The working principle of a debreather is very simple. A primitive version of the closed-circuit breathing system used in inhalation anesthesia. We need an air pump, carbon dioxide absorbent (soda lime) respiratory pipeline, the bag we will put our heads in (ripstop and airtight), silicone for air insulation.
As in the picture, the air pump sucks the air inside the bag and sends it to the box filled with soda lime. The carbon dioxide free air returns to the bag again. The construction of this system is very simple. The important point is a good air insulation. It is easy to insulate the places where the pipes are connected to the air pump and soda lime box with silicone. We need to be careful while isolating the places where the pipes are connected to the bag.
Easy to find air pump, respiratory pipeline, and soda lime. Soda lime can be purchased online as 20 kg packages in the country where I live. The price is 65 dollars. I could not decide which material to make the bag from. It is also necessary to choose the right air pump. I think this system works. What do you thinking about that?
