A rebuildable atomizer (RBA) is an atomizer that allows the user to assemble or "build" the wick and coil themselves instead of replacing them with off-the-shelf atomizer "heads". [18] They are generally considered advanced devices. [91] They also allow the user to build atomizers at any desired electrical resistance. [18]
A spray nozzle or atomizer is a device that facilitates the dispersion of a liquid by the formation of a spray. The production of a spray requires the fragmentation of liquid structures, such as liquid sheets or ligaments, into droplets, often by using kinetic energy to overcome the cost of creating additional surface area.
When ultrasonic nozzles are used, the spray can be made to be as dry as necessary by the nature of the small and uniform droplet size, by varying the distance the droplets travel and by applying low heat to the substrate such that the droplets dry in the air before reaching the substrate.
The atomizer drive gives the high speed to the wheel. Clogging can be a problem for spray nozzle systems, whereas rotary atomizers can work in such situations. A rotary atomizer can manage large amounts of abrasive and non-abrasive feeds. A rotary atomizer can take very viscous liquids. A rotary atomizer is flexible according to particle size.
Examples include fuel injectors for gasoline and diesel engines, atomizers for jet engines (gas turbines), [12] atomizers for injecting heavy fuel oil into combustion air in steam boiler injectors, and rocket engine injectors. Drop size is critical because the large surface area of a finely atomized spray enhances fuel evaporation rate.

An atomizer operates in a similar fashion except that the actuator is a pump which when pressed a few times creates the pressure to aspirate the fragrance from the container through a tube into the actuator and spray nozzle. Because the container is not constantly under pressure it may be made of glass or plastic as well as metal.
