The Exair 1/8 NPT HollowStream Liquid Atomizing Nozzle has a stainless steel construction which provides durability and corrosion resistance. Liquid is supplied into the body of the nozzle, creating a swirling action within a vortex chamber. The vortex then produces the spray pattern when the machined nozzle breaks the liquid surface tension as it exits the orifice into a controlled spray angle. The HollowStream's tangential flow design is vaneless, with wide open internal features to resist clogging while producing a uniform distribution in a ring pattern. The open, right-angle design is compact and intended to serve in applications involving liquids that are thicker, or containing particulate up to 250 psi.
