A blower can have a housing having an inlet, an outlet, and a volute channel in fluid communication with the inlet and the outlet. A fan assembly may be at least partially supported by the housing, and include a fan, and a driving mechanism can be coupled to the fan assembly for rotating the fan to create air flow through the housing. A tube can be removably connected to the housing and in fluid communication with the outlet to direct air flow exiting the housing, and a guard can be at least partially received within the tube. The guard can have guard features preventing access to the housing and attachment features attaching the tube to the housing.
