  • Patent number: 8075656
    Abstract: A separator assembly for removing material that is entrained in a gas stream. The separator assembly comprises a housing having inlet and outlet ports for the gas from which material is to be removed. The inlet and outlet ports are located toward the upper end of the housing. A flow director is positioned so that gas flowing into the housing flows over the flow director so that the incoming gas is made to follow a generally helical path within the housing. The separator assembly also comprises a shield which extends across the housing towards the lower end thereof so as to leave a collection space between it and the lower end in which material that is separated from the gas stream can collect. There is at least one opening in or around the shield through which the material can flow past the shield into the collection space. The face of the shield which is directed towards the upper end of the housing is bowl-shaped.
