Blower unit

A blower unit having a front and rear and laterally spaced sides, the blower unit comprising:

• a frame;
• at least one wheel on the frame through which the frame can be supported upon and moved over a subjacent support surface;
• a handle assembly with at least one gripping region that is configured to be engaged by a user situated at the rear of the blower unit and at which forces can be applied by the user to reposition the blower unit relative to a subjacent support surface;
• a source of pressurized air having an outlet at which a volume of pressurized air is discharged;
• and
• a pressurized air handling system on the frame comprising a conduit assembly defining first and second flow paths through which pressurized air from the outlet of the source of pressurized air is delivered respectively to first and second outlets,
• the pressurized air handling system further comprising an air control system,
• the air control system having at least first and second states,
• the air control system in the first state causing one of:
• a) substantially all of the volume of pressurized air discharged at the outlet of the source of pressurized air to be directed in the first path to the first outlet;
• or b) only a part of the volume of pressurized air discharged at the outlet of the source of pressurized air to be directed in the first path to the first outlet,
• the air control system in the second state causing one of:
• a) substantially all of the volume of pressurized air discharged at the outlet of the source of pressurized air to be directed in the second path to the second outlet;
• or b) only another part of the volume of pressurized air discharged at the outlet of the source of pressurized air to be directed in the second path to the second inlet,
• wherein the air control system further comprises a user operable actuator system with an actuator element that is situated adjacent the rear of the blower unit and operable by a user situated at the rear of the blower unit to change the air control system between the first and second states,
• wherein the source of air comprises a centrifugal fan, the centrifugal fan having an impeller assembly that turns around an axis that extends in a side-to-side direction.
