neoprene counter lungs

PCDiver · 30th October 2005, 06:28

Our neoprene guy came back with "a big NO" after he reviewed the details of neoprene lungs. His boss had told him no to do it, especially after he heard that I wanted several. CE certification strikes again. I begged to do it as prototypes or homebuild kits but he would not give in.

Mike, can you help us out?

Hey guys,
I'm going to Brasil in few days. Send me the specifications and I'll try with a friend of mine down there. He owns a wet suit/ dry suit factory down south Brasil and I can do a trip down there and talk in person with him.
If you want, send me the specifications to my e-mail mike@protecdiving.com .
Cheers,

Hi Mike,

thanks for the reply. I'm going to wait to see what happens with the BM-CL's from Decoweenie. But others might still be interested. You need to ask Dave for the design specs, since it is his design.

I posted earlier that I very much enjoy diving the ISC Meg neoprene counterlungs and see the recent post regarding a vendor for making such lungs.

Just want to add a word of caution here before it goes down the wrong road;

You must request the size of the opening, not simply request quantity of holes in each lung. The port hole must be of the diameter of a specific exhaust valve / inflator valve / or T-piece .

Be sure that you can insert the inner base of whatever port fitting that you are installing in the hole. Yes neoprene stretches, but you want a tight tolerance to the opening.

Can the parts you are planning to use be installed after the lung is constructed?

Be sure that the inner fittings are smooth, as example the inspiration fitting has a rubber boot to protect the bladder. At the same time you must consider a stand off or breathing space, as example SiTech dry suit exhaust valve has a cage to prevent the undergarment from sealing off the air flow. The Meg inner “nuts” have ridges or passages that can indent the neoprene and if stored incorrectly cause punctures in neoprene. I know ISC has changed this inner nut to a smooth ridge on current units to prevent puncture.

Neoprene is tough, but like neoprene drysuits that I have owned – they leak! Pin holes are not uncommon side effect of neoprene and dive buddies comment to me regularly that I have Alka Seltzer bubbles…goes with the territory.

The neoprene should be smooth inside, meaning raw unfinished neoprene so you can easily drain, rinse and sanitize the surface. You do not want nylon fabric lining the counterlung.

Consider loops, straps or other fitting on the counterlung to not only fasten at the top or crotch strap bottom, but on the side for attachment to harness. Since the list sounds like a variety of ccr’s this may not be possible.

I had three sets of ISC CL and recently sold one to a KISS / Inspiration instructor in WA so she could install a set on her KISS Classic. I’m not in the market for any, but appreciate the value of how snug and trim the fit is with neoprene, and can see a need for such a product. I know the ISC lungs are pricy but the fittings are all top quality, and they are labor intense for these guys to make.

The sizes of the all holes are for Drager P-conectors. And I would like that the holes will protect with a "Rubber Donnut" Inside and out of CL. Like the holes in the drysuits.

Yes.

teomannaskali · 10th April 2006, 21:59

Would it be possible for me to have the drawings and specs for the counter lungs?

I know some people who make drysuits, Ill ask them how much it will cost for them to make the CLs.

BTW you do you have bladders in neoprene counter lungs?

Thanks for any info
