The airless paint sprayer was investigated as an alternative to compressed-gas spray systems. The airless sprayer was adapted to a conventional agricultural spray nozzle system. In addition, modifications to the airless sprayer's on/off switch were made to achieve a more consistent delivery. The equipment was found satisfactory for applying either emulsifiable concentrates or wettable powder herbicides at typical concentrations in water. The addition of a conventional conveyer-belt system completed the steps necessary to make the commercially available airless sprayer a viable alternative to compressed-gas propulsion systems.
