Abstract
A grease filter made from metal, in particular, for use in commercial kitchens and in household vapor extractor hoods has impact filter elements with a first row of elongate profiles disposed at distances from one another and with a second row of profiles disposed at distances from one another, the profile rows being at a distance from one another and being offset relative to one another such that the profiles of the second row match with the distances between the first row. A knitted fabric filter or an expanded mesh grid is disposed between the first and second rows of profiles. The profiles have a sound-absorbing material, in particular, sound-absorbing mats, on a side facing away from the air flow. By virtue of this configuration, a high grease efficiency is achieved, there is excellent protection against flame puncture, and noise protection measures can be implemented.
