摘要： A pneumatic cleaner (10) that can be worn as a backpack has a reduced unit overall depth. The impeller shaft (53) is mounted at an acute angle. Tangential airflow chambers (67,80,86) are disposed around the motor assembly (42) and substantially surround the impeller (53) . Two of the airflow chambers (80,86) extend substantially the entire overall unit depth, and have lateral lengths that exceed the overall unit depth.

摘要： Disclosed herein is a vacuum cleaner (10) having a housing (12) defining a blower port (62), an exhaust port (66), and a flow path between the blower port (62) and the exhaust port (66). The vacuum cleaner (10) also includes a removable cap (64) assembly for the blower port (62) to direct discharge airflow via the flow path to the exhaust port (66). The removable cap assembly (64), in turn, includes a cap head that engages the blower port (62) to close the blower port (62), a cap body coupled to the cap head and inserted in the flow path, the cap body comprising a frame through which the discharge airflow passes, and a sound-influencing material supported by the frame within the flow path to reduce noise effected by the discharge airflow. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.
