Elliptical orifice Flat Fan Nozzles for Lubrication

With these nozzles the spray pattern is formed by the exit of the fluid through shaped orifice.

The tapered nature of the flat spray pattern means that spray distribution is not entirely even.  The ends of the spray pattern have less fluid delivered.  In order to achieve an even a spray bar with a series of nozzles with a slight overlapping of the spray patterns from the individual nozzles should be built in.  Once the level of spray loss at the edges of the pattern are known then it is just a matter of simple trigonometry to correct by overlapping the tapered edges.

Lubricating Spray Bars

These nozzles are suitable for lubrication applications where a moving conveyor of material needs to be lubricated.  In a spray bar they can provide an even coating of lubricant as the material moves past.  As lubrication generally requires only a small amount of spray the low flow (BJ) variant of this nozzle design is often suitable.  If used in a spray bar format over a conveyor some degree of control over dosing can be achieved by varying the speed of the conveyor.
