Soviet gasmask filter(regenerative)

[Datrus]

A "regenerative" gasmask filter. Never seen these before. Maybe gasmaskuk can tell something about it?

Not from a gas mask as such, but from an IP4 or IP4M Rebreather, these were only suitable for use on land and not under water like a conventional rebeather

Thanks

Thanks a lot mate. I only have a google translation to do with. A friend in Belarus sent me a lot of pics today of thing he has. Looks a little odd this filter.
