CA 2152858

A vacuum system for a building, in particular, a building with multiple dwellings. There is a fan to develop suction mounted in a compartment having a dust inlet and a dust outlet. A motor drives the fan. The motor has a drive shaft to extend into the fan compartment. There is a dust collection head communicating with the inlet. A dust disposal pipe connected to the outlet extends to a remote dust receptacle. There is a vent for the dust receptacle to prevent dust being fed back into the atmosphere. The system can operate satisfactorily without a filter. It draws dust in from a point between the source of the dust and the dust receptacle so that suction is not applied through the contents of the dust receptacle.
