Deflector flat fan nozzles for lubrication applications

The deflection type nozzle produces the flat fan pattern by deflecting the fluid stream against curved surface after exit from the nozzle orifice. The impact of the fluid on the deflection surface causes the desired atomisation and the geometry of the surface shapes the resulting spray into a flat fan pattern.

These nozzles produce an evenly distributed flat fan pattern with some small amount of tapering at the ends of the spray. The even spray distribution, wide range of different spray angles and flow rates makes these nozzles a suitable choice for use in many lubricating spray bars.

Note: The atomisation achieved by these nozzles is relatively coarse which may preclude them from being used in very fine lubrication applications.

Less clogging

Because the pattern is formed by the curved impact surface rather than the shape of the orifice it means that the orifice can remain circular. A circular orifice is less prone to wear and clogging. This makes it more suitable for spraying viscous lubricants.

Wider spray angles

Additionally wider spray angles can be achieved by varying the curvature of the deflector plate. This means that flat fan patterns up to 145 degrees can be achieved allowing lubricant to be distributed further.
