Physical description
The Renton circle valve absorber has been sectioned to show the valve connection points. The inside is a creamy brown colour, encased in black on the outside. A larger silver metal valve runs through the centre, and to it attaches a flat, reflective silver metal disc as a dial indicating "EXH", "ABS", and "REB", with a black needle. The system includes tubes and valves for oxygen entry, gas expiration, connection to soda lime cannister, rotary valve, and rebreather bag, with a broken, deteriorated segment of the bag still attached.
