Abstract
A filter device for filtration of gaseous fluids has a filter housing provided with a receptacle. A first filter element and a second filter element are arranged in the receptacle of the filter housing behind one another in an axial direction of the filter housing. A first bypass that bypasses the first filter element is provided. An inflow side of the second filter element is arranged axially behind the first filter element and is fluidically connected to the first bypass. Fluid to be filtered passes in a flow direction of the fluid through the first bypass to the inflow side of the second filter element.
