An air filtering device and a method of producing the device. The device is constructed from a number of modules of a first module type ( 4 ) and a second module type ( 6 ), which are arranged in series in a row. A module of the first module type ( 4 ) is arranged as an inlet module ( 4 ) with inlets ( 42 ), which is connected in series to modules ( 8, 10: 16 ) of the second module type ( 6 ). One of the latter may include a fan element ( 18 ) or one or more filter elements ( 12, 14 ), and one of them is arranged as an outlet module ( 16 ) and others as through-flow modules ( 8, 10 ). The modules are joined together by locking members ( 32 ) arranged in each module, in such a way that the modules create an enclosed air duct ( 4, 8, 10, 16 ). |
