ABSTRACT:
A blow-off nozzle assembly provides protection for users, without increasing the noise level, and also protects the nozzle from breakage if dropped. A circular cross-section rod assumes an oblong configuration defining an oblong shaped opening, with circular cross-section support posts extending from one side of the rod. The support posts are received by a casing having channels on opposite sides of a linear array of individual jets of a multi-channel substantially flat jet nozzle. The oblong shaped guard is mounted so that it is spaced from the nozzle in the direction of air flow from the nozzle with a linear array of jets centered within a geometric projection of the opening. The guard prevents deadending, so that the pressure of compressed air if the guard were pressed against a worker's skin would be below the OSHA standard of 30 p.s.i. An outer shell of high impact plastic surrounds the nozzle, with the jets extending from the front end of the shell, and impact absorbing material (such as a plastic foam) is disposed between the shell and nozzle.
