The core and orifice tip design produces a hollow cone spray of very fine droplets using liquid pressure alone. The metal series are available with or without an integral strainer, and with a medium or extra wide spray angle. Separate nozzle heads have a straight thread for connection to the pipe threaded nozzle body. This enables them to be removed for cleaning easily and replaced without the use of pipe joint sealant. Nozzles are available with 1/4" male or female NPT, and with flow rates from 0.37 to 26 gallons per hour at 40 psi. LJB nozzles include an integral strainer screen. Nozzle orifice and core tip are stainless steel with the body and cap in brass or type 303 stainless steel.

The JJB nozzle system uses the energy in compressed air to produce highly atomized sprays at low flow rates. There are many interhangeable components that can be assembled to achieve a variety of spraying options.

Spray Set-Ups. JJB nozzles produce eight distinctly different types of sprays, depending on which interchangeable air and fluid caps are selected. The spray type and flow rate are determined by the "set-up" - a specific combination of one air cap and one fluid cap.

Internal Mix Set-Ups. Liquid and air streams meet within the nozzle and are mixed together and expelled through the same orifice(s). This internal mixing means the streams are not independent; a change in air flow will affect the liquid flow. This makes precise metering of the liquid more difficult than with an External Mix Set-Up. Internal mix Set-Ups are able to produce the finest atomization of any of the JJB set-ups, but they are generally not suitable for use with liquids which have a viscosity that is above 200 centipoise.

External Mix Set-Ups. The air and liquid streams exit the nozzle independently and are combined and mixed outside of the nozzle. Because there is no connection between the air and liquid lines within the nozzle, the air and liquid flow rates can be controlled independently, allowing precise metering of the liquid. The atomization can be controlled by adjusting the air flow rate - more air produces finer atomization. In most cases these set-ups do not atomize as finely as Internal Mix Set-Ups. External Mix Set-Ups may be sued with liquids having a viscosity above 200 centipoise and for abrasive suspensions.
