of clamps that look a bit like winshield wipers you use to pinch your nose for clearing. The mask is very comfortable and I have some great anti fog, but still havent been in the water with it.
