BETE MicroWhirl nozzles offer outstanding fine mist or fog with a rugged, pinless design that ensures drip-free performance. They include a 70-micron polypropylene filter. A 200-mesh 316 Stainless Steel filter option is available as an alternative. A safety wire hole is also available for added security. The nozzle operates with a minimum pressure of 100 PSI (7 BAR) and delivers versatile spray performance, producing mist at lower pressures and fog at higher pressures. Droplets are typically small enough that buoyancy is significant compared to gravity, allowing drops to appear to float. In actuality, particles fall very slowly in the absence of upward airflow.

How Swirl Misting Nozzles Work

BETE engineers patented the whirl fine misting nozzle in 2002. Misting and fogging spray nozzles traditionally use either an impingement or air-atomizing design to produce small droplets. Alternatively, whirl misting nozzles convert the fluid's head pressure into kinetic energy within a swirl chamber. The discharged fluid breaks up the droplets from the centrifugal force. MicroWhirl nozzles utilize a vortex to create a fine mist, increasing reliability and performance compared with traditional methods.
