  • 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.

  • Patent number: 8002865
    Abstract: A separator assembly for removing material that is entrained in a gas stream. The separator assembly comprises a housing having a head part which provides the upper end of the housing and a body part which provides the lower end of 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 separator assembly further comprises a liner sleeve which covers at least a part of the inside wall of the body part between the shield and the upper end of the body part.

  • Patent number: 7264660
    Abstract: Apparatus for drying a gas comprises an elongate housing having an inlet port and an outlet port for the gas. The housing comprises at least two axially separable parts which can be separated to allow access to the interior of the housing. A cartridge contains an adsorbent material through which gas can flow axially from an inlet end which is in fluid communication with the inlet port to the housing towards an outlet end which is in fluid communication with the outlet port from the housing. The cartridge has a plurality of flexible vanes at the inlet end which, when the cartridge is located within the housing, are twisted so that gas flowing over the vanes has a circumferential flow imparted to it around the axis of the cartridge.
