<p>A handheld device and method for clearing obstructions from spray nozzles includes a housing, a gas valve system contained within the housing, and a nozzle body attachment structure. A trigger associated with the gas valve system is operable to release a blast of compressed gas through the attachment structure. A spray nozzle placed in contact with the attachment structure receives a blast of compressed gas to clear obstructions. The attachment structure interfaces with both the normal discharge side and the normal inlet side of the spray nozzle to allow compressed gas to be blown through the spray nozzle in both directions. A backup tool is provided to engage a backside of the spray nozzle to prevent a spray tip within the spray nozzle from blowing backwards out of the spray nozzle. A backup tool cover has a slender projection for removing screen filters associated with the spray nozzle.</p> |
