Abstract: The invention relates to a filter installation having at least one filter element for the filtering of a crude gas containing impurities, in particular particulate impurities. The crude gas flow to be filtered can be supplied to the filter installation via a crude gas line and at least two filter modules, each having at least one filter element, are provided. Each filter module is fluidly connected to the crude gas line via a module crude gas line through which a part of the crude gas flow can be supplied to the respective filter module. Each module crude gas line has a blocking member through which the supply of the respective partial crude gas flow can be interrupted for the cleaning of the filter element of the respective filter module.
