Two Distinct Configurations
Axial and Deflector
There are two fundamental configurations of flat spray nozzles: axial and deflector. The axial design directs the spray pattern axially to the orifice, while the deflector design employs a deflector shield or plate to create a flat fan spray pattern. The deflector design typically positions the spray pattern between 20 to 30 degrees offset from the exit orifice. Notably, deflector designs often exhibit enhanced clog resistance due to their round orifice structure, contrasting the axial design that involves a drill/mill operation to create a “cats eye” type orifice.
Choosing the Right Design
Deflector designs, while producing slightly less impact at equivalent flows/pressure, excel in clog-resistant functionality. The narrower the spray angle, the greater the impact at a given distance, making narrower spray angle nozzles ideal for challenging cleaning tasks. Conversely, wider angle nozzles find their niche in less intensive washing and rinsing applications.
