Water is pumped through a spray system containing nozzles in a variety of sizes and shapes to produce virtually any spray pattern desired. Solid particulates in the water can spell disaster for a spray nozzle. Nozzles may become clogged emitting no water or the internal shape of the orifice can be distorted from erosion or deposition resulting in distorted spray patterns. These problems cause uneven distribution and loss of crop yield.

Spray nozzles to be protected include irrigation sprinklers, drippers and center pivots or livestock misters for cooling. Orival filters protect spray systems by removing suspended solids that could clog, erode or distort.
