Abstract:
A tubular filter element for location in a housing for collecting material that is entrained in a gas stream by passing the gas stream through the wall of the filter element, the wall of the filter element comprising a filter medium, the filter element further comprising first and second end fittings by which connections are formed between the filter element and the housing, in which the first end fitting includes a support comprising at least three limbs which support extends between the filter element and the internal side wall of the housing to restrict the filter element against movement within the housing in a direction along the longitudinal axis of the filter element, the three limbs being inclined to the longitudinal axis of the filter element, and in which the second end fitting bears a tang which can be deformed resiliently during formation of a connection between the second end fitting and the housing, and which can be received in a recess in the housing which allows the configuration of the tang to be restored at least partially towards the undeformed configuration.
