Abstract

A rapidly changeable air filter, in which the air stream passes from the outside to the inside of the folded filter body which is supported on the inside by a supporting body, the filter interior being closed from one side by a cover and being sealed at the other side by a ring seal via which the filter is attached to an inlet connection piece of a suction fan, the cover (3) being firmly attached to the supporting body (2) and the filter body (1) and provided with an integral or fused-on handle (4), and process for the production of the supporting body and cover, these being produced in a divided mould, in which, in die-casting, the through-holes or openings (9) are formed by projections of the mould walls. <IMAGE>
