  • Patent number: 6409786
    Abstract: A filter assembly for collecting material that is entrained in a gas stream includes a housing having inlet and outlet ports for the gas that is to be filtered. The housing includes an end cap in which at least one of the ports is provided, and a body section in which a tubular filter can be located arranged for the gas stream to flow through its wall provided by a filter medium, the end cap and the body section being separable to allow access to the inside of the housing. A tubular member, which might be a filter element or a conduit for directing a flow of gas to a filter element, can be sealingly connected to the end cap in fluid communication with one of the ports therein. The tubular member includes a tang which can be received in a recess in the housing when the tubular member and the housing end cap are properly assembled.
