Hi, The exploded view of the vaporizer is basically its anatomy as we wanted to show its guts, but in reallity there are only 3 pieces loose: the diffuser which goes screwed in the cap, the cap itself, and the body which is the assembly of two components: an aluminum chamber and a wooden body. The diffuser which is the little tiny piece with 4 holes does not need to be removed unless you want to clean it as vaporizing with standard lighters could form some soot around the diffuser; A microtorch is ideal to avoid soot IMO, also the torch should be single nozzle. The chamber is threaded outside to minimize heat transfer to the outside and therefore making an oven effect. Also "firlterless system" means that we dont use ceramic filters, and the diffuser jet does the job. Also as the chamber is long and its diameter small, the herb are loaded in a way that works as a filter itself.( tool included for easy removal too). Lithe is simple, and efficient. the light brown that was on sale is called Guayacan.
