Abstract
A debris blower incorporating a nozzle (e.g., removably attachable nozzle) formed from first and second mating halves, wherein the nozzle provides an airstream that oscillates as a result of dynamic fluid effects of airflow passing through the nozzle. As a result, an oscillating airstream may be produced without the use of complicated moving airflow control elements such as louvers and vanes, and without requiring manual manipulation of the blower by the operator.
