CA 2523454

A vacuum cleaning apparatus comprising a housing defining a vacuum chamber. The housing has an upper wall that defines an upper end of the vacuum chamber, and there is a fan/motor unit positioned in the vacuum chamber below the upper wall defining the chamber. The air is drawn into an opening in the housing and flows through the vacuum chamber upwardly through the fan and motor to be discharged into the atmosphere. A noise suppressing section can be position in the air flow from the fan motor unit to the exhaust opening. The noise that is generated by the fan/motor unit is in large part dissipated as it is transmitted into the vacuum chamber at a location below the upper containing wall defining that chamber.
