I have a Draeger Dolphin. I've been interested in getting a diffuser, but I have not been able to find a direct replacement part. I have had others tell me that I can just use a piece of foam, but I can't seem to figure out how to install it and still have a working Rebreather. If anyone has a Draeger direct replacement part # or can direct me to some good instructions on how get my bubbles diffused, I 'd appreciate it. Thanx Dave
