UPDATE
Here are a couple of  pics of the greatly modified RGU-2 scrubber that didnt make it into the first posting.
The new gray exhale tube extension and white nut do several things:
*     Redirects the exhaled gas out thru the newly 'ported' bottom cap and directly into the  single counterlung.
*     Compresses the pellet charge compaction spring (black), and
*     Secures the bottom cap in place.

The sealing o-ring, which formed the critical water-tight seal in the original RG-UF/M refillable scrubber is no longer 
truly required.  This because positioning the RGU-2 scrubber  inside the counterlung eliminates the need for a critical
watertight seal.  This eliminates a common  critical failure mode from the original RG-UF/M  refillable scrubber
design, which was previously exposed to the ambient water. .

The top and bottom screens are presently  made of .006 in. thk. woven stainless steel wire.  
Later, these will be replaced by formed, .008 in. thk.,  stainless steel sheet, with .020 in. dia. perforations

Dan Dunfee build a great new rebreather. He used the former East German RG-UF/M as a donor. He made a beautiful design that could be used for your future homebuilt project! The small East German tank rebreather is a nice unit that can easily be found since large numbers are produced. This page written by Dan shows all his design considerations and ideas. I would like to thank Dan for sharing his thoughts and allowing me to publish his article first! In the description of the unit you will find all the data you need or else you can ask Dan by sending him an email!
