B05B SPRAYING APPARATUS; ATOMISING APPARATUS; NOZZLES (spray-mixers with nozzles B01F25/72; processes for applying liquids or other fluent materials to surfaces by spraying B05D)
Description
B05B covers the design and construction of equipment that disperses fluids through spraying or atomising processes. This includes spray guns, atomizers, nozzles, and associated apparatus for applying liquid or powder materials to surfaces. The classification encompasses various spray mechanisms (pressure-fed, suction-fed, rotary atomizers) and nozzle designs used across industrial coating, agricultural, and cleaning applications. Detailed technical specifications for individual spray methods and specialized nozzle types are found in subordinate classifications.
