The Mentes Rebreather from the czech republic uses electronics from  Jurgenson Marine. The mechanical construction of the head of the rebreather is based on a sensor chamber fitted with a water trap. The construction of the head is made in such a manner that  both breathing hoses - for in and out breathing – lead to a nozzle that is  located on the side of the head of rebreather. This is done thanks to small channel inside the head. In rebreather a radial scrubber of own construction is used. It is made from Delrin and stainless steel. The radial scrubber has pressure plate on springs and the plate presses the absorbent so it helps for a better filling of the scrubber with the absorbent. Electronics are located in a case made from Delrin, and the cover plate is from Dural. The control and handling is done via piezo-switches. More on construction can be seen here on detailed pictures of the unit.
