Our patented, self-cleaning polyurethane spray nozzle design has no metal parts to rust and corrode and is sturdy enough to stand up to whatever volume of water your application requires. Spray nozzles come in a variety of shapes and configurations but they're all designed for one purpose: to deliver water to the screen deck to wash material. Unfortunately, they are too often taken for granted and forgotten until they don't work. For that reason, we've designed ours to be maintenance-free (well almost). They're self-cleaning, and deliver the designated amount of water evenly across the deck, without blowing a hole in your screen media.
