The BETE SA series is a two-substance nozzle and can be driven with any gas (or compressed air). It works by means of a three-stage process for a relatively low compressed air consumption. The two-phase atomization ensures more efficient atomization. The SA series is designed for high reliability in aggressive conditions and is available in two sizes and many versions including lances and flange feedthroughs. U.S. Patent #5,240,183.
Air atomizer nozzles atomize liquids by combining liquid and compressed air/gas at low pressure to form a very fine spray. They can form a fan-shaped or cone-shaped spray pattern, depending on the design of the nozzle
