Nozzles for lubrication
Spraying of viscous fluids
Many lubricants are viscous and this can present spraying challenges. In particular if using air atomising nozzles the action of the air on a viscous fluid can cause clogging problems. Using external mix variants, where the air is mixed with the fluid after exit from the nozzle, will help mitigate this problem.
