- Page 10 MAIN COMPONENTS OF SPRAYER NOZZLES The nozzles have the job to generate droplets and distribute them uniformly over the surface being sprayed. Flow, angle and droplet sizes vary according to working pressure. Operating with pressure over that recommended by the manufacturer will decrease the nozzles' life. This sprayer is equipped with alumina (ceramic) nozzles, very resistant to wear and to chemical action, and mounted as shown in the figures below.
- Page 11 MAIN COMPONENTS OF SPRAYER The fan has a locking device designed to be used during the tank filling, agitation of chemical mixture while spraying, as well as for spray lance application. The use of this device reduces power consumption in any of said operations. To turn the fan off, pull the lock and give it a quarter turn.
